>Please don't take this as a critcism, but you are looking for a class to replace 3-4 lines of code MAX. If you write it yourself as straightforward in-line code you will save memory and it'll probably execute faster too.

This is not true. If you want to build a QBF interface that allows users to select as many or as few filters from x number of fields, then you need a class like this. You can not code it straight in line, because you don't want irrelevant filters in your WHERE clause.

I have had need for a class like this many times, but have never yet taken the time to build a generic one, I have just handled it per situation so far.

I, too will be watching this thread for ideas.
