yii2 使用 dblib 驱动 SQLSTATE[HY000]: General error: 20018 Invalid object name t_user

Question

我在我的项目中使用了 dblib 驱动程序， 但执行查询异常

Database Exception – yii\db\Exception
SQLSTATE[HY000]: General error: 20018 Invalid object name 't_user'. [20018] (severity 16) [select top 10 * from t_user]
The SQL being executed was: select top 10 * from t_user
Error Info: Array
(
    [0] => HY000
    [1] => 20018
    [2] => Invalid object name 't_user'. [20018] (severity 16) [select top 10 * from t_user]
    [3] => -1
    [4] => 16
)
↵
Caused by: PDOException
SQLSTATE[HY000]: General error: 20018 Invalid object name 't_user'. [20018] (severity 16) [select top 10 * from t_user]

如果我使用原生 PHP 就可以了

<?php

 $dbh = new PDO("dblib:host=;dbname=","","");

$query = $dbh->prepare("SELECT top 1 * from t_user");
$query->execute();
while($row = $query->fetch()){
        print_r($row);
}

我安装 freetds php_dblib

yii2 配置 [使用 yii2 basic 2.0.x]

 <?php

return [
    'class' => 'yii\db\Connection', // yii connection
    'dsn' => 'dblib:host=;database=', // this is dblib
    'username' => '', // user name 
    'password' => '', // password
    'charset' => 'utf8',
];

我不知道如何解决这个问题。 大牛求帮忙~

如前所述，“用户”是一个保留字。使用保留字作为标识符是个坏主意 - 您确实需要养成良好的习惯，而不是更多的坏习惯。

您应该更改您的表格的名称，以便它不需要被分隔。通过阅读regular identifiers 的文档来学习。但您可以使用以下内容：

select <columns of interest> from dbo.[user] order by <whatever>:

注意良好的习惯 - 模式限定对象名称，指定您需要的列，如果需要，应用 ORDER BY 子句。
