Question

我正在尝试在laravel 5.3中执行一些原始查询。查询很简单，但我得到错误。

table name: users
columns: id|name|email|phone|created_at|updated_at

我的疑问：

SELECT created_at AS member_since, count(*) as row_count
FROM users
GROUP by MONTH(created_at);

当我在phpmyadmin上执行此查询时，此原始查询正常工作。但是当我使用laravel的数据库查询构建器执行此操作时，我会收到错误。

SQLSTATE[42000]: Syntax error or access violation: 1055 
'query.users.created_at' isn't in GROUP BY
SQLSTATE[42000]: Syntax error or access violation: 1055 
    'query.users.created_at' isn't in GROUP BY (SQL: select created_at AS 
    member_since from `users` group by MONTH(created_at))

这是我的控制器：

$users = DB::table('users')
            ->select(DB::raw('created_at AS member_since', 'count(*) AS row_count'))
            ->groupBy(DB::raw('MONTH(created_at)'))
            ->get();

return response()->json($users);

如果我错了，请纠正我。有没有更好的方法来执行原始查询？

首先，您需要了解您所获得的错误。这个问题就是https://stackoverflow.com/a/38551525/2474872

现在，考虑到这一点，你有两个选择

禁用only_full_group_by设置。

按照提供的指示进行操作通过错误消息：

  $users = DB::table('users')
    ->select(DB::raw('created_at AS member_since, count(*) AS row_count'))
    ->groupBy(DB::raw('MONTH(created_at)'), 'created_at')
    ->get();

groupBy(DB::raw('MONTH(created_at)'), 'created_at')也可以是groupBy(DB::raw('MONTH(created_at), created_at')
