The RETURN statement terminates the current function, procedure, or anonymous block and returns control to the caller.
The RETURN statement is available in two forms. The first form of the RETURN statement is used to terminate a procedure or function that returns void. Syntax:
RETURN;
The second form of the RETURN statement returns a value to the caller. Syntax:
RETURN expression;
expression must evaluate to the same data type as the return type of the function.
The following example uses the RETURN statement to return a value to the caller:
CREATE OR REPLACE FUNCTION emp_comp (
p_sal NUMBER,
p_comm NUMBER
) RETURN NUMBER
IS
BEGIN
RETURN (p_sal + NVL(p_comm, 0)) * 24;
END emp_comp;
