+<h2>Rebasing changesets</h2><blockquote><pre>typedef struct sqlite3_rebaser sqlite3_rebaser;
+</pre></blockquote><p><b>Important:</b> This interface is <a href="c3ref/experimental.html">experimental</a> and is subject to change without notice.</p><p>
+Suppose there is a site hosting a database in state S0. And that
+modifications are made that move that database to state S1 and a
+changeset recorded (the "local" changeset). Then, a changeset based
+on S0 is received from another site (the "remote" changeset) and 
+applied to the database. The database is then in state 
+(S1+"remote"), where the exact state depends on any conflict
+resolution decisions (OMIT or REPLACE) made while applying "remote".
+Rebasing a changeset is to update it to take those conflict 
+resolution decisions into account, so that the same conflicts
+do not have to be resolved elsewhere in the network. </p>
+
+<p>For example, if both the local and remote changesets contain an
+INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":</p>
+
+<p>  local:  INSERT INTO t1 VALUES(1, 'v1');
+  remote: INSERT INTO t1 VALUES(1, 'v2');</p>
+
+<p>and the conflict resolution is REPLACE, then the INSERT change is
+removed from the local changeset (it was overridden). Or, if the
+conflict resolution was "OMIT", then the local changeset is modified
+to instead contain:</p>
+
+<p>          UPDATE t1 SET b = 'v2' WHERE a=1;</p>
+
+<p>Changes within the local changeset are rebased as follows:</p>
+
+<p><dl>
+<dt>Local INSERT<dd>
+  This may only conflict with a remote INSERT. If the conflict 
+  resolution was OMIT, then add an UPDATE change to the rebased
+  changeset. Or, if the conflict resolution was REPLACE, add
+  nothing to the rebased changeset.</p>
+
+<p><dt>Local DELETE<dd>
+  This may conflict with a remote UPDATE or DELETE. In both cases the
+  only possible resolution is OMIT. If the remote operation was a
+  DELETE, then add no change to the rebased changeset. If the remote
+  operation was an UPDATE, then the old.* fields of change are updated
+  to reflect the new.* values in the UPDATE.</p>
+
+<p><dt>Local UPDATE<dd>
+  This may conflict with a remote UPDATE or DELETE. If it conflicts
+  with a DELETE, and the conflict resolution was OMIT, then the update
+  is changed into an INSERT. Any undefined values in the new.* record
+  from the update change are filled in using the old.* values from
+  the conflicting DELETE. Or, if the conflict resolution was REPLACE,
+  the UPDATE change is simply omitted from the rebased changeset.</p>
+
+<p>  If conflict is with a remote UPDATE and the resolution is OMIT, then
+  the old.* values are rebased using the new.* values in the remote
+  change. Or, if the resolution is REPLACE, then the change is copied
+  into the rebased changeset with updates to columns also updated by
+  the conflicting remote UPDATE removed. If this means no columns would 
+  be updated, the change is omitted.
+</dl></p>
+
+<p>A local change may be rebased against multiple remote changes 
+simultaneously. If a single key is modified by multiple remote 
+changesets, they are combined as follows before the local changeset
+is rebased:</p>
+
+<p><ul>
+   <li> If there has been one or more REPLACE resolutions on a
+        key, it is rebased according to a REPLACE.</p>
+
+<p>   <li> If there have been no REPLACE resolutions on a key, then
+        the local changeset is rebased according to the most recent
+        of the OMIT resolutions.
+</ul></p>
+
+<p>Note that conflict resolutions from multiple remote changesets are 
+combined on a per-field basis, not per-row. This means that in the 
+case of multiple remote UPDATE operations, some fields of a single 
+local change may be rebased for REPLACE while others are rebased for 
+OMIT.</p>
+
+<p>In order to rebase a local changeset, the remote changeset must first
+be applied to the local database using sqlite3changeset_apply_v2() and
+the buffer of rebase information captured. Then:</p>
+
+<p><ol>
+  <li> An sqlite3_rebaser object is created by calling 
+       sqlite3rebaser_create().
+  <li> The new object is configured with the rebase buffer obtained from
+       sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
+       If the local changeset is to be rebased against multiple remote
+       changesets, then sqlite3rebaser_configure() should be called
+       multiple times, in the same order that the multiple
+       sqlite3changeset_apply_v2() calls were made.
+  <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().
+  <li> The sqlite3_rebaser object is deleted by calling
+       sqlite3rebaser_delete().

+
+<p>Changes to rows that do not already appear in the changegroup are

+<h2>Create A New Changegroup Object</h2><blockquote><pre>int sqlite3changegroup_new(sqlite3_changegroup **pp);
+</pre></blockquote><p>
+An sqlite3_changegroup object is used to combine two or more changesets
+(or patchsets) into a single changeset (or patchset). A single changegroup
+object may combine changesets or patchsets, but not both. The output is
+always in the same format as the input.</p>
+
+<p>If successful, this function returns SQLITE_OK and populates (*pp) with
+a pointer to a new sqlite3_changegroup object before returning. The caller
+should eventually free the returned object using a call to 
+sqlite3changegroup_delete(). If an error occurs, an SQLite error code
+(i.e. SQLITE_NOMEM) is returned and *pp is set to NULL.</p>
+
+<p>The usual usage pattern for an sqlite3_changegroup object is as follows:</p>
+
+<p><ul>
+  <li> It is created using a call to sqlite3changegroup_new().</p>
+
+<p>  <li> Zero or more changesets (or patchsets) are added to the object
+       by calling sqlite3changegroup_add().</p>
+
+<p>  <li> The result of combining all input changesets together is obtained 
+       by the application via a call to sqlite3changegroup_output().</p>
+
+<p>  <li> The object is deleted using a call to sqlite3changegroup_delete().
+</ul></p>
+
+<p>Any number of calls to add() and output() may be made between the calls to
+new() and delete(), and in any order.</p>
+
+<p>As well as the regular sqlite3changegroup_add() and 
+sqlite3changegroup_output() functions, also available are the streaming
+versions sqlite3changegroup_add_strm() and sqlite3changegroup_output_strm().

+);
+</pre></blockquote><p>
+Obtain a buffer containing a changeset (or patchset) representing the
+current contents of the changegroup. If the inputs to the changegroup
+were themselves changesets, the output is a changeset. Or, if the
+inputs were patchsets, the output is also a patchset.</p>
+
+<p>As with the output of the sqlite3session_changeset() and
+sqlite3session_patchset() functions, all changes related to a single
+table are grouped together in the output of this function. Tables appear
+in the same order as for the very first changeset added to the changegroup.
+If the second or subsequent changesets added to the changegroup contain
+changes for tables that do not appear in the first changeset, they are
+appended onto the end of the output changeset, again in the order in
+which they are first encountered.</p>
+
+<p>If an error occurs, an SQLite error code is returned and the output
+variables (*pnData) and (*ppData) are set to 0. Otherwise, SQLITE_OK
+is returned and the output variables are set to the size of and a 
+pointer to the output buffer, respectively. In this case it is the
+responsibility of the caller to eventually free the buffer using a

+<h2>Add a Schema to a Changegroup</h2><blockquote><pre>int sqlite3changegroup_schema(sqlite3_changegroup*, sqlite3*, const char *zDb);
+</pre></blockquote><p>
+This method may be used to optionally enforce the rule that the changesets
+added to the changegroup handle must match the schema of database zDb
+("main", "temp", or the name of an attached database). If
+sqlite3changegroup_add() is called to add a changeset that is not compatible
+with the configured schema, SQLITE_SCHEMA is returned and the changegroup
+object is left in an undefined state.</p>
+
+<p>A changeset schema is considered compatible with the database schema in
+the same way as for sqlite3changeset_apply(). Specifically, for each
+table in the changeset, there exists a database table with:</p>
+
+<p><ul>
+  <li> The name identified by the changeset, and
+  <li> at least as many columns as recorded in the changeset, and
+  <li> the primary key columns in the same position as recorded in 
+       the changeset.
+</ul></p>
+
+<p>The output of the changegroup object always has the same schema as the
+database nominated using this function. In cases where changesets passed
+to sqlite3changegroup_add() have fewer columns than the corresponding table
+in the database schema, these are filled in using the default column
+values from the database schema. This makes it possible to combined 
+changesets that have different numbers of columns for a single table
+within a changegroup, provided that they are otherwise compatible.

