SQL: how to farm journal: select only oldest and newest record for each cust #


 
Is it possible (and simple) to select only two records from the journal - for each file-RRN combination?


Example:

Users make 20 changes throughout the day to CUST #123 record.

I want to select only the first "before" image and the last "after" image for that particular cust (and all other custs).

Can SQL select these with a simple statement?

Or is this best done in an HLL pgm?


Thanks
