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.

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 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.

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. +</p><p>See also lists of + <a href="objlist.html">Objects</a>, + <a href="constlist.html">Constants</a>, and + <a href="funclist.html">Functions</a>.</p> + diff --git a/www/session/sqlite3session_changeset_size.html b/www/session/sqlite3session_changeset_size.html new file mode 100644 index 0000000..719df80 --- /dev/null +++ b/www/session/sqlite3session_changeset_size.html @@ -0,0 +1,133 @@ +<!DOCTYPE html> +<html><head> +<meta name="viewport" content="width=device-width, initial-scale=1.0"> +<meta http-equiv="content-type" content="text/html; charset=UTF-8"> +<link href="../sqlite.css" rel="stylesheet"> +<title>Return An Upper-limit For The Size Of The Changeset</title> +<!-- path=../ --> +</head> +<body> +<div class=nosearch> +<a href="../index.html"> +<img class="logo" src="../images/sqlite370_banner.gif" alt="SQLite" border="0"> +</a> +<div><!-- IE hack to prevent disappearing logo --></div> +<div class="tagline desktoponly"> +Small.
