AI translates the explanation and quiz text while preserving code and answer scoring.

The Query Builder (DB::table('users')) provides a fluent, database-agnostic interface for building SQL queries without writing raw SQL. It supports where clauses, joins, ordering, grouping, and aggregate functions like count() and sum(). It's often used for complex queries that don't map cleanly to Eloquent models.

How to study this topic

  1. 1. Read the explanation once end to end, skipping the code.
  2. 2. Re-read the code snippets and say out loud what each line does.
  3. 3. Answer the quiz without scrolling back — that is the real check.
  4. 4. Read every explanation, even for the answers you got right.
