Now we have disconnected systems. Now you want 1 computer to rule them all? Lets make a move and make millions off it? Why not have a column with an update trigger for a timestamp. You pass to a sproc the parameters for your update and iit checks if the timestamp is still valid. If so it updates and if not it replies back that it failed to update because of new data in place. Those of you you use an int key just return a negative of the key back. -- Stephen Russell Sr. Analyst Ring Container Technology Oakland TN 901.246-0159 cell --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html --- _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/CAJidMYJgfc=2nyrd7nrgdujwddsa6pzqjmhjxieufb4yb2n...@mail.gmail.com ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
