Re: Finding gaps in a sequence of invoice numbers using SQL

So how come software written in SQL is exempted from change management at the company? Are other languages like COBOL also exempted?

Do the rules specify a particular version of RPG, for example ... if they say that any programs written in RPG ILE go through change management, then maybe you have access to an earlier version like RPG/400 or RPG 2.5 & saying that the rules don't include all versions of RPG, then you can do the job in a different older version.

Sounds to me like the change management system needs to go through change management to authorize the creation of reports when investigating some crisis, like running out of numbers, or other situation that might interfere with business continuity.

If the invoice # can only go up to 6 digits, then maybe what is needed is a system for archiving oldest, based on date of issuance, and fact of paid ... we have customers with invoices unresolved from 2 years ago, so we need to hang onto the invoice detail to participate in the customer game of infinitely asking again for, and receiving, details on the invoice.

Hi Everyone

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
