RE: Arrays

[MWalter@xxxxxxxxxxxxxxx]

SQL definitely is made for stuff like this. It's made to work with sets of
data. One record at a time, use tradition I/O. Want to grab a bunch of
records at once, use SQL. Boy, I hope I didn't start another holy war.

Thanks,

Mark

Printed and archived for future use......Thanks Rob.  I'll give it a shot,
depending how large the files are, my "old school" method of using work
