Question

I have an error in this query, when the query returns zero rows.

Error Number: 1064

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘-20,20’ at line 3

SELECT pl.name,pl.email FROM players pl JOIN players_bonus pl_b on pl.id = pl_b.id_player WHERE pl_b.id_bonus = 3 LIMIT -20,20


My method is:

    public function getPViews_num_rows($limit = array(0,20),$page_num = 1,$id) {
        $limit = "LIMIT {$limit[0]},{$limit[1]}";


    $sql = "SELECT pl.name,pl.email FROM players pl 
            JOIN players_bonus pl_b on pl.id = pl_b.id_player 
                WHERE pl_b.id_bonus = ? {$limit}";

    $where =  array($id);
    $query = $this->db->query ( $sql,$where );
    return $query->num_rows ();
}



I don't wanna do another query to count rows,before I do this query.

Thanks for the answers.

You can not specify negative value to LIMIT clause:

LIMIT -20,20 

It means you want to return 20 rows starting from -20 which is wrong.
