MYSQL语法错误1064

Question

我只是不明白为什么从这个查询中收到错误 1064

//prep the data for database use
$manufacturer_id = $_GET['id'];
$manufacturer_display_name = mysql_prep($_POST['manufacturer_display_name']);
$manufacturer_name = mysql_prep($_POST['manufacturer_name']);


$query = "UPDATE IT_manufacturer SET
        manufacturer_name = '{$manufacturer_name}',
        manufacturer_display_name = '{$manufacturer_display_name}',
        WHERE manufacturer_id = {$manufacturer_id}
        ";

$result = mysql_query($query, $connection);
confirm_query ($result);

如果我回显变量 $manufacturer_name、$manufacturer_display_name、$manufacturer_id 它们都有值，但我收到此错误

无法执行查询您的 SQL 语法中有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 4 行“WHEREManufacturer_id = 1”附近使用的正确语法错误号 1064

任何帮助

Answer 1

删除 where 之前的逗号，

    $query = "UPDATE IT_manufacturer SET manufacturer_name = '{$manufacturer_name}',
                 manufacturer_display_name = '{$manufacturer_display_name}' 
                 WHERE manufacturer_id = {$manufacturer_id} ";

逗号只能分隔正在设置的不同变量，而不是来自 where 的设置。

Answer 2

删除 where 之前的逗号：

'{$manufacturer_display_name}', WHERE manufacturer_id
