Answer 1

Your mysql version is 5.7+, so check this reference

MySQL 5.7.5 and up implements detection of functional dependence. If the ONLY_FULL_GROUP_BY SQL mode is enabled (which it is by default), MySQL rejects queries for which the select list

Solution 1:

Check the config/database.php, if your mysql configuration strict => true , you need to disabled the ONLY_FULL_GROUP_BY , add modes like this:

        'mysql' => [
            'driver' => 'mysql',
            ...
            'strict' => true,
            'engine' => null,
            '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'
           ],
        ],

PS: set strict => false can work too, but disabling it make your app unsecured.

Solution 2:

Use ANY_VALUE :

This function is useful for GROUP BY queries when the ONLY_FULL_GROUP_BY SQL mode is enabled, for cases when MySQL rejects a query that you know is valid for reasons that MySQL cannot determine. The function return value and type are the same as the return value and type of its argument, but the function result is not checked for the ONLY_FULL_GROUP_BY SQL mode.

$dataP = DB::table('chantiers')
         ->leftJoin('pointages','pointages.chantier_id','chantiers.id')
          ->selectRaw('COALESCE(SUM(pointages.sold),0) AS sold, ANY_VALUE(chantiers.chantier) AS chantier, pointages.chantier_id')
          ->groupBy('pointages.chantier_id')
          ->get();

PS: ANY_VALUE does not exist on MariaDB .

Answer 2

Group by only possible on select field

As per your above query, you don't add group by field in the select field that why Laravel gave you the error.

So can you please try following which will work for you

$dataP = DB::table('chantiers')
         ->leftJoin('pointages','pointages.chantier_id','chantiers.id')
          ->selectRaw('COALESCE(SUM(pointages.sold),0) as sold,chantiers.chantier,pointages.chantier_id')
          ->groupBy('pointages.chantier_id')
          ->get();

Hope you get your require answer
