I changed the field to a TIntegerField, turned off the ReadOnly property and set the provider flag to [pfInKey] On the client side I am inserting a new record, populating the identity column with -1, -2, etc as necessary to distinguish the records on the client. WHen I applyupdates, I get an error that I cannot explicitly set and identity column value. I profiled the query and it is indeed, using the identity column in the insert statement, which it should not be doing. I am doing this exact same thing in countless other datasets in our project and I can't seem to find anything different between them. Why is Delphi insisting on including the identity column in the insert statement? How can I force this not to happen? Brandon -- "In the beginning the universe was created.

Ahhh, thanks. For some reason the code I was using as a template had the read-only property of the field set to FALSE, so I assumed it was necessary.

Setting the identity field's ReadOnly property to True did get rid of it in the insert, but the code I use to populate the identity column on the server so that it can propogate back to the client doesn't work because the field is read-only. This explains why the other identity columns in other datasets are not read-only, but still doesn't explain why they work, and this one doesn't.. Help!

Try setting the server column to read-only, and the client column to read-write.

All I did, was turn the column back to not be ReadOnly..... There must have been something messed up in Delphi that was causing a property of the field/dataset/provider not to get set correctly. It works now, however. Cheers, Brandon -- "In the beginning the universe was created.
