Question

I have 2 tables

User
-userid
-group
//other unrelated columns

Logs
-userid
-ip

What I want to do is using an IP query the Logs table for all userids and then get the groups of all the userids. Is this possible with a single query? If not is there anyway to speed it up other than querying every User row with the userid?

Answer 1

Something like this?

SELECT ip, userid, group
FROM Logs INNER JOIN User ON Logs.userid = User.userid
WHERE ip = '1.2.3.4'
