First of all, we need a little more information as to what it is you are really trying to accomplish. For example, I can tell you that the answer is YES to your question. However, depending on what you are doing and how you are doing it may determine which way we specify how you should do it, or it could reveal that you are not doing things in a properly normalized way and we should fix that.
So, more information, please - what is it you are really trying to accomplish.
