ifx_affected_rows
Popis
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.
