问题 Im currently scratching my head at how to implement SQL_CALC_FOUND_ROWS with prepared statements. I'm writing a pagination class and obviously i want to add LIMIT to the query but also find what the total number of rows would be. Heres an example from the class in question. $query="select SQL_CALC_FOUND_ROWS id,title,location,salary,employer from jobs where region=38 limit 0,3"; if($stmt = $connection->prepare($query)) { $stmt->execute()or die($connection->error); //execute query $stmt->bind

I try to avoid doing Count( ) because of performance issue. (i.e. SELECT COUNT( ) FROM Users) If I run the followings in phpMyAdmin, it is ok: SELECT SQL_CALC_FOUND_ROWS * FROM Users; SELECT FOUND_ROWS(); It will return # of rows. i.e. # of Users. However, if I run in in PHP, I cannot do this: $query = 'SELECT SQL_CALC_FOUND_ROWS * FROM Users; SELECT FOUND_ROWS(); '; mysql_query($query); It seems like PHP doesn't like to have two queries passing in. So, how can I do that? SQL_CALC_FOUND_ROWS is only useful if you're using a LIMIT clause, but still want to know how many rows would've been found
