I have a problem while trying to update my database. I receive the above errormessage.

This is my situation:

ServerApp with OracleDataset with a TDatasetprovider linked to it. The UpdateMode of this provider is set to upWhereKeyOnly.

ClientApp using a TSocketConnection to attach to the server. A TClientdataset is linked to TDatasetprovider of the server. There's a persistent fieldobject 'ID' of which Providerflags pfInkey set.

Any time I try to update the database I receive the above errormessage.

Anyone has a solution to this problem?
