Hi

I have a "password" field in a Table. How should I define it, that its output is showed like "******"?

Hi

You can encrypt the contents of the column using several different methods
see http://www.sqlsecurity.com/DesktopDefault.aspx?tabid=30

If you are using .NET then the best thing to use is one off the algorithms
available through the framework.

The displaying of asterisks in a form is a feature of the form and not part
of SQL Server.
