You previously had this sample data:

VoterID AnswerText AnswerID
5 Comments here 2058
5 <NULL> 2057
5 <NULL> 2059

Then you said:

AnswerID is found in the Answer table which corresponds (in this case)
to 2057="Technology" and 2059="Satisfied"

And you want this output:

VoterID Department Rating
---------- ----------------- ------------
5 Technology Satisfied

Somehow we need to magicaly know that answer id 2057 is a department and
that 2059 is a rating. But how do we know that?

There is a general recommedation for this type of questions, and that
is you post:

o CREATE TABLE statements for your table(s).
o INSERT statements with sample data.
o The desired output given the sample.

That makes it possible to copy and paste to develop a tested solution.
Without that, what you get is more or less guessworks. Since you have
already refuted one guess, I don't really feel like playing the game.
I'm sorry, if I'm long-winded, but the bottom line is that to get accurate
help in these forums you must be able to explain your problem so that
others can understand it.
