+ <dt>SQLITE_PREPARE_PERSISTENT</dt>
+<dd>The SQLITE_PREPARE_PERSISTENT flag is a hint to the query planner
+that the prepared statement will be retained for a long time and
+probably reused many times. Without this flag, <a href="../c3ref/prepare.html">sqlite3_prepare_v3()</a>
+and <a href="../c3ref/prepare.html">sqlite3_prepare16_v3()</a> assume that the prepared statement will
+be used just once or at most a few times and then destroyed using
+<a href="../c3ref/finalize.html">sqlite3_finalize()</a> relatively soon. The current implementation acts
+on this hint by avoiding the use of <a href="../malloc.html#lookaside">lookaside memory</a> so as not to
+deplete the limited store of lookaside memory. Future versions of
+SQLite may act on this hint differently.</p>

+<p><a name="sqlitepreparenormalize"></a>
+ <dt>SQLITE_PREPARE_NORMALIZE</dt>
+<dd>The SQLITE_PREPARE_NORMALIZE flag is a no-op. This flag used
+to be required for any prepared statement that wanted to use the
+<a href="../c3ref/expanded_sql.html">sqlite3_normalized_sql()</a> interface.  However, the
+<a href="../c3ref/expanded_sql.html">sqlite3_normalized_sql()</a> interface is now available to all
+prepared statements, regardless of whether or not they use this
+flag.</p>
+
+<p><a name="sqlitepreparenovtab"></a>
+ <dt>SQLITE_PREPARE_NO_VTAB</dt>
+<dd>The SQLITE_PREPARE_NO_VTAB flag causes the SQL compiler
+to return an error (error code SQLITE_ERROR) if the statement uses
+any virtual tables.
