Hi Perry,
Does UV support SAMPLED? If so, use:
SELECT file SAMPLE 3000000 SAMPLED nnnn
where nnnn is the number of records to skip between sample IDs picked
up. If it doesn't, you're probably going to have to write a little program.
Regards,
Charlie

I have several *very* large files on which I need to perform some file sizing
diagnostics. Rather than repeatedly running HASH.AID against these files is
there a good way to sample say 2-3 million records to copy into a test file?
SAMPLE will only grab the first n records in hash order and I'm thinking that
would not necessarily be a good representative sample of the file's contents.
Am I up in the night thinking this is the case? Is there a better way to get a
good sample of records for this purpose?
Thanks.
