Resolving SQL_MODE=ONLY_FULL_GROUP_BY Conflict in Laravel Eloquent

When using Eloquent to perform a group-by query, you may encounter an error related to incompatible settings for sql_mode=only_full_group_by. This error can occur when non-aggregated columns are included in the SELECT list that are not part of the GROUP BY clause.

To solve this issue, you can disable the strict MySQL mode by setting the following in your database configuration file:

'connections' => [
    'mysql' => [
        'strict' => false,
    ]
]

By setting 'strict' to false, you are allowing MySQL to behave as if it were running in MySQL 5.6 mode, which does not enforce the strict grouping rules imposed by sql_mode=only_full_group_by.

Alternatively, you can modify your Eloquent query to ensure that all columns in the SELECT list are either aggregated or included in the GROUP BY clause. For example, you could use the 'raw' method to add the necessary aggregation:

$products = Product::where('status', 1)
    ->where('stock', '>', 0)
    ->where('category_id', '=', $category_id)
    ->groupBy('store_id')
    ->orderBy('updated_at', 'desc')
    ->selectRaw('*, COUNT(*) AS total_products')
    ->take(4)
    ->get();
