问题描述

下面是我的代码,我无法解决此错误.任何帮助表示赞赏.我正在尝试更新数据库中的表.

Below is my code, I am not able to resolve this error. Any help is appreciated. I am trying to update a table in my database.

    public function updateUnit($params){
    $user = 'monil';
    $password = 'Masters123';
    $dbh = new \PDO('mysql:host=127.0.0.1;dbname=tcsdb', $user, $password);

    $task=array(':UnitCode'=>$params['UnitCode'],':UnitDescription'=>$params['UnitDescription']    ,
      ':UnitName'=>$params['UnitName'], ':UnitID'=>$params['UnitID']);
    echo $params['UnitID'];

    $sth = $dbh->prepare('UPDATE unit SET UnitCode = :UnitCode,'
        . 'UnitDescription = :UnitDescription,UnitName = :UnitName WHERE UnitId=:UnitId');
    $sth->execute($task);

    return true;
}

推荐答案

:UnitID != :UnitId

参数区分大小写.
