- Hi,
- Could someone please give me some hints on how to do the following?
- I have a library database to keep track of my books. One of the fields
- is a category field (science fiction, non fiction, biography, etc.). One
- field is an auto-serial number (unique), and yet a third field is a calcula-
- tion field that contains something like: Upper(Left(category,3)) &"."& num
- (where num is the autoserial field); this results in stuff like:
- SCI.588 or BIO.212 etc.
-
- My problem is, that I would like any books in a specific category to
- go sequentially, i.e., SCI.400, SCI.401, SCI.401, etc. As I have it
- set up, if I enter a SCI book, then a Biography, then a SCI book, I'd get:
- SCI.400, SCI.402 (since the biography would get BIO.401). I can't set
- up separate "autoserial" number fields for each category, since they
- would ALL increment by 1 as soon as I create a NEW record. Is there a
- way for me to do what I'd like?
-
- Thanks much in advance,
- -John Boswell
