> ah, but it only LOOKs like a relation. that's the gotcha.

All tables only LOOK like relations. But some look more like relations than others.

In particular, eliminating duplicate rows is a big step towards making the result table LOOK like a relation.

Everything inside a computer only looks like what it represents. There aren't really any numbers inside a computer. Only signals and states that represent digits. There aren't really any characters inside a computer. Only codes that represent characters. How much of cyberspace is about representation? All of it. Received on Tue Apr 27 2004 - 07:46:05 CDT
