ifx_affected_rowsPodręcznik PHPPoprzedniNastępnyifx_affected_rows (PHP 3>= 3.0.3, PHP 4 >= 4.0.0)ifx_affected_rows -- Get number of rows affected by a queryDescriptionint 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. 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.
