Consider this an add-on to my previous meditation "A corrolary to TMTOWTDI".

I'm digging into PL/SQL and I'm reading Oracle PL/SQL Programming by Steven Feuerstein. On page 31 of this 1,000-page monster, there's a section entitled "Assume that PL/SQL has what you need."

Programmers who are new to PL/SQL often make the mistake of starting their coding efforts before they are sufficiently familiar with everything the language has to offer. I have seen and heard of many instances where a developer spends valuable time writing procedures or functions that duplicate built-in functionality provided by PL/SQL.

Please don't write a function that looks through each character in a string until it finds a match and then returns the index of that match in the string. The INSTR function does this for you. Please don't write a function to convert your string from uppercase to lowercase by performing ASCII code-table shifting. Use the LOWER function instead.

Maybe that's the essence of it all. Maybe the key idea is for newbies to "assume that Perl has what you need."
