语法错误或访问冲突:group by中的1055表达式#17 [英] Syntax error or access violation: 1055 Expression #17 in group by

问题描述

我在laravel 5.3中使用group尝试查询.我抓到

I tried a query using group in laravel 5.3.I caught

SQLSTATE [42000]:语法错误或访问冲突:1055 SELECT列表的表达式#17不在GROUP BY子句中，并且包含未聚合的列"testtravel.country.name"，该列在功能上不依赖于GROUP BY子句中的列；这与sql_mode = only_full_group_by(SQL:

SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #17 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'testtravel.country.name' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by (SQL:

select  `travel_request`.*, `travel_request`.`id` as `travel_id`,
        `department`.`name` as `dept_name`, `users`.`firstname` as `approver_name`,
        `travel_purpose`.`purpose`, `country`.`name` as `country_name`,
        `traveling_details`.`from_date`, `traveling_details`.`to_date`,
        `travel_request_status`.`status`
    from  `travel_request`
    inner join  `department`  ON `travel_request`.`department_id` = `department`.`id`
    inner join  `users`  ON `travel_request`.`approver_id` = `users`.`id`
    inner join  `travel_purpose`  ON `travel_request`.`travel_purpose_id` = `travel_purpose`.`id`
    inner join  `traveling_details`  ON `travel_request`.`id` = `traveling_details`.`travel_request_id`
    inner join  `country`  ON `country`.`id` = `traveling_details`.`country_id`
    inner join  `travel_request_status`  ON `travel_request`.`status_id` = `travel_request_status`.`id`
    where  `travel_request`.`approver_id` = 187
      and  `travel_request`.`status_id` != 4
    group by  `travel_request`.`id`
    limit  2 offset 0)

我复制了查询并在sql中运行.它在mysql中运行良好.我尝试过

I copied the query and run in sql.Its is working well in mysql.I tried as

 $users = DB::table('travel_request')
        ->join('department', 'travel_request.department_id', '=', 'department.id')
        ->join('users', 'travel_request.approver_id', '=', 'users.id')
        ->join('travel_purpose', 'travel_request.travel_purpose_id', '=', 'travel_purpose.id')
        ->join('traveling_details', 'travel_request.id','=','traveling_details.travel_request_id' )
        ->join('country','country.id', '=', 'traveling_details.country_id')
        ->join('travel_request_status','travel_request.status_id', '=', 'travel_request_status.id')
        ->select('travel_request.*', 'travel_request.id as travel_id','department.name as dept_name','users.firstname as approver_name','travel_purpose.purpose','country.name as country_name','traveling_details.from_date','traveling_details.to_date','travel_request_status.status')->where('travel_request.approver_id', $user_id)->where('travel_request.status_id','!=','4')->GROUPBY ('travel_request.id')->paginate(2);

解决了

但是要禁用此功能，只需转到config/database.php并更改严格标志

However to disabled this just go to config/database.php and change strict flag

'mysql' => [
            .
            .
            .
            'strict' => false,
            //'strict' => true,
            .
            .
        ],

推荐答案

打开您的config/database.php文件并按以下方式更改mysql配置数组:

Open your config/database.php file and change mysql configuration array as following:

来自'strict' => true

到'strict' => false
