Hello, i'm trying to move one database from FB1 to FB 2.1.3 classic server.

I'm getting errors with message

This column cannot be updated because it is derived from an SQL function or expression. attempted update of read-only column.

This error raises when calling a storedproc, and in the first line of the stored proc i have writed

exception XXXX; to force the exception, and the error still raises.

I have done it from my app and ibmanager executing the stored proc.

The same one is executed fine in FB1, IB 2007, IB 2009.

¿has anyone had this problem?

regards
