The easiest way to find out how many rows a query will return is to use the COUNT function in SQL.
For operations that aren't queries (such as INSERTs, UPDATEs, and DELETEs), the do method returns the number of rows affected, -1 when it can't determine the right value, or else undef in case of failure.

ifx_affected_rows
IFX_AFFECTED_ROWS(3) 1 IFX_AFFECTED_ROWS(3)ifx_affected_rows - Get number of rows affected by a querySYNOPSIS
int ifx_affected_rows (resource $result_id)
DESCRIPTION
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(3) to limit queries to reasonable result sets.
PARAMETERS
o $result_id
- A valid result id returned by ifx_query(3) or ifx_prepare(3).
RETURN VALUES
Returns the number of rows as an integer.
EXAMPLES
Example #1
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)
<br />", $rowcount);
die ("Please restrict your query<br />
");
}
?>
