mysql/mariadb - syntax error: creating database function

Question

im having trouble finding the correct syntax i always having error #1064.

error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ';

this is the code;

DELIMITER $$

DROP FUNCTION IF EXISTS formula $$

CREATE FUNCTION formula (iq INT, sq INT, ig INT) RETURNS INT

BEGIN

DECLARE result INT;

SET result = (iq-((sq/30)) * ig;

IF result >= 0 THEN
    RETURN result;
ELSEIF result < 0  THEN
    RETURN 0;
END IF;

END; $$

DELIMITER;

i've searching for the answer in the web nothing i can find. what is the wrong with my syntax?

Answer 1

you have a very small mistake in the code.

DELIMITER $$

DROP FUNCTION IF EXISTS formula$$

CREATE FUNCTION formula(iq INT, sq INT, ig INT) RETURNS INT

BEGIN

DECLARE result INT;

SET result = (iq-((sq/30))) * ig; ---> You missed an closing bracket (")") here

IF result >= 0 THEN RETURN result; ELSEIF result < 0 THEN RETURN 0; END IF; END; $$

DELIMITER;
