Problem with user defined function

Question

CREATE FUNCTION testing(id INT, dsc TEXT) RETURNS TEXT
BEGIN
DECLARE ntxt TEXT;
SET ntxt = dsc;
RETURNS ntxt;
END;

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TEXT' at line 3

What i miss here ?

You forgot to change the delimiter
RETURN has an extra S

This does work:

DELIMITER //

CREATE FUNCTION testing(id INT, dsc TEXT) RETURNS TEXT
BEGIN
    DECLARE ntxt TEXT;
    SET ntxt = dsc;
    RETURN ntxt;
END//

DELIMITER was the problem. Thanks

You probably forgot to add DELIMITER $$ in the very beginning of your script (Standard delimiter is ;, and it's also used in procedures/functions). For example,

 DELIMITER $$
 [CREATE FUNCTION ...... ]
 $$
 DELIMITER ;

why are coders obsessed with the $$ when a single non ; will do - like a # ?

@f00, I guess you feel better when the alternative delimiter is not likely to appear anywhere else.

+1. Just for example :) Surely, it can be anything. Personally I prefer //. But it seems $$ to be more "common"
