Question

Well, the first is more expressive of your intent. The last is clearly messy (hard-coded length etc). I doubt you'd find much performance difference between the first & second, so I'd use the simplest - RIGHT.

Of course, if you are doing this lots, you could write a udf that encapsulates this - then if you change your mind you only have one place to change...
