Nahraďte FLOAT(2)
pouze pomocí FLOAT
:
CREATE OR REPLACE TYPE EmployeeType AS OBJECT (
EmployeeNumber NUMBER,
EmployeeName VARCHAR2(150),
EmployeeAddress VARCHAR2(255),
MAP MEMBER FUNCTION getEmployeeNumber RETURN NUMBER,
MEMBER FUNCTION CalculateSalary RETURN FLOAT
)
NOT FINAL;
/
CREATE OR REPLACE TYPE BODY EmployeeType AS
MAP MEMBER FUNCTION getEmployeeNumber RETURN NUMBER IS
BEGIN
RETURN EmployeeNumber;
END;
-- function that can be overriden by subtypes, make abstract
MEMBER FUNCTION CalculateSalary RETURN FLOAT IS
BEGIN
-- function returns empty, has to be overwritten by fulltimeemployee
RETURN 0.00;
END;
END;
/
