Thank you, I was just preparing to post the create statements and a text file of some data.

I will take a look at your code. With regards to all rows containing the same exact format; not really...

SOME will have no range in it (44100-44110) and only contain things like 44110,44125,44157, etc (maybe three or so values, maybe 20)...

Other fields might have multiple ranges

ex: 441100-44110, 44128, 44524-44555, 44112, 52144

Things like this... Makes it interesting for sure.