+in one or more of their PRIMARY KEY columns.</p>

+
+<p><h3>Special sqlite_stat1 Handling</h3></p>
+
+<p>As of SQLite version 3.22.0, the "sqlite_stat1" table is an exception to 
+some of the rules above. In SQLite, the schema of sqlite_stat1 is:
+ <pre>
+ &nbsp;     CREATE TABLE sqlite_stat1(tbl,idx,stat)  
+ </pre></p>
+
+<p>Even though sqlite_stat1 does not have a PRIMARY KEY, changes are 
+recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes 
+are recorded for rows for which (idx IS NULL) is true. However, for such
+rows a zero-length blob (SQL value X'') is stored in the changeset or
+patchset instead of a NULL value. This allows such changesets to be
+manipulated by legacy implementations of sqlite3changeset_invert(),
+concat() and similar.</p>
+
+<p>The sqlite3changeset_apply() function automatically converts the 
+zero-length blob back to a NULL value when updating the sqlite_stat1
+table. However, if the application calls sqlite3changeset_new(),
+sqlite3changeset_old() or sqlite3changeset_conflict on a changeset 
+iterator directly (including on a changeset iterator passed to a
+conflict-handler callback) then the X'' value is returned. The application
+must translate X'' to NULL itself if required.</p>
+
+<p>Legacy (older than 3.22.0) versions of the sessions module cannot capture
+changes made to the sqlite_stat1 table. Legacy versions of the
+sqlite3changeset_apply() function silently ignore any modifications to the
+sqlite_stat1 table that are part of a changeset or patchset.

+<h2>Generate A Changeset From A Session Object</h2><blockquote><pre>int sqlite3session_changeset(
+  sqlite3_session *pSession,      /* Session object */
+  int *pnChangeset,               /* OUT: Size of buffer at *ppChangeset */
+  void **ppChangeset              /* OUT: Buffer containing changeset */
+);
+</pre></blockquote><p>
+Obtain a changeset containing changes to the tables attached to the 
+session object passed as the first argument. If successful, 
+set *ppChangeset to point to a buffer containing the changeset 
+and *pnChangeset to the size of the changeset in bytes before returning
+SQLITE_OK. If an error occurs, set both *ppChangeset and *pnChangeset to
+zero and return an SQLite error code.</p>
+
+<p>A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes,
+each representing a change to a single row of an attached table. An INSERT
+change contains the values of each field of a new database row. A DELETE
+contains the original values of each field of a deleted database row. An
+UPDATE change contains the original values of each field of an updated
+database row along with the updated values for each updated non-primary-key
+column. It is not possible for an UPDATE change to represent a change that
+modifies the values of primary key columns. If such a change is made, it
+is represented in a changeset as a DELETE followed by an INSERT.</p>
+
+<p>Changes are not recorded for rows that have NULL values stored in one or 
+more of their PRIMARY KEY columns. If such a row is inserted or deleted,
+no corresponding change is present in the changesets returned by this
+function. If an existing row with one or more NULL values stored in
+PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
+only an INSERT is appears in the changeset. Similarly, if an existing row
+with non-NULL PRIMARY KEY values is updated so that one or more of its
+PRIMARY KEY columns are set to NULL, the resulting changeset contains a
+DELETE change only.</p>
+
+<p>The contents of a changeset may be traversed using an iterator created
+using the <a href="#sqlite3changeset_start">sqlite3changeset_start()</a> API. A changeset may be applied to
+a database with a compatible schema using the <a href="#sqlite3changeset_apply">sqlite3changeset_apply()</a>
+API.</p>
+
+<p>Within a changeset generated by this function, all changes related to a
+single table are grouped together. In other words, when iterating through
+a changeset or when applying a changeset to a database, all changes related
+to a single table are processed before moving on to the next table. Tables
+are sorted in the same order in which they were attached (or auto-attached)
+to the sqlite3_session object. The order in which the changes related to
+a single table are stored is undefined.</p>
+
+<p>Following a successful call to this function, it is the responsibility of
+the caller to eventually free the buffer that *ppChangeset points to using
+<a href="c3ref/free.html">sqlite3_free()</a>.</p>
+
+<p><h3>Changeset Generation</h3></p>
+
+<p>Once a table has been attached to a session object, the session object
+records the primary key values of all new rows inserted into the table.
+It also records the original primary key and other column values of any
+deleted or updated rows. For each unique primary key value, data is only
+recorded once - the first time a row with said primary key is inserted,
+updated or deleted in the lifetime of the session.</p>
+
+<p>There is one exception to the previous paragraph: when a row is inserted,
+updated or deleted, if one or more of its primary key columns contain a
+NULL value, no record of the change is made.</p>
+
+<p>The session object therefore accumulates two types of records - those
+that consist of primary key values only (created when the user inserts
+a new record) and those that consist of the primary key values and the
+original values of other table columns (created when the users deletes
+or updates a record).</p>
+
+<p>When this function is called, the requested changeset is created using
+both the accumulated records and the current contents of the database
+file. Specifically:</p>
+
+<p><ul>
+  <li> For each record generated by an insert, the database is queried
+       for a row with a matching primary key. If one is found, an INSERT
+       change is added to the changeset. If no such row is found, no change 
+       is added to the changeset.</p>
+
+<p>  <li> For each record generated by an update or delete, the database is 
+       queried for a row with a matching primary key. If such a row is
+       found and one or more of the non-primary key fields have been
+       modified from their original values, an UPDATE change is added to 
+       the changeset. Or, if no such row is found in the table, a DELETE 
+       change is added to the changeset. If there is a row with a matching
+       primary key in the database, but all fields contain their original
+       values, no change is added to the changeset.
+</ul></p>
+
+<p>This means, amongst other things, that if a row is inserted and then later
+deleted while a session object is active, neither the insert nor the delete
+will be present in the changeset. Or if a row is deleted and then later a 
+row with the same primary key values inserted while a session object is
+active, the resulting changeset will contain an UPDATE change instead of
+a DELETE and an INSERT.</p>
+
+<p>When a session object is disabled (see the <a href="#sqlite3session_enable">sqlite3session_enable()</a> API),
+it does not accumulate records when rows are inserted, updated or deleted.
+This may appear to have some counter-intuitive effects if a single row
+is written to more than once during a session. For example, if a row
+is inserted while a session object is enabled, then later deleted while 
+the same session object is disabled, no INSERT record will appear in the
+changeset, even though the delete took place while the session was disabled.
+Or, if one field of a row is updated while a session is disabled, and 
+another field of the same row is updated while the session is enabled, the
+resulting changeset will contain an UPDATE change that updates both fields.

+
+<p>It is possible to create multiple session objects attached to a single

+
+<p>Session objects created using this function should be deleted using the

+If it is not already attached to the session object passed as the first

+
+<p>Argument zFromDb must be the name of a database ("main", "temp" etc.)

+A table is considered compatible if it:</p>
+
+<p><ul>
+  <li> Has the same name,
+  <li> Has the same set of columns declared in the same order, and
+  <li> Has the same PRIMARY KEY definition.
+</ul></p>
+
+<p>If the tables are not compatible, SQLITE_SCHEMA is returned. If the tables
+are compatible but do not have any PRIMARY KEY columns, it is not an error
+but no changes are added to the session object. As with other session
+APIs, tables without PRIMARY KEYs are simply ignored.</p>
+
+<p>This function adds a set of changes to the session object that could be
+used to update the table in database zFrom (call this the "from-table") 
+so that its content is the same as the table attached to the session 
+object (call this the "to-table"). Specifically:</p>
+
+<p><ul>

