In this post i will guide how to fix SQLSTATE[42000]: Syntax error or access violation: 1055 isn’t in GROUP BY Error.
Actually It’s not a Laravel Error. This is MySQL Error and which comes in your MySQL DB SQL_MODE have ONLY_FULL_GROUP_BY Value.
In few Weeks before i search this Error in Internet i got following Solution.
Open config/database.php File. in the connections => mysql turn strict value to false. So do it like as bellow:
'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,
],
Now access your Laravel Application its Working.
I thing this is Not a right solution. If you are change ‘strict’ value to false. It will remove following SQL modes.
ONLY_FULL_GROUP_BY STRICT_TRANS_TABLES NO_ZERO_IN_DATE NO_ZERO_DATE ERROR_FOR_DIVISION_BY_ZERO NO_AUTO_CREATE_USER NO_ENGINE_SUBSTITUTION
We got this error is just because of ONLY_FULL_GROUP_BY SQL_MODE.
Laravel offers we can define our SQL modes with every DB connection in our configuration file. So, i turn Mysql strict to true and specify SQL_MODE like below
'mysql' => [
'driver' => 'mysql',
'host' => 'HOST_NAME',
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'DB_NAME'),
'username' => 'USER_NAME',
'password' => 'PASSWORD',
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
'modes' => [
'STRICT_TRANS_TABLES',
'NO_ZERO_IN_DATE',
'NO_ZERO_DATE',
'ERROR_FOR_DIVISION_BY_ZERO',
'NO_AUTO_CREATE_USER',
'NO_ENGINE_SUBSTITUTION'
],
]
Now works Fine. Happy Coding…
