To create a function in the PL/Perl language, use the standard CREATE FUNCTION syntax: The body of the function is ordinary Perl code. In fact, the PL/Perl glue code wraps it inside a Perl subroutine.
To use pattern matching in Perl, you figure out what you want to find, you write a regular expression to find it, and then you stick that pattern in a situation where the result of finding (or not finding) that pattern makes sense.hereas other languages may provide regular expression libraries or functions, pattern matching is intrinsic to Perl's operation and tightly bound to many other aspects of the language. Perl without regular expressions is just another funny-looking language.
