# ifx_affected_rows

ifx_affected_rows -- Get number of rows affected by a query

## Description

`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.

See also: ifx_num_rows()

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");
    }