+
+<p>Non-streaming functions that accept changesets (or patchsets) as input
+require that the entire changeset be stored in a single buffer in memory. 
+Similarly, those that return a changeset or patchset do so by returning 
+a pointer to a single large buffer allocated using sqlite3_malloc(). 
+Normally this is convenient. However, if an application running in a 
+low-memory environment is required to handle very large changesets, the
+large contiguous memory allocations required can become onerous.</p>
+
+<p>In order to avoid this problem, instead of a single large buffer, input
+is passed to a streaming API functions by way of a callback function that
+the sessions module invokes to incrementally request input data as it is
+required. In all cases, a pair of API function parameters such as</p>
+
+<p> <pre>
+ &nbsp;     int nChangeset,
+ &nbsp;     void *pChangeset,
+ </pre></p>
+
+<p>Is replaced by:</p>
+
+<p> <pre>
+ &nbsp;     int (*xInput)(void *pIn, void *pData, int *pnData),
+ &nbsp;     void *pIn,
+ </pre></p>
+
+<p>Each time the xInput callback is invoked by the sessions module, the first
+argument passed is a copy of the supplied pIn context pointer. The second 
+argument, pData, points to a buffer (*pnData) bytes in size. Assuming no 
+error occurs the xInput method should copy up to (*pnData) bytes of data 
+into the buffer and set (*pnData) to the actual number of bytes copied 
+before returning SQLITE_OK. If the input is completely exhausted, (*pnData) 
+should be set to zero to indicate this. Or, if an error occurs, an SQLite 
+error code should be returned. In all cases, if an xInput callback returns
+an error, all processing is abandoned and the streaming API function
+returns a copy of the error code to the caller.</p>
+
+<p>In the case of sqlite3changeset_start_strm(), the xInput callback may be
+invoked by the sessions module at any point during the lifetime of the
+iterator. If such an xInput callback returns an error, the iterator enters
+an error state, whereby all subsequent calls to iterator functions 
+immediately fail with the same error code as returned by xInput.</p>
+
+<p>Similarly, streaming API functions that return changesets (or patchsets)
+return them in chunks by way of a callback function instead of via a
+pointer to a single large buffer. In this case, a pair of parameters such
+as:</p>
+
+<p> <pre>
+ &nbsp;     int *pnChangeset,
+ &nbsp;     void **ppChangeset,
+ </pre></p>
+
+<p>Is replaced by:</p>
+
+<p> <pre>
+ &nbsp;     int (*xOutput)(void *pOut, const void *pData, int nData),
+ &nbsp;     void *pOut
+ </pre></p>
+
+<p>The xOutput callback is invoked zero or more times to return data to
+the application. The first parameter passed to each call is a copy of the
+pOut pointer supplied by the application. The second parameter, pData,
+points to a buffer nData bytes in size containing the chunk of output
+data being returned. If the xOutput callback successfully processes the
+supplied data, it should return SQLITE_OK to indicate success. Otherwise,
+it should return some other SQLite error code. In this case processing
+is immediately abandoned and the streaming API function returns a copy
+of the xOutput error code to the application.</p>
+
+<p>The sessions module never invokes an xOutput callback with the third 
+parameter set to a value less than or equal to zero. Other than this,
+no guarantees are made as to the size of the chunks of data returned.

+Apply a changeset or patchset to a database. These functions attempt to
+update the "main" database attached to handle db with the changes found in
+the changeset passed via the second and third arguments. </p>
+
+<p>The fourth argument (xFilter) passed to these functions is the "filter
+callback". If it is not NULL, then for each table affected by at least one
+change in the changeset, the filter callback is invoked with
+the table name as the second argument, and a copy of the context pointer
+passed as the sixth argument as the first. If the "filter callback"
+returns zero, then no attempt is made to apply any changes to the table.
+Otherwise, if the return value is non-zero or the xFilter argument to
+is NULL, all changes related to the table are attempted.</p>
+
+<p>For each table that is not excluded by the filter callback, this function 
+tests that the target database contains a compatible table. A table is 
+considered compatible if all of the following are true:</p>
+
+<p><ul>
+  <li> The table has the same name as the name recorded in the 
+       changeset, and
+  <li> The table has at least as many columns as recorded in the 
+       changeset, and
+  <li> The table has primary key columns in the same position as 
+       recorded in the changeset.
+</ul></p>
+
+<p>If there is no compatible table, it is not an error, but none of the
+changes associated with the table are applied. A warning message is issued
+via the sqlite3_log() mechanism with the error code SQLITE_SCHEMA. At most
+one such warning is issued for each table in the changeset.</p>
+
+<p>For each change for which there is a compatible table, an attempt is made 
+to modify the table contents according to the UPDATE, INSERT or DELETE 
+change. If a change cannot be applied cleanly, the conflict handler 
+function passed as the fifth argument to sqlite3changeset_apply() may be 
+invoked. A description of exactly when the conflict handler is invoked for 
+each type of change is below.</p>
+
+<p>Unlike the xFilter argument, xConflict may not be passed NULL. The results
+of passing anything other than a valid function pointer as the xConflict
+argument are undefined.</p>

+  SAVEPOINT is committed if the changeset or patchset is successfully

+  causes the sessions module to omit this savepoint. In this case, if the

+
+<p><dt>SQLITE_CHANGESETAPPLY_INVERT <dd>
+  Invert the changeset before applying it. This is equivalent to inverting
+  a changeset using sqlite3changeset_invert() before applying it. It is
+  an error to specify this flag with a patchset.</p>
+
+<p><dt>SQLITE_CHANGESETAPPLY_IGNORENOOP <dd>
+  Do not invoke the conflict handler callback for any changes that
+  would not actually modify the database even if they were applied.
+  Specifically, this means that the conflict handler is not invoked
+  for:
+   <ul>
+   <li>a delete change if the row being deleted cannot be found, 
+   <li>an update change if the modified fields are already set to

+       the row being inserted.
+   </ul></p>
+
+<p><dt>SQLITE_CHANGESETAPPLY_FKNOACTION <dd>
+  If this flag it set, then all foreign key constraints in the target

+  or SET DEFAULT.

+<p>These pages define the C-language interface for the SQLite
+<a href="../sessionintro.html">session extension</a>.
+This is not a tutorial. These pages are designed to be precise, not
+easy to read.  A tutorial is <a href="../sessionintro.html">available separately</a>.
+
+<p>This version of the C-language interface reference is
+broken down into small pages for easy viewing.  The
+same content is also available as a
+<a href="../session.html">single large HTML file</a>
+for those who prefer that format.</p>
+
+<p>The content on these pages is extracted from comments
+in the source code.</p>
+
+<p>The interface is broken down into three categories:</p>
+
+<ol>
+<li><p><a href="../session/objlist.html"><b>List Of Objects.</b></a>
+    This is a list of the three abstract objects used by the SQLite session
+    module.
+
+<li><p><a href="../session/constlist.html"><b>List Of Constants.</b></a>
+    This is a list of numeric constants used by the SQLite session module
+    and represented by #defines in the sqlite3session.h header file. There
+    are constants passed to conflict handler callbacks to indicate the type
+    of conflict, and constants returned by the conflict handler to indicate
+    how the conflict should be resolved.
+
+<li><p><a href="../session/funclist.html"><b>List Of Functions.</b></a>
+    This is a list of all SQLite session module functions.

+<a href="../session/intro.html"><h2>Session Module C Interface</h2></a><h2>Rebasing changesets</h2><blockquote><pre>typedef struct sqlite3_rebaser sqlite3_rebaser;
+</pre></blockquote><p><b>Important:</b> This interface is <a href="../c3ref/experimental.html">experimental</a> and is subject to change without notice.</p><p>
+Suppose there is a site hosting a database in state S0. And that
+modifications are made that move that database to state S1 and a
+changeset recorded (the "local" changeset). Then, a changeset based
+on S0 is received from another site (the "remote" changeset) and 
+applied to the database. The database is then in state 
+(S1+"remote"), where the exact state depends on any conflict
+resolution decisions (OMIT or REPLACE) made while applying "remote".
+Rebasing a changeset is to update it to take those conflict 
+resolution decisions into account, so that the same conflicts
+do not have to be resolved elsewhere in the network. </p>
+
+<p>For example, if both the local and remote changesets contain an
+INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":</p>
+
+<p>  local:  INSERT INTO t1 VALUES(1, 'v1');
+  remote: INSERT INTO t1 VALUES(1, 'v2');</p>
+
+<p>and the conflict resolution is REPLACE, then the INSERT change is
+removed from the local changeset (it was overridden). Or, if the
+conflict resolution was "OMIT", then the local changeset is modified
+to instead contain:</p>
+
+<p>          UPDATE t1 SET b = 'v2' WHERE a=1;</p>
+
+<p>Changes within the local changeset are rebased as follows:</p>
+
+<p><dl>
+<dt>Local INSERT<dd>
+  This may only conflict with a remote INSERT. If the conflict 
+  resolution was OMIT, then add an UPDATE change to the rebased
+  changeset. Or, if the conflict resolution was REPLACE, add
+  nothing to the rebased changeset.</p>
+
+<p><dt>Local DELETE<dd>
+  This may conflict with a remote UPDATE or DELETE. In both cases the
+  only possible resolution is OMIT. If the remote operation was a
+  DELETE, then add no change to the rebased changeset. If the remote
+  operation was an UPDATE, then the old.* fields of change are updated
+  to reflect the new.* values in the UPDATE.</p>
+
+<p><dt>Local UPDATE<dd>
+  This may conflict with a remote UPDATE or DELETE. If it conflicts
+  with a DELETE, and the conflict resolution was OMIT, then the update
+  is changed into an INSERT. Any undefined values in the new.* record
+  from the update change are filled in using the old.* values from
+  the conflicting DELETE. Or, if the conflict resolution was REPLACE,
+  the UPDATE change is simply omitted from the rebased changeset.</p>
+
+<p>  If conflict is with a remote UPDATE and the resolution is OMIT, then
+  the old.* values are rebased using the new.* values in the remote
+  change. Or, if the resolution is REPLACE, then the change is copied
+  into the rebased changeset with updates to columns also updated by
+  the conflicting remote UPDATE removed. If this means no columns would 
+  be updated, the change is omitted.
+</dl></p>
+
+<p>A local change may be rebased against multiple remote changes 
+simultaneously. If a single key is modified by multiple remote 
+changesets, they are combined as follows before the local changeset
+is rebased:</p>
+
+<p><ul>
+   <li> If there has been one or more REPLACE resolutions on a
+        key, it is rebased according to a REPLACE.</p>
+
+<p>   <li> If there have been no REPLACE resolutions on a key, then
+        the local changeset is rebased according to the most recent
+        of the OMIT resolutions.
+</ul></p>
+
+<p>Note that conflict resolutions from multiple remote changesets are 
+combined on a per-field basis, not per-row. This means that in the 
+case of multiple remote UPDATE operations, some fields of a single 
+local change may be rebased for REPLACE while others are rebased for 
+OMIT.</p>
+
+<p>In order to rebase a local changeset, the remote changeset must first
+be applied to the local database using sqlite3changeset_apply_v2() and
+the buffer of rebase information captured. Then:</p>
+
+<p><ol>
+  <li> An sqlite3_rebaser object is created by calling 
+       sqlite3rebaser_create().
+  <li> The new object is configured with the rebase buffer obtained from
+       sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
+       If the local changeset is to be rebased against multiple remote
+       changesets, then sqlite3rebaser_configure() should be called
+       multiple times, in the same order that the multiple
+       sqlite3changeset_apply_v2() calls were made.
+  <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().
+  <li> The sqlite3_rebaser object is deleted by calling
+       sqlite3rebaser_delete().
+</ol>

