Hi, when I work with SQL I find the "Lead\ Lag" function very crutial.
I'm using it mostly between dates.
Does splunk supply an alternative?
thanks!

You could use streamstats (http://docs.splunk.com/Documentation/Splunk/4.3/SearchReference/Streamstats ). Say you want LAG(field):

... | streamstats current=f last(field) as last_field

For LEAD, just get the results in reverse order (using reverse).

You might also want to have a look at delta which computes differences between values of a field for different events. http://docs.splunk.com/Documentation/Splunk/4.3/SearchReference/Delta

What if I want to lag values 7 rows apart (not just the previous one)?
