MySQL has two conditional control statements: IF and CASE, which have similar functions. The IF statement verifies a condition and executes a set of SQL statements based on the condition. The CASE expression performs if-then-else logic in SQL and can be used in various contexts like SELECT, WHERE, and ORDER BY clauses. The IF statement has three types: IF-THEN and IF-THEN-ELSEIF-ELSE. The IF statement returns one of the three values True, False, or NULL. The CASE expression checks all conditions and returns a value if the first condition is met. The syntax for the IF statement is: IF... Show more MySQL has two conditional control statements: IF and CASE, which have similar functions.
