I'm doing an assignment for a class where I should determine if the person's age is between one of the following categories:
AGE CLASSIFICATION
0-14 Children
15-24 Early working age
25-54 Prime working age
55-64 Mature working age
65 and above Elderly
This is what my script currently looks like:
DELIMITER //
CREATE FUNCTION `Employee_age_classification`(`Employees_Last_Name` VARCHAR(50)) RETURNS varchar(50) CHARSET utf8mb4
DETERMINISTIC
BEGIN
DECLARE CLASS VARCHAR(50);
DECLARE AGE INT;
DECLARE LASTN VARCHAR(50);
SELECT TIMESTAMPDIFF(YEAR,Bdate,CURDATE())
INTO AGE
FROM EMPLOYEE
WHERE Lname = Employees_Last_Name;
IF AGE>=0 AND AGE<=14 THEN SET CLASS = 'Children';
ELSEIF AGE>=15 AND AGE<=24 THEN SET CLASS = 'Early Working Age';
ELSEIF AGE>=25 AND AGE<=54 THEN SET CLASS = 'Prime Working Age';
ELSEIF AGE>=55 AND AGE<=64 THEN SET CLASS = 'Mature Working Age';
ELSEIF AGE>=65 THEN SET CLASS = 'Elderly';
END IF;
RETURN CLASS;
DELIMITER;
It shows an error when I try to run it.
Error Code: 1064. You have an error in your SQL syntax.
How can I fix this?

You are missing an END statement before the last DELIMITER -
