SQLSTATE[42000]:语法错误或访问冲突:1064(之前的答案没有帮助)

我试图修复这个查询，但由于某种原因，它抛出错误。我应该做什么改变?

$statement=$conn->prepare("SELECT p.productid AS productid,
                                  p.productname AS productname,
                                  t.itemid AS itemid,t.amount AS amount,
                                  t.is_completed AS is_completed,
                                  t.id AS recordid 
                           FROM products p,temporder t 
                           where p.productid=t.itemid AND is_completed = 0 
                           LIMIT 0, 30 AND t.email = ?");
$statement->execute(array($_SESSION['email']));
$rows=$statement->rowCount();//get no. of rows
$statement->setFetchMode(PDO::FETCH_ASSOC);

错误:
