by the input statement handle is not an UPDATE, INSERT, or DELETE statement,
or if it is not processed successfully, then the function sets the contents
of <em>pcrow</em> to 0.</p>
<p>Any rows in other tables that might have been
affected by the statement (for example, cascading deletes) are not included
in the count.</p>
