Dear List,
I want to create a stored procedure that runs a query using the "IN"
operator (or is "IN" a function???) on values sent as argument. That is,
my procedure should be called with something like:
CALL get_users((1,2));
and I was hoping to implement something like this:
CREATE PROCEDURE get_users(uids "LIST") -- what type to use here?
BEGIN
SELECT * FROM user_test WHERE user_id IN uids;
END::
Thanks,
Magne Westlie
Working test code for getting one user only:
----------------------------------------------
DROP TABLE IF EXISTS user_test;
CREATE TABLE user_test (
user_id INT,
user_name VARCHAR(100),
PRIMARY KEY (user_id)
) ENGINE=MyIsam;
INSERT INTO user_test VALUES(1, 'Bob');
INSERT INTO user_test VALUES(2, 'Ann');
INSERT INTO user_test VALUES(3, 'Bill');
DROP PROCEDURE IF EXISTS get_users;
DELIMITER ::
CREATE PROCEDURE get_users(uid INT)
BEGIN
SELECT * FROM user_test WHERE user_id = uid;
END::
DELIMITER ;
CALL get_users(3);
