Understanding Scalar Subqueries in SQL: Simplifying Complex Queries with Aggregate Values
Understanding Scalar Subqueries in SQL Introduction to Subqueries In SQL, a subquery is a query nested inside another query. This inner query can return one or more values that are used by the outer query. There are two types of subqueries: inline views and scalar subqueries. Inline views return a result set that can be used like any other table in the outer query. Scalar subqueries, on the other hand, return a single value that is then used in the outer query.
