Maybe purer, but not very efficient (or real-world). Or he could have used Fox tables with moving the record pointer and spin even more. :-)


Of course there are sometimes valid reasons to stray from relational rules for performance reasons. This one just seems especially crude. The unaware may think this is the first way to do things.

Not sure what you mean by sucking down the entire table every time. Why would you want to do that? Read it once and then loop through the data in an interface with the GUI layer.
