One of our customers has an Invoice Header file that currently has
815,000 records and is growing daily and I need to try and identify any
blocks of missing numbers. I could do this quite easily with a simple
RPG (or even CL!) program, but would have to go through the full change
management rules to get it approved, tested, system tested, user tested,
deployed, etc, and there isn't the time.
Is it possible using SQL to generate a list of invoice numbers where the
next invoice number doesn't exist. For example, if invoice numbers 1,
2, 3, 6, 7, 11, 12 and 15 existed the list would show 3, 7, 12 and 15
(although I'm not too worried about the last one).
I'm doubting there is, but figured I would ask.
Thanks
Jonathan
