Multiple FIRST/LAST Queries

[dr4ke]

I currently have a database, which is split into 1 table and numerous queries (below)...

Server1Aggregate1
Server1Aggregate2
Server1Aggregate3
Server1Aggregate4
etc
etc
All the way to Server4Aggregate4

Currently what I have to do is create 3 queries per Server/Aggregate combination to;

Query 1: Displays the Server/Aggregate combination data from Table1
Query 2: Take the FIRST row of data from that specific combination, from Query1, and minus's it from the LAST row of data (giving a difference)
Query 3: Divides the figures from Query 2 to give a 'Daily Growth' and a 'Time Left' figure.



At the end I then use a UNION query to clump all of the Server/Aggregate combination data into one query, which I will then put into a Report.

Is there a way of remodelling the queries I have, and having one to do the First/Last calculations perhaps something like;

IIF(FIND(Server1Aggregate1 do FIRST/LAST sum) THEN (IIF(FIND(Server1Aggregate2 do FIRST/LAST Sum) so on and so on...

is this possible?

I'm ok in Access, but have very very limited knowledge in VBA etc.

How about telling us in 2 or 3 lines what the application is about? What are you trying to do?
Sounds like 1 table is not really representative of what you have, but then that's just a guess.

It's about finding out how long the specified Server has until the memory runs out. All Queries are needed, as they are used to compare the data from the start date and end date. There has to be a 3rd query as I can't mix aggregate and non-aggregate functions together.
