From: Bre-x on 5 May 2010 12:39 How do I create my autoincrement number? My Table main_index (AutoNumber), payee_id (Number), main_amount (Currency), main_receipt (Number) if my Last Receipt Number was 500, I would like to update my main_receipt with the next number 501, 502, 503, etc, etc, according th main_idex field. Thank you all, Bre-x
From: Jeff Boyce on 5 May 2010 12:47 If you are using Access' Autonumber data type, be aware that it is ONLY designed to provide a unique identifier. It is not guaranteed to be sequential, and is generally unfit for human consumption. If you MUST have a sequential number (i.e., a "sequence number"), you'll need to 'roll your own' code to generate it. Check online for "custom autonumber" for variations on how to do this. Note, you can keep your Autonumber primary key, but you'll need to add a numeric-type field to hold your (new) sequence number.

From: Bre-x on 5 May 2010 15:02 I coundn't find what I am looking for, most of the instructions are to reset the autonumber. I am looking for a way to auto increment a field. After a few hundred records have been inserted I need to find a way to auto increase the main_receipt starting from a number in another table. Help!!!!!!

If (as you should!) you are doing your data entry through a Form, you can put code in the form's BeforeInsert event: Private Sub Form_BeforeInsert(Cancel as Integer) Me!main_receipt = NZ(DMax("[main_receipt]", "[yourtablename]")) + 1 End Sub You may want to consider that main_index and main_receipt are now functionally equivalent (both are Long Integer unique identifiers for the record); you could consider making main_receipt the Primary Key and removing the autonumber field altogether. This will require some snarky update queries if you have related tables, however. -- John W. Vinson [MVP]
From: KenSheridan via AccessMonster.com on 6 May 2010 16:57 Roger Carlson has simple solutions for both single and multi-user environments at: http://www.rogersaccesslibrary.com/forum/topic395.html while my slightly more complex solution at: http://community.netscape.com/n/pfx/forum.aspx?nav=libraryMessages&tsn=1&tid=23839&webtag=ws-msdevapps also allows the number to be 're-seeded' with a number at which the sequence will re-start when the next record is added. This could be adapted to re- start the sequence with your number from another table.
