【问题描述】：

我正在使用以下查询：

$data = DB::table('developers')
->select('iDeveloperId', 'vFirstName', 'vLastName', 'iGroupId')
->groupBy('vFirstName')
->get();

但我收到如下错误：

Warning: Creating default object from empty value in /var/www/html/laravel_demo/query_builder/db_config.php on line 40

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'hbmp_hims.developers.iDeveloperId' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by' in /var/www/html/laravel_demo/query_builder/illuminate/vendor/illuminate/database/Connection.php:333 Stack trace: #0 /var/www/html/laravel_demo/query_builder/illuminate/vendor/illuminate/database/Connection.php(333): PDO->prepare('select `iDevelo...') #1 /var/www/html/laravel_demo/query_builder/illuminate/vendor/illuminate/database/Connection.php(662): Illuminate\Database\Connection->Illuminate\Database\closure(Object(Illuminate\Database\mysqlConnection), 'select `iDevelo...', Array) #2 /var/www/html/laravel_demo/query_builder/illuminate/vendor/illuminate/database/Connection.php(629): Illuminate\Database\Connection->runQueryCallback('select `iDevelo...', Array, O in /var/www/html/laravel_demo/query_builder/illuminate/vendor/illuminate/database/Connection.php on line 669

我犯了什么错误。

注意：使用iDeveloperId代替vFirstName时有效

提前致谢...

【参考方案1】：

尝试在您的 MySQL 数据库中禁用 Full group by。

SET sql_mode = ''

【讨论】：

我试过了，但我的 Mysql 数据库显示以下模式 ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_AUTO_CRE...

@@sql_mode ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_AUTO_CRE... 解决办法是什么，注意：我的数据库是5.7版本有什么问题

@GattiSrinivas 解决方案是答案中写的：禁用完整组

SET sql_mode = '' 在数据库中执行成功但sql_mode保持不变

【参考方案2】：

我得到了答案

SET GLOBAL sql_mode = '';
