Hi folks,

In SQL Server 2008, how do i update fields in a table only if their values differ with the values in the update statement ?

For ex:

I have TableA with column FirstName whose value is 'Roger Moore' with an unique id of '007'. Now, i am calling an update statement but it should update the 'FirstName' field only if value is something else other than 'Roger Moore'.

TIA
