LAG Function

918317Mar 26 2012 — edited Mar 27 2012

I have tried looking this up online and through the forum but can not find an answer. If I have one table and need to know the previous value in 3-4 columns, can I use the lag function more than once for all the columns I need? Thanks in advance!
