RE: Deleting with SQL

Although that second line sounds wrong, I think that is a correct
interpretation of the end results.

So for every program, you'll end up with...
either
- >= 30 entries, starting at 2/15/2015
- <= 30 entries, going back as far as needed? (assuming it's possible that
you don't have 30 entries currently logged)

I have a file that is a log of who ran programs on what date that I

on keeping x number of entries and entries before x date. For
example, I need to keep all entries after 02/15/2015 AND also the last
30 entries. So, if an entry falls inside of either of these criteria,
I keep it. The user is immaterial to the result set.



I'm not sure I have explained that very well but in the event that I
have, can anyone tell me how to do it through SQL?
