I have a file that is a log of who ran programs on what date that I
need to purge but the purge has dual criteria. I need to purge based
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?
