Purpose

Evaluates a set of expressions for equality with a test expression and returns as its result the value of the scalar expression defined for the first WHEN clause whose value equals that of the test expression. If no equality is found, then CASE returns the scalar value defined by an optional ELSE clause, or if omitted, NULL.
