Hi Emanuele.

I can't reproduce this. When I created a CursorAdapter similar to yours, the BeforeUpdate method showed that the update command sent to SQL Server was:

UPDATE CUSTOMERS SET COMPANYNAME=?customer.companyname WHERE CUSTOMERID=?OLDVAL('customerid','customer') AND COMPANYNAME=?OLDVAL('companyname','customer')

In SQL Profiler, the command received was:

exec sp_executesql N'UPDATE CUSTOMERS SET COMPANYNAME=@P1  WHERE CUSTOMERID=@P2  AND COMPANYNAME=@P3 ', N'@P1 varchar(40),@P2 varchar(5),@P3 varchar(40)', 'Alfreds Futterkistee                    ', 'ALFKI', 'Alfreds Futterkiste                     '
