+<a href="../session/intro.html"><h2>Session Module C Interface</h2></a><h2>Add A Changeset To A Changegroup</h2><blockquote><pre>int sqlite3changegroup_add(sqlite3_changegroup*, int nData, void *pData);
+</pre></blockquote><p>
+Add all changes within the changeset (or patchset) in buffer pData (size
+nData bytes) to the changegroup. </p>
+
+<p>If the buffer contains a patchset, then all prior calls to this function
+on the same changegroup object must also have specified patchsets. Or, if
+the buffer contains a changeset, so must have the earlier calls to this
+function. Otherwise, SQLITE_ERROR is returned and no changes are added
+to the changegroup.</p>
+
+<p>Rows within the changeset and changegroup are identified by the values in
+their PRIMARY KEY columns. A change in the changeset is considered to
+apply to the same row as a change already present in the changegroup if
+the two rows have the same primary key.</p>
+
+<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.
