I've determined that I don't seem to
be able to create functions at all.
Declare a delimiter, and lose the quote around the function name, eg
DROP FUNCTION IF EXISTS weighted_average;
DELIMITER |
CREATE FUNCTION weighted_average(n1 INT, n2 INT, n3 INT, n4 INT) RETURNS
int(11)
DETERMINISTIC
BEGIN
DECLARE avg INT;
SET avg = (n1+n2+n3*2+n4*4)/8;
RETURN avg;
END;
|
DELIMITER ;

All,
I've been trying to create a function that will generate URLs so that I
wouldn't have to wrote ugly SQL all the time. After no success, I've determined
that I don't seem to be able to create functions at all. I am relatively new to
mysql development (or management), so any advice is appreciated (coming from
oracle world, btw)
