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. A PL/Perl function is called in a scalar context, so it can't return a list.
Here's the source code I created to perform this Perl array search and replace operation (a Perl replace regex operation): This Perl program does the following: 1  Open a file, where the file is given by the variable $fileName.2  Read the contents of the file into the Perl array variable named @fileContents. 3  Closes the file. Open a file, where the file is given by the variable $fileName. 2  Read the contents of the file into the Perl array variable named @fileContents. 3  Closes the file. 4  Loops through each element in the @fileContents array, and does the desired Perl search and replace operations (using the regular expressions shown).
