mysql function error

#1 (**permalink**) 02-28-2008, 10:29 AM

dear all,

I have a table called "distributor" having "distributor_id" as a PK
and taking an integer data type as well as "distributor_parent_id"
which also takes an integer data type but can accept null values;

I tried to make this simple function that returns the parent_id by
taking a parameter representing the distributor id; still it fails, I
assume due to the delimiters.

I appreciate any assistance to this regard.

DELIMITER $$

CREATE FUNCTION last_inserted_parent_id ( inserted_id INT )
RETURNS INT
BEGIN
DECLARE parent_id INT$$
SET parent_id = (
SELECT distributor_parent_id
FROM distributor
WHERE distributor_id = inserted_id
)
RETURN parent_id$$
END$$
$$

DELIMITER ;

Your assumption is correct.
Read it up in the manual, there is a nice example in the
first hit when you search the MySQL 5.1 Reference manual
for DELIMITER.

I would appreciate if you would assist yourself.
You can express your appreciation for the creators of
MySQL and its manual by using that same manual.
