CREATE OR REPLACE FUNCTION isLeapYear(i_year NUMBER) RETURN boolean AS
BEGIN
IF mod(i_year, 400) = 0 OR ( mod(i_year, 4) = 0 AND mod(i_year, 100) != 0) THEN
return TRUE;
ELSE
return FALSE;
END IF;
END;
---------------------------- Calling the function in a PL/SQL program -----------------------------------
BEGIN
IF isLeapYear(&year) THEN
dbms_output.put_line('Yes, it is a leap year');
ELSE
dbms_output.put_line('No, it is not a leap year');
END IF;
END;
