Question

Im coming back to needing to use SQL again after not using it for years, and im running into an issue when trying to do something I guess would be considered a join. Heres what I got. I got a username which I need to reference back to a user_id, which is a simple

SELECT chat_user_id FROM chat_users WHERE chat_username = 'A1A1' 

That works fine, but now I need to pass the chat_user_id to another query to get the chats related to that user_id. I know I have done this before, but havent done it in a long time. Any help would be greatly appreciated.

Answer 1

SELECT whatever
FROM   chats c
INNER JOIN chat_users cu ON c.chat_user_id = cu.chat_user_id
WHERE  ch.chat_username = 'A1A1'
