Hello everyone,
I have the following select statement
SELECT DISTINCT sessionID, userID, date, time FROM sti_tracking WHERE userID = 999
What I want is to have only records with the userID of 99 and where the sessionID is distinct (meaning only on of each session id). Neither sessionID nor userID are keys or unique.
Obviously this isn't working.
Can someone suggest how this should be done?
If I understand you properly, you want only a single line for each of userID 999's sessions, is that right? Is there some specific date and time that you are interested in for that session, for instance, the first? If so, try:
SELECT sessionID, userID, min(date), min(time) FROM sti_tracking WHERE userID = 999 GROUP BY userI, sessionID
Even if I misunderstood, you can probably adapt this into what you really want.
