Which SQL pattern accurately returns rows in A that have no match in B?

Problem Statement

Explanation

The anti-join pattern uses a left join and then filters for rows where the right side is missing. This expresses “in A but not in B”. The same logic can be written with NOT EXISTS. Choose the form that is clearest and performs well in your engine.
