A quick thought - use a UNION SELECT. This assumes you have some
criteria for the particular set of records - the first SELECT would get
the record with some minimum timestamp, the second SELECT would get the
record with some maximum timestamp.
I'm just flying off the cuff with this - not sure it'd work at all -
depends on how the data comes out. It'll work in a general sense, though.

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?
