+#define SQLITE_SESSION_OBJCONFIG_ROWID 2
+</pre></blockquote><p>
+The following values may passed as the the 2nd parameter to
+sqlite3session_object_config().</p>
+
+<p><dt>SQLITE_SESSION_OBJCONFIG_SIZE <dd>
+ This option is used to set, clear or query the flag that enables
+ the <a href="../session/sqlite3session_changeset_size.html">sqlite3session_changeset_size()</a> API. Because it imposes some
+ computational overhead, this API is disabled by default. Argument
+ pArg must point to a value of type (int). If the value is initially
+ 0, then the sqlite3session_changeset_size() API is disabled. If it
+ is greater than 0, then the same API is enabled. Or, if the initial
+ value is less than zero, no change is made. In all cases the (int)
+ variable is set to 1 if the sqlite3session_changeset_size() API is
+ enabled following the current call, or 0 otherwise.</p>
+
+<p> It is an error (SQLITE_MISUSE) to attempt to modify this setting after
+ the first table has been attached to the session object.</p>
+
+<p><dt>SQLITE_SESSION_OBJCONFIG_ROWID <dd>
+ This option is used to set, clear or query the flag that enables
+ collection of data for tables with no explicit PRIMARY KEY.</p>
+
+<p> Normally, tables with no explicit PRIMARY KEY are simply ignored
+ by the sessions module. However, if this flag is set, it behaves
+ as if such tables have a column "_rowid_ INTEGER PRIMARY KEY" inserted
+ as their leftmost columns.</p>
+
+<p> It is an error (SQLITE_MISUSE) to attempt to modify this setting after
+ the first table has been attached to the session object.
