解決laravel出現Syntax error or access violation: 1055 '***' isn't in GROUP BY

laravel 5.3 以后默認開啟 mysql嚴格模式(strict)
在mysql在嚴格模式下, 並且開啟了ONLY_FULL_GROUP_BY的情況下,
group by 的字段沒有出現在 select 的語句中會報錯.關閉了嚴格模式就不會報錯.

如下Demo

public static function orders($phase) { return self::select(DB::raw("SUM(orders) as orders"),"type","users_id","name") ->groupBy("type","name") ->where("phase",$phase) ->get(); }

會出現如下錯誤，當然*號內的內容是不同的

Syntax error or access violation: 1055 '***' isn't in GROUP BY

解決辦法

laravel出現上述錯誤是sql_mode設置導致的問題,修改config/database.php配置文件的strict => false即可關閉了嚴格模式:

'mysql' => [ 'driver' => 'mysql', 'host' => env('DB_HOST', 'localhost'), 'port' => env('DB_PORT', '3306'), 'database' => env('DB_DATABASE', 'forge'), 'username' => env('DB_USERNAME', 'forge'), 'password' => env('DB_PASSWORD', ''), 'charset' => 'utf8', 'collation' => 'utf8_unicode_ci', 'prefix' => '', 'strict' => false, 'engine' => null, ],
