int ifx_affected_rows
(int result_id);result_id is a valid result id returned by ifx_query() or ifx_prepare().
Returns the number of rows affected by a query associated with result_id.
For inserts, updates and deletes the number is the real number (sqlerrd[2]) of affected rows. For selects it is an estimate (sqlerrd[0]). Don't rely on it.
Useful after ifx_prepare() to limit queries to reasonable result sets.

Example 1. Informix affected rows $rid = ifx_prepare ("select * from emp where name like " . $name, $connid); if (! $rid) { ... error ... } $rowcount = ifx_affected_rows ($rid); if ($rowcount > 1000) { printf ("Too many rows in result set (%d)\n<br>", $rowcount); die ("Please restrict your query<br>\n"); } |
