Hi,
 
I get the following error after upgrading a 7.x forum using the access upgrade utility. Everything seem to work completely fine locally. But after upgrading my live site I realise I didnt test posting a message... doh.
 
I guess from other posts something may have gone wrong with the DB upgrade.
 
Help! Error below.
 
Darryl

I've figured out my problem. The access database I was using originally had become corrupted. I managed to export the data out using SQL server 2005 integration services into a fresh copy. This lost the primary key information and autonumbering.
 
Access doesnt want to put an autonumber back on existing data. I also cant re-import the data into an autonumber field.
 
Anyone got any ideas of a way around this?
 
Cheers
Darryl

Can you not just set the field in SQL as an identity field? You should be able to, either with Enterprise Manager if you have access to it, or via some T-SQL script.
