I want to insert multiple records or update those records if 2 specific column values do not exist in a record. But the 2 values are NOT UNIQUE, so I can not use ON DUPLICATE KEY. I am trying to not use IF...Then statements. It seems to be bad programming practice.
Here is the pseudo code of what I want to accomplish.
INSERT INTO interest_list (user_id, interest_id, details)
VALUES
(1, 1,'somestring1'),
(1, 2, 'somestring2'),
...etc
IF the record exists where (user_id==1 and interest_id==1) or (user_id==1 and interest_id==2) ... etc THEN (dont insert but rather update)
UPDATE interest_list
SET details = CASE interest_id
WHEN 1 THEN 'somestring1'
WHEN 2 THEN 'somestring2'
...etc
END
WHERE interest_id IN (1,2...etc) AND user_id=1;
Its fairly complicated to explain, hopefully someone gets my question. I am trying to accomplish this in 1 query.
