JSON Where Clauses

Laravel offers helpers to query JSON columns for databases that support them.

Currently, MySQL 5.7+, PostgreSQL, SQL Server 2016, and SQLite 3.9.0 (using the JSON1 extension)

// To query a json column you can use the -> operator
$users = User::query()
            ->where('preferences->dining->meal', 'salad')
            ->get();
// You can check if a JSON array contains a set of values
$users = User::query()
            ->whereJsonContains('options->languages', [
                'en', 'de'
               ])
            ->get();
// You can also query by the length a JSON array
$users = User::query()
            ->whereJsonLength('options->languages', '>', 1)
            ->get();
