Get only Max of each distinct?

[sunilkes@gmail.com]

Hello,

I have a table

ItemID Version

12 1.0
12 1.1
12 2.0
13 2.0
13 1.0
14 1.0
15 1.0
15 5.0
15 2.1

How do I write a Select query to get me all distinct item IDs, whichm
are of the latest version?

Like this:

ItemID Version
12 2.0
13 2.0
14 1.0
15 2.1

Any help would be appreciated.

Thanks

I assume 5.0 is a typo for 2.0

This smells like homework. Look up MAX() and GROUP BY.

Got it, actually it was pretty simple, was trying it incorrectly
earlier !

SELECT MAX(Version_Num ber) AS Maxim, ItemId
FROM tblItems
GROUP BY ItemId