+<p>Changes to rows that do not already appear in the changegroup are
+simply copied into it. Or, if both the new changeset and the changegroup
+contain changes that apply to a single row, the final contents of the
+changegroup depends on the type of each change, as follows:</p>
+
+<p><table border=1 style="margin-left:8ex;margin-right:8ex">
+  <tr><th style="white-space:pre">Existing Change  </th>
+      <th style="white-space:pre">New Change       </th>
+      <th>Output Change
+  <tr><td>INSERT <td>INSERT <td>
+      The new change is ignored. This case does not occur if the new
+      changeset was recorded immediately after the changesets already
+      added to the changegroup.
+  <tr><td>INSERT <td>UPDATE <td>
+      The INSERT change remains in the changegroup. The values in the 
+      INSERT change are modified as if the row was inserted by the
+      existing change and then updated according to the new change.
+  <tr><td>INSERT <td>DELETE <td>
+      The existing INSERT is removed from the changegroup. The DELETE is
+      not added.
+  <tr><td>UPDATE <td>INSERT <td>
+      The new change is ignored. This case does not occur if the new
+      changeset was recorded immediately after the changesets already
+      added to the changegroup.
+  <tr><td>UPDATE <td>UPDATE <td>
+      The existing UPDATE remains within the changegroup. It is amended 
+      so that the accompanying values are as if the row was updated once 
+      by the existing change and then again by the new change.
+  <tr><td>UPDATE <td>DELETE <td>
+      The existing UPDATE is replaced by the new DELETE within the
+      changegroup.
+  <tr><td>DELETE <td>INSERT <td>
+      If one or more of the column values in the row inserted by the
+      new change differ from those in the row deleted by the existing 
+      change, the existing DELETE is replaced by an UPDATE within the
+      changegroup. Otherwise, if the inserted row is exactly the same 
+      as the deleted row, the existing DELETE is simply discarded.
+  <tr><td>DELETE <td>UPDATE <td>
+      The new change is ignored. This case does not occur if the new
+      changeset was recorded immediately after the changesets already
+      added to the changegroup.
+  <tr><td>DELETE <td>DELETE <td>
+      The new change is ignored. This case does not occur if the new
+      changeset was recorded immediately after the changesets already
+      added to the changegroup.
+</table></p>
+
+<p>If the new changeset contains changes to a table that is already present
+in the changegroup, then the number of columns and the position of the
+primary key columns for the table must be consistent. If this is not the
+case, this function fails with SQLITE_SCHEMA. Except, if the changegroup
+object has been configured with a database schema using the
+sqlite3changegroup_schema() API, then it is possible to combine changesets
+with different numbers of columns for a single table, provided that
+they are otherwise compatible.</p>
+
+<p>If the input changeset appears to be corrupt and the corruption is
+detected, SQLITE_CORRUPT is returned. Or, if an out-of-memory condition
+occurs during processing, this function returns SQLITE_NOMEM. </p>
+
+<p>In all cases, if an error occurs the state of the final contents of the
+changegroup is undefined. If no error occurs, SQLITE_OK is returned.

+</table></p>
+
+<p>Non-streaming functions that accept changesets (or patchsets) as input
+require that the entire changeset be stored in a single buffer in memory. 
+Similarly, those that return a changeset or patchset do so by returning 
+a pointer to a single large buffer allocated using sqlite3_malloc(). 
+Normally this is convenient. However, if an application running in a 
+low-memory environment is required to handle very large changesets, the
+large contiguous memory allocations required can become onerous.</p>
+
+<p>In order to avoid this problem, instead of a single large buffer, input
+is passed to a streaming API functions by way of a callback function that
+the sessions module invokes to incrementally request input data as it is
+required. In all cases, a pair of API function parameters such as</p>
+
+<p> <pre>
+ &nbsp;     int nChangeset,
+ &nbsp;     void *pChangeset,
+ </pre></p>
+
+<p>Is replaced by:</p>
+
+<p> <pre>
+ &nbsp;     int (*xInput)(void *pIn, void *pData, int *pnData),
+ &nbsp;     void *pIn,
+ </pre></p>
+
+<p>Each time the xInput callback is invoked by the sessions module, the first
+argument passed is a copy of the supplied pIn context pointer. The second 
+argument, pData, points to a buffer (*pnData) bytes in size. Assuming no 
+error occurs the xInput method should copy up to (*pnData) bytes of data 
+into the buffer and set (*pnData) to the actual number of bytes copied 
+before returning SQLITE_OK. If the input is completely exhausted, (*pnData) 
+should be set to zero to indicate this. Or, if an error occurs, an SQLite 
+error code should be returned. In all cases, if an xInput callback returns
+an error, all processing is abandoned and the streaming API function
+returns a copy of the error code to the caller.</p>
+
+<p>In the case of sqlite3changeset_start_strm(), the xInput callback may be
+invoked by the sessions module at any point during the lifetime of the
+iterator. If such an xInput callback returns an error, the iterator enters
+an error state, whereby all subsequent calls to iterator functions 
+immediately fail with the same error code as returned by xInput.</p>
+
+<p>Similarly, streaming API functions that return changesets (or patchsets)
+return them in chunks by way of a callback function instead of via a
+pointer to a single large buffer. In this case, a pair of parameters such
+as:</p>
+
+<p> <pre>
+ &nbsp;     int *pnChangeset,
+ &nbsp;     void **ppChangeset,
+ </pre></p>
+
+<p>Is replaced by:</p>
+
+<p> <pre>
+ &nbsp;     int (*xOutput)(void *pOut, const void *pData, int nData),
+ &nbsp;     void *pOut
+ </pre></p>
+
+<p>The xOutput callback is invoked zero or more times to return data to
+the application. The first parameter passed to each call is a copy of the
+pOut pointer supplied by the application. The second parameter, pData,
+points to a buffer nData bytes in size containing the chunk of output
+data being returned. If the xOutput callback successfully processes the
+supplied data, it should return SQLITE_OK to indicate success. Otherwise,
+it should return some other SQLite error code. In this case processing
+is immediately abandoned and the streaming API function returns a copy
+of the xOutput error code to the application.</p>
+
+<p>The sessions module never invokes an xOutput callback with the third 
+parameter set to a value less than or equal to zero. Other than this,
+no guarantees are made as to the size of the chunks of data returned.

