Charles,

He wants to set ClientVersion to 1 + Max(Clientversion) when ClientVersion = 0 and the ClientID is in the transaction table. Odd but that's what he wants. Your Update bumps up the client version in all the records.

Assuming ClientID is unique in both tables....

update ClientTable
set ClientVersion = ClientVersion + 1
where clientID in (select clientID from NewClientTable);

insert into ClientTable (ClientID, ClientName, ClientVersion)
(select ClientID, ClientName, 0
from NewClientTable);

HTH,
Charles

Here's my client file that I want to update :

ClientId  ÂClientName ÂClientVersion
15       ÂBigs          Â0


I receive a file containing clientId and the new name of the client, eg, clientId 15 becomes 'Smith'. But I can't just update the client file from this work file. I need to archive the original name, so I have this kind of representation after the update :

ClientId  ÂClientName ÂClientVersion
15       ÂSmith          0
15       ÂBigs          Â1

There's a timestamp field among the other fields. Version 0 is always updated to n+1 and a new line is written to the file. So, in the example, I've updated the line Bigs and I've written the line Smith.

So, version 0 is the current version and 1 is the old one. If I change now to 'Eggs', I want to see :

ClientId  ÂClientName ÂClientVersion
15       ÂEggs          Â0
15       ÂBigs          Â1
15       ÂSmith          2



I ask because I get this request now and again, for a few thousand clients at a time. I'm having to use an RPG to write to the client file, but I always end up using SQL to prepare a work file for that RPG.

Thanks.
