Try this:

Expand|Select|Wrap|Line Numbers
  1. Update Engineer Set Id = @mechId, StatusId = 1,
  2. studentname = isnull(@studentname, studentname)
  3. Where RID = @RID 

In case @studentname = null it will replace with the name in a studentname column back to what ever it was so name will be preserved.

Good Luck.
