    how to insert null to an EMPTY cell in SQL SERVER...

    i.e, in a field, i enter some values and deleted it. so, it is considered as EMPTY field and not null. i need a query to make that field <NULL>

    can anyone help me?

    Hi Karan,

    From my experience you can insert the null value to sql server by using "DbNull.Value" or "null". So far it worked for me..
