For three_tier application,on the appliction server, I put
a TADOConnection,a TADODataSet,a TDataSetProvider In the
Transaction Data Module. The TADOConnect connect a
SQLSERVER database by ado for odbc.

in sqlserver database table,i have a datatime field,
it's default value is (getdate()).

in client app,i insert a new record ,i don't set the
datatime field's value,i want the default value.The
ClientDataSet execute ApplyUpdates(0) successfully.
then i modify one of the records ,error "user by another
user" display.
that is, inserting a new record is right,modifiing a
record is error,why???

thanks

(i am sorry that my english is poor)
