It cannot be done easily. You can fill in the gaps when you enter new records though. You could also make some new tables with Make Table querries and shift the primary key to a serial numbered field.

from what I understand supposedly it will start at the lowest possible number for you when you repair/compact, but I haven't seen that myself (have tried, but didn't pay a whole lot of attention to it)

you could change the attributes of the autonumber, from incremental to random (which also doubles the possible ranges because it will now include negatives).

Or you can setup your own type of autonuber procedure provided you only use the data tables via a form, and not directly accessing / adding records via table or query

The primary key does not have to be autonumber. If it is, the best way is to use a make table querry and get the records renumbered.

Hi,
I am experiencing the same type of problem.
What I understand is you have to reindex the table.
When I add a record to the table it goes in fine..
When I retrieve that same record base on the different criteria I can see that record. When I retrieve the same record base upon the Primary Key it does not show up and gives me my custom message that value not found in the table.
So I assume you have to reindex it in either case.. But how do you do that?
