Is there an exclusive OR operator in T-SQL?

Question

This is my statement

IF (@UserName IS NULL AND @EditorKey IS NULL) OR (@UserName IS NOT NULL AND @EditorKey IS NOT NULL) BEGIN
    RAISERROR (\'One of @UserName,         


        

Answer 1

As a cheat, you can do:

If @UserName+@EditorKey is null and coalesce(@UserName,@EditorKey) is not null

It's shorter, but that may be the only thing it has going for it.