+</pre></blockquote><p>
+An sqlite3_changegroup object is used to combine two or more changesets
+(or patchsets) into a single changeset (or patchset). A single changegroup
+object may combine changesets or patchsets, but not both. The output is
+always in the same format as the input.</p>
+
+<p>If successful, this function returns SQLITE_OK and populates (*pp) with
+a pointer to a new sqlite3_changegroup object before returning. The caller
+should eventually free the returned object using a call to 
+sqlite3changegroup_delete(). If an error occurs, an SQLite error code
+(i.e. SQLITE_NOMEM) is returned and *pp is set to NULL.</p>
+
+<p>The usual usage pattern for an sqlite3_changegroup object is as follows:</p>
+
+<p><ul>
+  <li> It is created using a call to sqlite3changegroup_new().</p>
+
+<p>  <li> Zero or more changesets (or patchsets) are added to the object
+       by calling sqlite3changegroup_add().</p>
+
+<p>  <li> The result of combining all input changesets together is obtained 
+       by the application via a call to sqlite3changegroup_output().</p>
+
+<p>  <li> The object is deleted using a call to sqlite3changegroup_delete().
+</ul></p>
+
+<p>Any number of calls to add() and output() may be made between the calls to
+new() and delete(), and in any order.</p>
+
+<p>As well as the regular sqlite3changegroup_add() and 
+sqlite3changegroup_output() functions, also available are the streaming
+versions sqlite3changegroup_add_strm() and sqlite3changegroup_output_strm().

+<p>The fourth argument (xFilter) passed to these functions is the "filter

+change in the changeset, the filter callback is invoked with

+passed as the sixth argument as the first. If the "filter callback"

+Otherwise, if the return value is non-zero or the xFilter argument to

+changes associated with the table are applied. A warning message is issued
+via the sqlite3_log() mechanism with the error code SQLITE_SCHEMA. At most
+one such warning is issued for each table in the changeset.</p>
+
+<p>For each change for which there is a compatible table, an attempt is made 
+to modify the table contents according to the UPDATE, INSERT or DELETE 
+change. If a change cannot be applied cleanly, the conflict handler 
+function passed as the fifth argument to sqlite3changeset_apply() may be 
+invoked. A description of exactly when the conflict handler is invoked for

+<p>Each time the conflict handler function is invoked, it must return one
+of <a href="../session/c_changeset_abort.html">SQLITE_CHANGESET_OMIT</a>, <a href="../session/c_changeset_abort.html">SQLITE_CHANGESET_ABORT</a> or 
+<a href="../session/c_changeset_abort.html">SQLITE_CHANGESET_REPLACE</a>. SQLITE_CHANGESET_REPLACE may only be returned
+if the second argument passed to the conflict handler is either
+SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT. If the conflict-handler
+returns an illegal value, any changes already made are rolled back and
+the call to sqlite3changeset_apply() returns SQLITE_MISUSE. Different 
+actions are taken by sqlite3changeset_apply() depending on the value
+returned by each invocation of the conflict-handler function. Refer to
+the documentation for the three 
+<a href="../session/c_changeset_abort.html">available return values</a> for details.</p>
+
+<p><dl>
+<dt>DELETE Changes<dd>
+  For each DELETE change, the function checks if the target database 
+  contains a row with the same primary key value (or values) as the 
+  original row values stored in the changeset. If it does, and the values 
+  stored in all non-primary key columns also match the values stored in 
+  the changeset the row is deleted from the target database.</p>
+
+<p>  If a row with matching primary key values is found, but one or more of
+  the non-primary key fields contains a value different from the original
+  row value stored in the changeset, the conflict-handler function is
+  invoked with <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_DATA</a> as the second argument. If the
+  database table has more columns than are recorded in the changeset,
+  only the values of those non-primary key fields are compared against
+  the current database contents - any trailing database table columns
+  are ignored.</p>
+
+<p>  If no row with matching primary key values is found in the database,
+  the conflict-handler function is invoked with <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_NOTFOUND</a>
+  passed as the second argument.</p>
+
+<p>  If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT
+  (which can only happen if a foreign key constraint is violated), the
+  conflict-handler function is invoked with <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_CONSTRAINT</a>
+  passed as the second argument. This includes the case where the DELETE
+  operation is attempted because an earlier call to the conflict handler
+  function returned <a href="../session/c_changeset_abort.html">SQLITE_CHANGESET_REPLACE</a>.</p>
+
+<p><dt>INSERT Changes<dd>
+  For each INSERT change, an attempt is made to insert the new row into
+  the database. If the changeset row contains fewer fields than the
+  database table, the trailing fields are populated with their default
+  values.</p>
+
+<p>  If the attempt to insert the row fails because the database already 
+  contains a row with the same primary key values, the conflict handler
+  function is invoked with the second argument set to 
+  <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_CONFLICT</a>.</p>
+
+<p>  If the attempt to insert the row fails because of some other constraint
+  violation (e.g. NOT NULL or UNIQUE), the conflict handler function is 
+  invoked with the second argument set to <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_CONSTRAINT</a>.
+  This includes the case where the INSERT operation is re-attempted because 
+  an earlier call to the conflict handler function returned 
+  <a href="../session/c_changeset_abort.html">SQLITE_CHANGESET_REPLACE</a>.</p>
+
+<p><dt>UPDATE Changes<dd>
+  For each UPDATE change, the function checks if the target database 
+  contains a row with the same primary key value (or values) as the 
+  original row values stored in the changeset. If it does, and the values 
+  stored in all modified non-primary key columns also match the values
+  stored in the changeset the row is updated within the target database.</p>
+
+<p>  If a row with matching primary key values is found, but one or more of
+  the modified non-primary key fields contains a value different from an
+  original row value stored in the changeset, the conflict-handler function
+  is invoked with <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_DATA</a> as the second argument. Since
+  UPDATE changes only contain values for non-primary key fields that are
+  to be modified, only those fields need to match the original values to
+  avoid the SQLITE_CHANGESET_DATA conflict-handler callback.</p>
+
+<p>  If no row with matching primary key values is found in the database,
+  the conflict-handler function is invoked with <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_NOTFOUND</a>
+  passed as the second argument.</p>
+
+<p>  If the UPDATE operation is attempted, but SQLite returns 
+  SQLITE_CONSTRAINT, the conflict-handler function is invoked with 
+  <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_CONSTRAINT</a> passed as the second argument.
+  This includes the case where the UPDATE operation is attempted after 
+  an earlier call to the conflict handler function returned
+  <a href="../session/c_changeset_abort.html">SQLITE_CHANGESET_REPLACE</a>.  
+</dl></p>
+
+<p>It is safe to execute SQL statements, including those that write to the
+table that the callback related to, from within the xConflict callback.
+This can be used to further customize the application's conflict
+resolution strategy.</p>
+
+<p>All changes made by these functions are enclosed in a savepoint transaction.
+If any other error (aside from a constraint failure when attempting to
+write to the target database) occurs, then the savepoint transaction is
+rolled back, restoring the target database to its original state, and an 
+SQLite error code returned.</p>
+
+<p>If the output parameters (ppRebase) and (pnRebase) are non-NULL and
+the input is a changeset (not a patchset), then sqlite3changeset_apply_v2()
+may set (*ppRebase) to point to a "rebase" that may be used with the 
+sqlite3_rebaser APIs buffer before returning. In this case (*pnRebase)
+is set to the size of the buffer in bytes. It is the responsibility of the
+caller to eventually free any such buffer using sqlite3_free(). The buffer
+is only allocated and populated if one or more conflicts were encountered
+while applying the patchset. See comments surrounding the sqlite3_rebaser
+APIs for further details.</p>
+
+<p>The behavior of sqlite3changeset_apply_v2() and its streaming equivalent
+may be modified by passing a combination of
+<a href="../session/c_changesetapply_fknoaction.html">supported flags</a> as the 9th parameter.</p>
+
+<p>Note that the sqlite3changeset_apply_v2() API is still <b>experimental</b>
+and therefore subject to change.

+This function is used to "invert" a changeset object. Applying an inverted

+<p>This function does not change the order in which changes appear within

+
+<p>If successful, a pointer to a buffer containing the inverted changeset
+is stored in *ppOut, the size of the same buffer is stored in *pnOut, and

+Create an iterator used to iterate through the contents of a changeset.
+If successful, *pp is set to point to the iterator handle and SQLITE_OK
+is returned. Otherwise, if an error occurs, *pp is set to zero and an
+SQLite error code is returned.</p>
+
+<p>The following functions can be used to advance and query a changeset 
+iterator created by this function:</p>
+
+<p><ul>
+  <li> <a href="../session/sqlite3changeset_next.html">sqlite3changeset_next()</a>
+  <li> <a href="../session/sqlite3changeset_op.html">sqlite3changeset_op()</a>
+  <li> <a href="../session/sqlite3changeset_new.html">sqlite3changeset_new()</a>
+  <li> <a href="../session/sqlite3changeset_old.html">sqlite3changeset_old()</a>
+</ul></p>
+
+<p>It is the responsibility of the caller to eventually destroy the iterator
+by passing it to <a href="../session/sqlite3changeset_finalize.html">sqlite3changeset_finalize()</a>. The buffer containing the
+changeset (pChangeset) must remain valid until after the iterator is
+destroyed.</p>
+
+<p>Assuming the changeset blob was created by one of the
+<a href="../session/sqlite3session_changeset.html">sqlite3session_changeset()</a>, <a href="../session/sqlite3changeset_concat.html">sqlite3changeset_concat()</a> or
+<a href="../session/sqlite3changeset_invert.html">sqlite3changeset_invert()</a> functions, all changes within the changeset 
+that apply to a single table are grouped together. This means that when 
+an application iterates through a changeset using an iterator created by 
+this function, all changes that relate to a single table are visited 
+consecutively. There is no chance that the iterator will visit a change 
+the applies to table X, then one for table Y, and then later on visit 
+another change for table X.</p>
+
+<p>The behavior of sqlite3changeset_start_v2() and its streaming equivalent
+may be modified by passing a combination of
+<a href="../session/c_changesetstart_invert.html">supported flags</a> as the 4th parameter.</p>
+
+<p>Note that the sqlite3changeset_start_v2() API is still <b>experimental</b>
+and therefore subject to change.

