+<h2>Last Insert Rowid</h2>
+</div>
+<blockquote><pre>
+sqlite3_int64 sqlite3_last_insert_rowid(sqlite3*);
+</pre></blockquote>
+<p>
+Each entry in most SQLite tables (except for <a href="../withoutrowid.html">WITHOUT ROWID</a> tables)
+has a unique 64-bit signed
+integer key called the <a href="../lang_createtable.html#rowid">"rowid"</a>. The rowid is always available
+as an undeclared column named ROWID, OID, or _ROWID_ as long as those
+names are not also used by explicitly declared columns. If
+the table has a column of type <a href="../lang_createtable.html#rowid">INTEGER PRIMARY KEY</a> then that column
+is another alias for the rowid.</p>
+
+<p>The sqlite3_last_insert_rowid(D) interface usually returns the <a href="../lang_createtable.html#rowid">rowid</a> of
+the most recent successful <a href="../lang_insert.html">INSERT</a> into a rowid table or <a href="../vtab.html">virtual table</a>
+on database connection D. Inserts into <a href="../withoutrowid.html">WITHOUT ROWID</a> tables are not
+recorded. If no successful <a href="../lang_insert.html">INSERT</a>s into rowid tables have ever occurred
+on the database connection D, then sqlite3_last_insert_rowid(D) returns
+zero.</p>
+
+<p>As well as being set automatically as rows are inserted into database
+tables, the value returned by this function may be set explicitly by
+<a href="../c3ref/set_last_insert_rowid.html">sqlite3_set_last_insert_rowid()</a></p>
+
+<p>Some virtual table implementations may INSERT rows into rowid tables as
+part of committing a transaction (e.g. to flush data accumulated in memory
+to disk). In this case subsequent calls to this function return the rowid
+associated with these internal INSERT operations, which leads to
+unintuitive results. Virtual table implementations that do write to rowid
+tables in this way can avoid this problem by restoring the original
+rowid value using <a href="../c3ref/set_last_insert_rowid.html">sqlite3_set_last_insert_rowid()</a> before returning
+control to the user.</p>
+
+<p>If an <a href="../lang_insert.html">INSERT</a> occurs within a trigger then this routine will
+return the <a href="../lang_createtable.html#rowid">rowid</a> of the inserted row as long as the trigger is
+running. Once the trigger program ends, the value returned
+by this routine reverts to what it was before the trigger was fired.</p>
+
+<p>An <a href="../lang_insert.html">INSERT</a> that fails due to a constraint violation is not a
+successful <a href="../lang_insert.html">INSERT</a> and does not change the value returned by this
+routine. Thus INSERT OR FAIL, INSERT OR IGNORE, INSERT OR ROLLBACK,
+and INSERT OR ABORT make no changes to the return value of this
+routine when their insertion fails. When INSERT OR REPLACE
+encounters a constraint violation, it does not fail. The
+INSERT continues to completion after deleting rows that caused
+the constraint problem so INSERT OR REPLACE will always change
+the return value of this interface.</p>
+
+<p>For the purposes of this routine, an <a href="../lang_insert.html">INSERT</a> is considered to
+be successful even if it is subsequently rolled back.</p>
+
+<p>This function is accessible to SQL statements via the
+<a href="../lang_corefunc.html#last_insert_rowid">last_insert_rowid() SQL function</a>.</p>
+
+<p>If a separate thread performs a new <a href="../lang_insert.html">INSERT</a> on the same
+database connection while the <a href="../c3ref/last_insert_rowid.html">sqlite3_last_insert_rowid()</a>
+function is running and thus changes the last insert <a href="../lang_createtable.html#rowid">rowid</a>,
+then the value returned by <a href="../c3ref/last_insert_rowid.html">sqlite3_last_insert_rowid()</a> is
+unpredictable and might not equal either the old or the new
+last insert <a href="../lang_createtable.html#rowid">rowid</a>.
