Που κάνω λάθος (phpmyadmin)

[Uberalles_gr]

Έχω τον παρακάτω κώδικα

>
CREATE DEFINER = 'root'@'%' FUNCTION `strip_tags`(
       x longtext
   )
   RETURNS longtext CHARSET utf8
   NOT DETERMINISTIC
   READS SQL DATA
   SQL SECURITY DEFINER
   COMMENT ''
BEGIN
DECLARE sstart INT UNSIGNED;
DECLARE ends INT UNSIGNED;
SET sstart = LOCATE('<', x, 1);
REPEAT
SET ends = LOCATE('>', x, sstart);
SET x = CONCAT(SUBSTRING( x, 1 ,sstart -1) ,SUBSTRING(x, ends +1 )) ;
SET sstart = LOCATE('<', x, 1);
UNTIL sstart < 1 END REPEAT;
return x;
END;

 

και το τρέχω σε sql editor στο phpmyadmin και μου βγάζει το παρακάτω error

>
Η MySQL επέστρεψε το μήνυμα: Τεκμηρίωση
#1064 - 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 '' at line 10