+<a href="../session/intro.html"><h2>Session Module C Interface</h2></a><h2>Attach A Table To A Session Object</h2><blockquote><pre>int sqlite3session_attach(
+  sqlite3_session *pSession,      /* Session object */
+  const char *zTab                /* Table name */
+);
+</pre></blockquote><p>
+If argument zTab is not NULL, then it is the name of a table to attach
+to the session object passed as the first argument. All subsequent changes 
+made to the table while the session object is enabled will be recorded. See 
+documentation for <a href="../session/sqlite3session_changeset.html">sqlite3session_changeset()</a> for further details.</p>
+
+<p>Or, if argument zTab is NULL, then changes are recorded for all tables
+in the database. If additional tables are added to the database (by 
+executing "CREATE TABLE" statements) after this call is made, changes for 
+the new tables are also recorded.</p>
+
+<p>Changes can only be recorded for tables that have a PRIMARY KEY explicitly
+defined as part of their CREATE TABLE statement. It does not matter if the 
+PRIMARY KEY is an "INTEGER PRIMARY KEY" (rowid alias) or not. The PRIMARY
+KEY may consist of a single column, or may be a composite key.</p>
+
+<p>It is not an error if the named table does not exist in the database. Nor
+is it an error if the named table does not have a PRIMARY KEY. However,
+no changes will be recorded in either of these scenarios.</p>
+
+<p>Changes are not recorded for individual rows that have NULL values stored
+in one or more of their PRIMARY KEY columns.</p>
+
+<p>SQLITE_OK is returned if the call completes without error. Or, if an error 
+occurs, an SQLite error code (e.g. SQLITE_NOMEM) is returned.</p>
+
+<p><h3>Special sqlite_stat1 Handling</h3></p>
+
+<p>As of SQLite version 3.22.0, the "sqlite_stat1" table is an exception to 
+some of the rules above. In SQLite, the schema of sqlite_stat1 is:
+ <pre>
+ &nbsp;     CREATE TABLE sqlite_stat1(tbl,idx,stat)  
+ </pre></p>
+
+<p>Even though sqlite_stat1 does not have a PRIMARY KEY, changes are 
+recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes 
+are recorded for rows for which (idx IS NULL) is true. However, for such
+rows a zero-length blob (SQL value X'') is stored in the changeset or
+patchset instead of a NULL value. This allows such changesets to be
+manipulated by legacy implementations of sqlite3changeset_invert(),
+concat() and similar.</p>
+
+<p>The sqlite3changeset_apply() function automatically converts the 
+zero-length blob back to a NULL value when updating the sqlite_stat1
+table. However, if the application calls sqlite3changeset_new(),
+sqlite3changeset_old() or sqlite3changeset_conflict on a changeset 
+iterator directly (including on a changeset iterator passed to a
+conflict-handler callback) then the X'' value is returned. The application
+must translate X'' to NULL itself if required.</p>
+
+<p>Legacy (older than 3.22.0) versions of the sessions module cannot capture
+changes made to the sqlite_stat1 table. Legacy versions of the
+sqlite3changeset_apply() function silently ignore any modifications to the
+sqlite_stat1 table that are part of a changeset or patchset.
+</p><p>See also lists of
+  <a href="../session/objlist.html">Objects</a>,

+<a href="../session/intro.html"><h2>Session Module C Interface</h2></a><h2>Generate A Changeset From A Session Object</h2><blockquote><pre>int sqlite3session_changeset(
+  sqlite3_session *pSession,      /* Session object */
+  int *pnChangeset,               /* OUT: Size of buffer at *ppChangeset */
+  void **ppChangeset              /* OUT: Buffer containing changeset */
+);
+</pre></blockquote><p>
+Obtain a changeset containing changes to the tables attached to the 
+session object passed as the first argument. If successful, 
+set *ppChangeset to point to a buffer containing the changeset 
+and *pnChangeset to the size of the changeset in bytes before returning
+SQLITE_OK. If an error occurs, set both *ppChangeset and *pnChangeset to
+zero and return an SQLite error code.</p>
+
+<p>A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes,
+each representing a change to a single row of an attached table. An INSERT
+change contains the values of each field of a new database row. A DELETE
+contains the original values of each field of a deleted database row. An
+UPDATE change contains the original values of each field of an updated
+database row along with the updated values for each updated non-primary-key
+column. It is not possible for an UPDATE change to represent a change that
+modifies the values of primary key columns. If such a change is made, it
+is represented in a changeset as a DELETE followed by an INSERT.</p>
+
+<p>Changes are not recorded for rows that have NULL values stored in one or 
+more of their PRIMARY KEY columns. If such a row is inserted or deleted,
+no corresponding change is present in the changesets returned by this
+function. If an existing row with one or more NULL values stored in
+PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
+only an INSERT is appears in the changeset. Similarly, if an existing row
+with non-NULL PRIMARY KEY values is updated so that one or more of its
+PRIMARY KEY columns are set to NULL, the resulting changeset contains a
+DELETE change only.</p>
+
+<p>The contents of a changeset may be traversed using an iterator created
+using the <a href="../session/sqlite3changeset_start.html">sqlite3changeset_start()</a> API. A changeset may be applied to
+a database with a compatible schema using the <a href="../session/sqlite3changeset_apply.html">sqlite3changeset_apply()</a>
+API.</p>
+
+<p>Within a changeset generated by this function, all changes related to a
+single table are grouped together. In other words, when iterating through
+a changeset or when applying a changeset to a database, all changes related
+to a single table are processed before moving on to the next table. Tables
+are sorted in the same order in which they were attached (or auto-attached)
+to the sqlite3_session object. The order in which the changes related to
+a single table are stored is undefined.</p>
+
+<p>Following a successful call to this function, it is the responsibility of
+the caller to eventually free the buffer that *ppChangeset points to using
+<a href="../c3ref/free.html">sqlite3_free()</a>.</p>
+
+<p><h3>Changeset Generation</h3></p>
+
+<p>Once a table has been attached to a session object, the session object
+records the primary key values of all new rows inserted into the table.
+It also records the original primary key and other column values of any
+deleted or updated rows. For each unique primary key value, data is only
+recorded once - the first time a row with said primary key is inserted,
+updated or deleted in the lifetime of the session.</p>
+
+<p>There is one exception to the previous paragraph: when a row is inserted,
+updated or deleted, if one or more of its primary key columns contain a
+NULL value, no record of the change is made.</p>
+
+<p>The session object therefore accumulates two types of records - those
+that consist of primary key values only (created when the user inserts
+a new record) and those that consist of the primary key values and the
+original values of other table columns (created when the users deletes
+or updates a record).</p>
+
+<p>When this function is called, the requested changeset is created using
+both the accumulated records and the current contents of the database
+file. Specifically:</p>
+
+<p><ul>
+  <li> For each record generated by an insert, the database is queried
+       for a row with a matching primary key. If one is found, an INSERT
+       change is added to the changeset. If no such row is found, no change 
+       is added to the changeset.</p>
+
+<p>  <li> For each record generated by an update or delete, the database is 
+       queried for a row with a matching primary key. If such a row is
+       found and one or more of the non-primary key fields have been
+       modified from their original values, an UPDATE change is added to 
+       the changeset. Or, if no such row is found in the table, a DELETE 
+       change is added to the changeset. If there is a row with a matching
+       primary key in the database, but all fields contain their original
+       values, no change is added to the changeset.
+</ul></p>
+
+<p>This means, amongst other things, that if a row is inserted and then later
+deleted while a session object is active, neither the insert nor the delete
+will be present in the changeset. Or if a row is deleted and then later a 
+row with the same primary key values inserted while a session object is
+active, the resulting changeset will contain an UPDATE change instead of
+a DELETE and an INSERT.</p>
+
+<p>When a session object is disabled (see the <a href="../session/sqlite3session_enable.html">sqlite3session_enable()</a> API),
+it does not accumulate records when rows are inserted, updated or deleted.
+This may appear to have some counter-intuitive effects if a single row
+is written to more than once during a session. For example, if a row
+is inserted while a session object is enabled, then later deleted while 
+the same session object is disabled, no INSERT record will appear in the
+changeset, even though the delete took place while the session was disabled.
+Or, if one field of a row is updated while a session is disabled, and 
+another field of the same row is updated while the session is enabled, the
+resulting changeset will contain an UPDATE change that updates both fields.

