简单DELETE php pdo查询

Question

我想删除数据，但有多个条件，所以我写这个：

$STH = $DBH->prepare("DELETE FROM track_aktivnosti WHERE (ID,ajdi), VALUES(:id,:ajdi)");

            $STH->bindParam(':id', $_POST['vrednostid']);
        $STH->bindParam(':ajdi', $_POST['ajdi']);

但我有错误是声明？我需要改变什么？

Answer 1

您的SQL语法错误。它应该是

$STH = $DBH->prepare("DELETE FROM track_aktivnosti WHERE ID=:id AND ajdi=:ajdi");
$STH->bindParam(':id', $_POST['vrednostid']);
$STH->bindParam(':ajdi', $_POST['ajdi']);
$STH->execute();

Answer 2

$stmt = $dbh->prepare("DELETE FROM track_aktivnosti WHERE (ID = ? and ajdi = ?)");
$stmt->execute(array($_POST['vrednostid'],$_POST['ajdi']));
