If you can correct the TOP(n) queries with ORDER BY, or better still MIN or MAX, it will clarify your intent. That in turn would make it much easier to rewrite this lot. It's well worth it.

Thanks Chris,
But the STN no is generation is based on FromStoreCode not random numbers....

If you can correct the TOP(n) queries with ORDER BY, or better still MIN or MAX, it will clarify your intent. That in turn would make it much easier to rewrite this lot. It's well worth it.

As long as you are using TOP without ORDER BY, you could get any FromStoreCode which is within scope of the WHERE clause. That's what I mean by random.

Use MAX() or MIN(), or use TOP with ORDER BY.
