LEARN ABOUT PHP
ifx_affected_rows
IFX_AFFECTED_ROWS(3) 1 IFX_AFFECTED_ROWS(3)
ifx_affected_rows - Get number of rows affected by a query
SYNOPSIS
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 />
");
}
?>