+  sqlite3_session *pSession,
+  const char *zFromDb,
+  const char *zTbl,
+  char **pzErrMsg
+);
+</pre></blockquote><p>
+If it is not already attached to the session object passed as the first
+argument, this function attaches table zTbl in the same manner as the
+<a href="../session/sqlite3session_attach.html">sqlite3session_attach()</a> function. If zTbl does not exist, or if it
+does not have a primary key, this function is a no-op (but does not return
+an error).</p>
+
+<p>Argument zFromDb must be the name of a database ("main", "temp" etc.)
+attached to the same database handle as the session object that contains 
+a table compatible with the table attached to the session by this function.
+A table is considered compatible if it:</p>
+
+<p><ul>
+  <li> Has the same name,
+  <li> Has the same set of columns declared in the same order, and
+  <li> Has the same PRIMARY KEY definition.
+</ul></p>
+
+<p>If the tables are not compatible, SQLITE_SCHEMA is returned. If the tables
+are compatible but do not have any PRIMARY KEY columns, it is not an error
+but no changes are added to the session object. As with other session
+APIs, tables without PRIMARY KEYs are simply ignored.</p>
+
+<p>This function adds a set of changes to the session object that could be
+used to update the table in database zFrom (call this the "from-table") 
+so that its content is the same as the table attached to the session 
+object (call this the "to-table"). Specifically:</p>
+
+<p><ul>
+  <li> For each row (primary key) that exists in the to-table but not in 
+    the from-table, an INSERT record is added to the session object.</p>
+
+<p>  <li> For each row (primary key) that exists in the to-table but not in 
+    the from-table, a DELETE record is added to the session object.</p>
+
+<p>  <li> For each row (primary key) that exists in both tables, but features 
+    different non-PK values in each, an UPDATE record is added to the
+    session.  
+</ul></p>
+
+<p>To clarify, if this function is called and then a changeset constructed
+using <a href="../session/sqlite3session_changeset.html">sqlite3session_changeset()</a>, then after applying that changeset to 
+database zFrom the contents of the two compatible tables would be 
+identical.</p>
+
+<p>It an error if database zFrom does not exist or does not contain the
+required compatible table.</p>
+
+<p>If the operation is successful, SQLITE_OK is returned. Otherwise, an SQLite
+error code. In this case, if argument pzErrMsg is not NULL, *pzErrMsg
+may be set to point to a buffer containing an English language error 
+message. It is the responsibility of the caller to free this buffer using
+sqlite3_free().

