I won't disagree with you Corion because "perlguy" does in fact do a few things incorrect. The filter() and Do_SQL() subroutines don't seem all too practical and 'clear'. On the other hand, "perlguy" understandably explains how to SELECT, INSERT, DELETE and UPDATE database entries which i believe were the key points of the tutorial. It is one of the few (only one i found) tutorials which give you an entire program to disect with line-by-line explanations of what is going on.
