The CASE statement in SQL is used to perform conditional logic within a query. It allows you to return different values based on specific conditions, making it a powerful tool for handling complex queries and data transformations. The CASE statement can be used in SELECT, UPDATE, and ORDER BY clauses, among others. It operates by evaluating a series of conditions and returning a corresponding result when a condition is met.
