How do you wrap Laravel Eloquent ORM query scopes in parentheses when chaining?

Question

In Eloquent, I\'d like to generate this query:

SELECT * FROM table WHERE a=1 AND ( b=2 OR c=3 );

But I seem to be generating this query instead

Answer 1

You can generate parentheses by passing a callback function to where().

Model::where('a',1)->where(function($query) {
    $query->where('b', 2)->orWhere('c',3);
})->get();
