lag lag lag

I picked up lag from this group a few weeks ago and ... nice stuff.
Now I'm trying to create a query that contains a future date. That means all the values in a row are LAG values except for the future date. I can lag a field. How can I lag all the fields? Do you have to write lag(), lag(), lag()... or is there a way to lag once for mutiple fields?
Thank you. Received on Tue Jan 26 2010 - 14:20:26 CST
