一、查看php 是否安装了 sqlsrv 扩展, 使用命令 php -m

二、如果没安装会报错 laravel could not find driver sqlsrv

三、下载安装 php 对应的sqlsrv 扩展  到目录  php 的 ext 目录下

链接地址:https://docs.microsoft.com/zh-cn/sql/connect/php/download-drivers-php-sql-server?view=sql-server-ver15

四、更改php.ini,重启apache 或者 nginx

    extension=php_sqlsrv_73_nts_x64.dll    
    extension=php_pdo_sqlsrv_73_nts_x64.dll

五、配置env

    YY_DB_CONNECTION=sqlsrv    
    YY_DB_PORT=1433
    YY_DB_HOST=192.168.101.173
    YY_DB_DATABASE=U8CLOUD
    YY_DB_USERNAME=sa
    YY_DB_PASSWORD=sa123456

六、配置config目录下的 database

    'connections' => [    
    'sqlsrv_yongyou' => [
          'driver' => 'sqlsrv',
          'host' => env('YY_DB_HOST', 'localhost'),
          'port' => env('YY_DB_PORT', '1433'),
          'database' => env('YY_DB_DATABASE', ''),
          'username' => env('YY_DB_USERNAME', ''),
          'password' => env('YY_DB_PASSWORD', ''),
          'charset' => 'utf8',
          'prefix' => env('YY_DB_TABLEPREFIX',''),
          'prefix_indexes' => true,
       ],
    ],

七、新建sqlserver 表对应的Model,选择对应的connection 和对应的表

    php artisan make:model Model/YongYou/BdCubasdoc
    <?php    
    namespace App\Model\YongYou;
    use Illuminate\Database\Eloquent\Model;
    class BdCubasdoc extends Model
    {
        //
         protected $connection = 'sqlsrv_yongyou';
         protected $table = "bd_cubasdoc";
    }

八、查询测试sql server 数据

    public function handle()    
    {  
      $rows = BdCubasdoc::where('custname', '=', '海门药业有限公司')->get()->toArray();
      dump($rows);
    }

九、如果报以下错误、说明电脑需要安装 ODBC 驱动程序

 Illuminate\Database\QueryException  : SQLSTATE[IMSSP]: This extension requires the Microsoft ODBC Driver for SQL Server to communicate with SQL Server. Access the following UR

L to download the ODBC Driver for SQL Server for x64: https://go.microsoft.com/fwlink/?LinkId=163712
