Question

当试图在laravel上运行php artisan迁移时，我遇到了错误

In database.php line 79:
Undefined class constant 'SQLSRV_ENCODING_SYSTEM'

我已经安装了sql驱动程序等，但不确定如何解决此问题

database.php文件

'sqlsrv' => [
        'driver' => 'sqlsrv',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '1433'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'charset' => 'utf8',
        'prefix' => '',
        'options' => [PDO::SQLSRV_ENCODING_SYSTEM => false], // Used for MSSQL encoding
    ],

Answer 1

说明：

PDO::SQLSRV_ENCODING_SYSTEM是PDO_SQLSRV Driver Constant，而不是选项名称。您应该在选项中使用PDO::SQLSRV_ATTR_ENCODING => PDO::SQLSRV_ENCODING_SYSTEM。请记住，此选项是Microsoft SQL Server专用的SQL Server驱动程序专用驱动程序属性（PDO::SQLSRV_ATTR_ENCODING和PDO::SQLSRV_ATTR_DIRECT_QUERY中的一个）。

<?php

...
'sqlsrv' => [
    'driver' => 'sqlsrv',
    'host' => env('DB_HOST', 'localhost'),
    'port' => env('DB_PORT', '1433'),
    'database' => env('DB_DATABASE', 'forge'),
    'username' => env('DB_USERNAME', 'forge'),
    'password' => env('DB_PASSWORD', ''),
    'charset' => 'utf8',
    'prefix' => '',
    'options' => [PDO::SQLSRV_ATTR_ENCODING => PDO::SQLSRV_ENCODING_SYSTEM]
],

...
?>

注释：

文档：Microsoft SQL Server Functions (PDO_SQLSRV)和Constants (Microsoft Drivers for PHP for SQL Server)。

未定义的类常量'SQLSRV_ENCODING_SYSTEM'
