無法使用限制從數據庫中選擇數據

Question

我使用PHP MySQL這樣選擇數據，沒有錯誤。

$sql = "SELECT pd_id, pd_name, pd_price, pd_qty 
        FROM tbl_product ORDER BY pd_id DESC";

我只選擇6行。 所以，我這樣編輯代碼。

$sql = "SELECT pd_id, pd_name, pd_price, pd_qty 
        FROM tbl_product ORDER BY pd_id DESC LIMIT 6";

然后，它顯示這樣的錯誤。

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'LIMIT 0, 6' at line 2

如何從MySQL選擇數據6行

Answer 1

試試這個

$sql = "SELECT pd_id, pd_name, pd_price, pd_qty 
        FROM tbl_product ORDER BY pd_id DESC LIMIT 0, 6 ";

Answer 2

SELECT TYPE FROM stuff ORDER BY STUFF_ID DESC LIMIT 6

用上面使用的列替換查詢
