How can I use Laravel's query builder for advanced queries?

You can use Laravel's query builder to perform complex queries by chaining methods like where, join, and groupBy. What specific advanced query are you looking to create?

I want to perform a query that includes multiple joins and conditions.

You can achieve that by using the join method for each table you want to join. For example:

DB::table('users')
    ->join('posts', 'users.id', '=', 'posts.user_id')
    ->join('comments', 'posts.id', '=', 'comments.post_id')
    ->where('users.active', 1)
    ->where('comments.approved', 1)
    ->select('users.*', 'posts.title', 'comments.body')
    ->get();

This will give you users with their active posts and approved comments.

What if I want to add pagination to this query?

You can use the paginate method instead of get. Just replace the last line with:

->paginate(10);

This will return 10 results per page.
