No Changes?

Hello All!
Im reading a book on SQL Server, and it says it is possible to set a column
with 'No Changes' property.
I have searched google and i cant seen to find where to set it, can u guys
help me out here?
Thanks,
Bruno NThere's no such property in SQL Server. Perhaps you misinterpreted the text,
or perhaps the authors
is mistaken. You can accomplish the same effect using a trigger, however.
