Question

以下是我用于管理足球设备和结果管理网站的代码。我遇到的问题是删除语法（我想我的[ID]混淆了）。我有其他一切正常。

如果我尝试删除第一行，则会显示以下错误：

错误删除[您的SQL语法中有错误;检查与MySQL服务器版本对应的手册，以便在第1行的'standings_id ='0''附近使用正确的语法。

SQL表中使用的字段如下：

standings_id, team_name, goals_for, goals_away, goal_difference, points

代码：

<?
$objConnect =mysql_connect('localhost', 'username', 'password') or die(mysql_error());
$objDB = mysql_select_db("database");

if($_POST["hdnCmd"] == "Add")
