Yes. And your query is a sub query <em>after</em> I know all the distinct
items in the table. I was thinking something like:
SELECT ItemID, ItemName, Version FROM [table] WHERE Version = (SELECT
MAX(Version))
...but that didn't work.

Are these fields from a database?
If so what about?: SELECT MAX(Version) from [table] WHERE Item Name =
['ABC'], etc.
Hi Listeroo's:
I'm looking at different strategies for getting the last version of a
collection of objects and am seeking your advice. Take:
Item ID Item Name Version
1 ABC 1
2 ABC 2
3 ABC 3
4 DEF 1
5 GHI 1
6 GHI 2
7 ABC 4
8 DEF 2
9 DEF 3
What I want as a returned record set is
ItemID Item Name Version
7 ABC 4
9 DEF 3
6 GHI 2
The straight forward approach would be to get a list of distinct projects:
ABC, DEF, GHI. The traverse all items by each name and get the last version
of each one. My initial thoughts lead me to a multidimensional array, but
there HAS to be an easier way to do this. (After a long day of coding, I
tend not to think straight anymore.)
Is there some kind of query that'll do this for me in one move?
