<para>
The <function>cubrid_insert_id</function> function retrieves the ID
generated for the AUTO_INCREMENT column which is updated by the previous
INSERT query. It returns 0 if the previous query does not generate new
rows, or FALSE on failure.
</para>
<note>
<para>
CUBRID supports AUTO_INCREMENT for more than one columns in a table. In
most cases, there will be a single AUTO_INCREMENT column in a table. If
there are multiple AUTO_INCREMENT columns, this function should not be
used even if it will return a value.
