Description: SQL Correlated Subqueries are a powerful yet often underutilized feature of SQL. They can help you get more out of the data you have, but they're also difficult to understand and apply correctly. This Ultimate SQL Correlated Subquery Guide is a comprehensive reference to correlated subqueries, a powerful technique for optimizing queries.

Question

Accepted Answer

A SQL correlated subquery executes a query once for each record returned by the outer query. It's called correlated because there's a link between how many times the subquery is run and how many records the outer query returns (not the subquery).
