I have a table logging application activity.
Each row contains a DateTime ("Time") and an "EventType" column... (And obviously some others that are unimportant here)
I would like to be able to get a count of the number of different EventTypes that occur every hour.
I'm currently getting a basic count of a single EventType with:
select DATEADD(hh, (DATEDIFF(hh,0,Time)),0) as 'hour', count(*) as 'apploads'
from PlaySessionEvent
where EventType = 0
Group By DATEADD(hh,(DATEDIFF(hh,0,Time)),0)
order by hour
What is the easiest way to extend this to count multiple different EventTypes within the same hour?
::Update
Should have specified, I havn't just grouped by the EventType aswell because I only want a subset of all the EventTypes available. (ie. not boring trace/debug data)
Also, I wanted the different event types as columns, rather than additional rows duplicating the DateTime entries.
Eg...
DateTime EventType1 EventType2
12:12:12 12/12/12 45 22
Apologies for the inexact initial question!
