I was actually preparing myself to ask a very similar question, although mine is geared in a different direction. The only way I can think to do this is to suck all though lines into you're array, then over the entire database (if you have more then one line of data, this). I was also hoping there was another way, becuase I have a plain-text database that comma-separated.
I tried the search yielding meager results that were good, but not actually answering my question. Does anyone else have any ideas?
