PHP 忒聊 綴豖 ヶ輛 ifx_affected_rows (PHP 3 = 3.0.3, PHP 4) Description 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. See also: ifx_num_rows() 瞰赽 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");} 綴豖 れ萸 ヶ輛 Informix functions 奻珨撰 ifx_blobinfile_mode
