Question

您好我一直在尝试更新我的表的状态，但我可以弄清楚为什么这个aint工作，它显示错误信息所以状态不更新

     $uid = $_GET["uid"]; 

     $query=$db->query("UPDATE INTO users SET status = 0 WHERE uid = '$uid'");    
    if ($query){
     echo "ok";
}
    else 
    {
        echo "error.";
    }

Answer 1

它不应该是update into

UPDATE users SET status = 0 WHERE uid = '$uid'

Answer 2

您的查询必须是您正在混合插入和更新查询

UPDATE users SET status = 0 WHERE uid = '$uid'

您需要了解差异

UPDATE

UPDATE table_name
SET column1=value, column2=value2,...
WHERE some_column=some_value

INSERT

INSERT INTO table_name ( field1, field2,...fieldN )
VALUES ( value1, value2,...valueN );

Answer 3

只需删除INTO，就无法{i} UPDATE查询。

$query=$db->query("UPDATE users SET status = 0 WHERE uid = '$uid'");

如何用php和mysql更新表
