So I'm trying to finish my final for my database class except I can't seem to accomplish what I want to do.

Here's the skinny:

I have 10,000 entries of data in one column, each entry consisting of a number 0-5, and in the next column over I want to indicate which of the entries in the column on the left are a "2" or a "3" (so, no, I can't just go through the whole fucking list typing in stuff to indicate which ones are 2's or 3's) so that I can proceed to filter out only the entries of 2's and 3's.

So how do I do this shit?