+
+<p>The session extension provide a mechanism for conviently recording
+changes to some or all of certain tables in an SQLite database, and
+packaging those changes into a "changeset" or "patchset" file that can
+later be used to apply the same set of changes to another database with
+the same schema and compatible starting data.  A "changeset" may
+also be inverted and used to "undo" a session.
+
+</p><p>This document is an introduction to the session extension.
+The details of the interface are in the separate
+<a href="session/intro.html">Session Extension C-language Interface</a> document.
+
+</p><h2 id="typical_use_case"><span>1.1. </span>Typical Use Case</h2>
+
+<p>Suppose SQLite is used as the <a href="appfileformat.html">application file format</a> for a
+particular design application.  Two users, Alice and Bob, each start
+with a baseline design that is about a gigabyte in size.  They work
+all day, in parallel, each making their own customizations and tweaks
+to the design.  At the end of the day, they would like to merge their
+changes together into a single unified design.
+
+</p><p>The session extension facilitates this by recording all changes to
+both Alice's and Bob's databases and writing those changes into
+changeset or patchset files.  At the end of the day, Alice can send her
+changeset to Bob and Bob can "apply" it to his database.  The result (assuming
+there are no conflicts) is that Bob's database then contains both his
+changes and Alice's changes.  Likewise, Bob can send a changeset of
+his work over to Alice and she can apply his changes to her database.
+
+</p><p>In other words, the session extension provides a facility for
+SQLite database files that is similar to the unix
+<a href="https://en.wikipedia.org/wiki/Patch_(Unix)">patch</a> utility program,
+or to the "merge" capabilities of version control systems such
+as <a href="https://www.fossil-scm.org/">Fossil</a>, <a href="https://git-scm.com">Git</a>,
+or <a href="http://www.mercurial-scm.org/">Mercurial</a>.
+
+</p><h2 id="obtaining_the_session_extension"><span>1.2. </span>Obtaining the Session Extension</h2>
+
+<p> Since <a href="releaselog/3_13_0.html">version 3.13.0</a> (2016-05-18),
+the session extension has been included in the SQLite
+<a href="amalgamation.html">amalgamation</a> source distribution. By default, the session extension is
+disabled. To enable it, build with the following compiler switches:
+
+</p><div class="codeblock"><pre>-DSQLITE_ENABLE_SESSION -DSQLITE_ENABLE_PREUPDATE_HOOK
+</pre></div>
+
+<p> Or, if using the autoconf build system,
+pass the --enable-session option to the configure script.
+
+</p><h2 id="limitations"><span>1.3. </span>Limitations</h2>
+
+<ul>
+
+<li><p> Prior to SQLite version 3.17.0, the session extension only worked with
+        <a href="rowidtable.html">rowid tables</a>, not <a href="withoutrowid.html">WITHOUT ROWID</a> tables. As of 3.17.0, both
+        rowid and WITHOUT ROWID tables are supported. However, extra steps are
+        needed to record primary keys for WITHOUT ROWID table changes.
+
+</p></li><li><p> There is no support for <a href="vtab.html">virtual tables</a>. Changes to virtual tables are
+        not captured.
+
+</p></li><li><p> The session extension only works with tables that have a declared
+        PRIMARY KEY. The PRIMARY KEY of a table may be an INTEGER PRIMARY KEY
+        (rowid alias) or an external PRIMARY KEY.
+
+</p></li><li><p> SQLite allows <a href="nulls.html">NULL values</a> to be stored in
+        PRIMARY KEY columns. However, the session extension ignores all
+        such rows. No changes affecting rows with one or more NULL values
+        in PRIMARY KEY columns are recorded by the sessions module.
+</p></li></ul>
+
+<h1 id="concepts"><span>2. </span>Concepts</h1>
+
+<a name="changeset"></a>
+
+<h2 id="changesets_and_patchsets"><span>2.1. </span>Changesets and Patchsets</h2>
+<p> The sessions module revolves around creating and manipulating
+changesets. A changeset is a blob of data that encodes a series of
+changes to a database. Each change in a changeset is one of the
+following:
+
+</p><ul>
+  <li> <p>An <b>INSERT</b>. An INSERT change contains a single row to add to
+       a database table. The payload of the INSERT change consists of the
+       values for each field of the new row.
+
+  </p></li><li> <p>A <b>DELETE</b>. A DELETE change represents a row, identified by
+       its primary key values, to remove from a database table. The payload
+       of a DELETE change consists of the values for all fields of the
+       deleted row.
+
+  </p></li><li> <p>An <b>UPDATE</b>. An UPDATE change represents the modification of
+       one or more non-PRIMARY KEY fields of a single row within a database
+       table, identified by its PRIMARY KEY fields. The payload for an UPDATE
+       change consists of:
+   </p><ul>
+     <li> The PRIMARY KEY values identifying the modified row,
+     </li><li> The new values for each modified field of the row, and
+     </li><li> The original values for each modified field of the row.
+   </li></ul>
+       <p> An UPDATE change does not contain any information regarding
+       non-PRIMARY KEY fields that are not modified by the change. It is not
+       possible for an UPDATE change to specify modifications to PRIMARY
+       KEY fields.
+</p></li></ul>
+
+<p> A single changeset may contain changes that apply to more than one
+database table. For each table that the changeset includes at least one change
+for, it also encodes the following data:
+
+</p><ul>
+  <li> The name of the database table,
+  </li><li> The number of columns the table has, and
+  </li><li> Which of those columns are PRIMARY KEY columns.
+</li></ul>
+
+<p> Changesets may only be applied to databases that contain tables
+matching the above three criteria as stored in the changeset.
+
+</p><p> A patchset is similar to a changeset. It is slightly more compact than
+a changeset, but provides more limited conflict detection and resolution
+options (see the next section for details). The differences between a
+patchset and a changeset are that:
+
+</p><ul>
+  <li><p> For a <b>DELETE</b> change, the payload consists of the PRIMARY KEY
+          fields only. The original values of other fields are not stored as
+          part of a patchset.
+
+  </p></li><li><p> For an <b>UPDATE</b> change, the payload consists of the PRIMARY KEY
+          fields and the new values of modified fields only. The original
+          values of modified fields are not stored as part of a patchset.
+</p></li></ul>
+
+<h2 id="conflicts"><span>2.2. </span>Conflicts</h2>
+
+<p> When a changeset or patchset is applied to a database, an attempt is
+made to insert a new row for each INSERT change, remove a row for each
+DELETE change and modify a row for each UPDATE change. If the target
+database is in the same state as the original database that the changeset
+was recorded on, this is a simple matter. However, if the contents of the
+target database is not in exactly this state, conflicts can occur when
+applying the changeset or patchset.
+
+</p><p>When processing an <b>INSERT</b> change, the following conflicts can
+occur:
+
+</p><ul>
+  <li> The target database may already contain a row with the same PRIMARY
+       KEY values as specified by the INSERT change.
+
+  </li><li> Some other database constraint, for example a UNIQUE or CHECK
+       constraint, may be violated when the new row is inserted.
+</li></ul>
+
+<p>When processing a <b>DELETE</b> change, the following conflicts may be
+detected:
+
+</p><ul>
+  <li> The target database may contain no row with the specified PRIMARY
+       KEY values to delete.
+
+  </li><li> The target database may contain a row with the specified PRIMARY
+       KEY values, but the other fields may contain values that do not
+       match those stored as part of the changeset. This type of conflict
+       is not detected when using a patchset.
+</li></ul>
+
+<p>When processing an <b>UPDATE</b> change, the following conflicts may be
+detected:
+
+</p><ul>
+  <li> The target database may contain no row with the specified PRIMARY
+       KEY values to modify.
+
+  </li><li> The target database may contain a row with the specified PRIMARY
+       KEY values, but the current values of the fields that will be modified
+       by the change may not match the original values stored within the
+       changeset. This type of conflict is not detected when using a patchset.
+
+  </li><li> Some other database constraint, for example a UNIQUE or CHECK
+       constraint, may be violated when the row is updated.
+</li></ul>
+
+<p> Depending on the type of conflict, a sessions application has a variety
+of configurable options for dealing with conflicts, ranging from omitting the
+conflicting change, aborting the entire changeset application or applying
+the change despite the conflict. For details, refer to the documentation for
+the <a href="session/sqlite3changeset_apply.html">sqlite3changeset_apply()</a> API.
+
+</p><h2 id="changeset_construction"><span>2.3. </span>Changeset Construction</h2>
+
+<p> After a session object has been configured, it begins monitoring for
+changes to its configured tables. However, it does not record an entire
+change each time a row within the database is modified. Instead, it records
+just the PRIMARY KEY fields for each inserted row, and just the PRIMARY KEY
+and all original row values for any updated or deleted rows. If a row is
+modified more than once by a single session, no new information is recorded.
+
+</p><p> The other information required to create a changeset or patchset is
+read from the database file when <a href="session/sqlite3session_changeset.html">sqlite3session_changeset()</a> or
+<a href="session/sqlite3session_patchset.html">sqlite3session_patchset()</a> is called. Specifically,
+
+</p><ul>
+  <li> <p>For each primary key recorded as a result of an INSERT operation,
+       the sessions module checks if there is a row with a matching primary
+       key still in the table. If so, an INSERT change is added to the
+       changeset.
+
+  </p></li><li> <p>For each primary key recorded as a result of an UPDATE or DELETE
+       operation, the sessions module also checks for a row with a matching
+       primary key within the table. If one can be found, but one or more
+       of the non-PRIMARY KEY fields does not match the original recorded
+       value, an UPDATE is added to the changeset. Or, if there is no row
+       at all with the specified primary key, a DELETE is added to the
+       changeset. If the row does exist but none of the non-PRIMARY KEY
+       fields have been modified, no change is added to the changeset.
+</p></li></ul>
+
+<p> One implication of the above is that if a change is made and then
+unmade within a single session (for example if a row is inserted and then
+deleted again), the sessions module does not report any change at all. Or
+if a row is updated multiple times within the same session, all updates
+are coalesced into a single update within any changeset or patchset blob.
+
+</p><h1 id="using_the_session_extension"><span>3. </span>Using The Session Extension</h1>
+
+<p> This section provides examples that demonstrate how to use the sessions
+    extension.
+
+</p><h2 id="capturing_a_changeset"><span>3.1. </span>Capturing a Changeset</h2>
+
+<p> The example code below demonstrates the steps involved in capturing a
+changeset while executing SQL commands. In summary:
+
+</p><ol>
+  <li> <p>A session object (type sqlite3_session*) is created by making a
+          call to the <a href="session/sqlite3session_create.html">sqlite3session_create()</a> API function.
+
+       </p><p>A single session object monitors changes made to a single database
+          (i.e. "main", "temp" or an attached database) via a single
+          sqlite3* database handle.
+
+  </p></li><li> <p>The session object is configured with a set of tables to monitor
+          changes on.
+
+       </p><p> By default a session object does not monitor changes on any
+           database table. Before it does so it must be configured. There
+           are three ways to configure the set of tables to monitor changes
+           on:
+       </p><ul>
+         <li> By explicitly specifying tables using one call to
+              <a href="session/sqlite3session_attach.html">sqlite3session_attach()</a> for each table, or
+
+         </li><li> By specifying that all tables in the database should be monitored
+              for changes using a call to <a href="session/sqlite3session_attach.html">sqlite3session_attach()</a> with a
+              NULL argument, or
+
+         </li><li> By configuring a callback to be invoked the first time each table
+              is written to that indicates to the session module whether or
+              not changes on the table should be monitored.
+       </li></ul>
+        <p> The example code below uses the second of the methods enumerated
+            above - it monitors for changes on all database tables.
+
+  </p></li><li> <p> Changes are made to the database by executing SQL statements. The
+           session object records these changes.
+
+  </p></li><li> <p> A changeset blob is extracted from the session object using a call
+           to <a href="session/sqlite3session_changeset.html">sqlite3session_changeset()</a> (or, if using patchsets, a call to
+           the <a href="session/sqlite3session_patchset.html">sqlite3session_patchset()</a> function).
+
+  </p></li><li> <p> The session object is deleted using a call to the
+           <a href="session/sqlite3session_delete.html">sqlite3session_delete()</a> API function.
+
+       </p><p> It is not necessary to delete a session object after extracting
+           a changeset or patchset from it. It can be left attached to the
+           database handle and will continue monitoring for changes on the
+           configured tables as before. However, if
+           <a href="session/sqlite3session_changeset.html">sqlite3session_changeset()</a> or <a href="session/sqlite3session_patchset.html">sqlite3session_patchset()</a> is
+           called a second time on a session object, the changeset or patchset
+           will contain <em>all</em> changes that have taken place on the connection
+           since the session was created. In other words,
+           a session object is not reset or
+           zeroed by a call to sqlite3session_changeset() or
+           sqlite3session_patchset().

+</p><ol>
+  <li><p> The <a href="session/sqlite3changeset_start.html">sqlite3changeset_start()</a> API is called to create and

+<h1 id="extended_functionality"><span>4. </span>Extended Functionality</h1>
+
+<p> Most applications will only use the session module functionality described
+in the previous section. However, the following additional functionality is
+available for the use and manipulation of changeset and patchset blobs:
+
+</p><ul>
+  <li> <p>Two or more changeset/patchsets may be combined using the
+       <a href="session/sqlite3changeset_concat.html">sqlite3changeset_concat()</a> or <a href="session/changegroup.html">sqlite3_changegroup</a> interfaces.
+
+  </p></li><li> <p>A changeset may be "inverted" using the <a href="session/sqlite3changeset_invert.html">sqlite3changeset_invert()</a>
+       API function. An inverted changeset undoes the changes made by the
+       original. If changeset C<sup>+</sup> is the inverse of changeset C, then
+       applying C and then C<sup>+</sup> to a database should leave
+       the database unchanged.
+</p></li></ul><p align="center"><small><i>This page last modified on  <a href="https://sqlite.org/docsrc/honeypot" id="mtimelink"  data-href="https://sqlite.org/docsrc/finfo/pages/sessionintro.in?m=682990e565">2023-01-07 01:13:01</a> UTC </small></i></p>
