PDO Mysql Syntax error 1064 [closed]

Answer 1

This seems to be a php bug : PDO ignores the PARAM_INT constant and use the $limit and $limitvalue variables as string. Which are quoted in the query when bound.

Try using :

$sql->bindParam(1, (int)$limitvalue, PDO::PARAM_INT);
$sql->bindParam(2, (int)$limit, PDO::PARAM_INT);

To force the variables type to int.

Answer 2

I don't think that the first parameter of the limit in the sql can be NULL. If you just want the first 10 records then use LIMIT 10.
