Laravel : Syntax error or access violation: 1055 Error

Laravel: Syntax error or access violation: 1055 Error

Are you encountering a "Syntax error or access violation: 1055 Error" when using Laravel's whereIn and groupBy methods in the same query? Don't worry, you're not alone! This common issue can be frustrating, but we're here to help you understand what's going on and provide easy solutions to fix the problem.

Understanding the Error

The error message you received may look something like this:

SQLSTATE[42000]: Syntax error or access violation: 1055 'sbrtpt.loading.id' isn't in GROUP BY (SQL: select * from loading where id in (14, 15, 16) group by vehicle_no)

This error occurs because of a strict mode in MySQL. By default, MySQL only allows columns that are present in the GROUP BY clause or used in aggregate functions (e.g., COUNT, MAX, MIN, etc.) to be selected in the query result. However, Laravel's whereIn method adds additional columns to the query, causing the error.

Solution: Disable Strict Mode

One way to solve this issue is by disabling the strict mode in MySQL. You can do this by following these steps:

1. Open your Laravel project's .env file.

2. Look for the line that starts with DB_CONNECTION= and make sure it is set to mysql.

3. Add the following line below it: DB_STRICT_MODE=false.

4. Save the file and restart your web server.

By disabling the strict mode, MySQL will no longer enforce the "only columns in GROUP BY or aggregate functions" rule, eliminating the error.

Solution: Use the ANY_VALUE Function

Another solution is to use the ANY_VALUE function in your query. This function allows you to select non-grouped columns while still satisfying MySQL's strict mode requirements. Here's an example:

$loadids = explode("#@*", $reciptdet->loading_id);
$loadingdatas = DB::table('loading')
    ->selectRaw('ANY_VALUE(id) as id, vehicle_no')
    ->groupBy('vehicle_no')
    ->whereIn('id', $loadids)
    ->get();

By selecting ANY_VALUE(id) instead of just id, you're telling MySQL to use any value for the id column within each group. This circumvents the strict mode restriction and resolves the error.
