(PHP 4, PHP <=5.2.0)
Get number of rows affected by a query
int ifx_affected_rows ( resource $result_id )
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. The database server can never return the actual number of rows that will be returned by a SELECT because it has not even begun fetching them at this stage (just after the "PREPARE" when the optimizer has determined the query plan).
Useful after ifx_prepare() to limit queries to reasonable result sets.
Parameters:
result_id
A valid result id returned by ifx_query() or ifx_prepare().
Returns:
Returns the number of rows as an integer.
Examples:
Informix affected rows
<?php $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"); } ?>
