Perl DBI API Reference
H Perl DBI API Reference This appendix describes the Perl DBI application programming interface. The API consists of a set of methods and attributes for communicating with database servers and accessing databases from Perl scripts. The appendix also describes MySQL-specific extensions to DBI provided by DBD::mysql, the MySQL database driver. I assume here a minimum version of DBI 1.50, although most of the material applies to earlier versions as well. DBI 1.50 requires at least Perl 5.6.0 (with 5.6.1 preferred). As of DBI 1.611, the minimum Perl version is 5.8.1. I also assume a minimum version of DBD::mysql 4.00. To determine your versions of DBI and DBD::mysql (assuming that they are installed), run this program: #!/usr/bin/perl # dbi-version.pl - display DBI and DBD::mysql versions use DBI; print "DBI::VERSION: $DBI::VERSION\n"; use DBD::mysql; print "DBD::mysql::VERSION: $DBD::mysql::VERSION\n"; If you need to install the DBI software, see Appendix A , “Software Required to Use This Book.” Some DBI methods and attributes are not discussed here, either because they do not apply to MySQL or because they are experimental methods that may change as they are developed or may even be dropped. Some MySQL-specific DBD methods are not discussed because they are obsolete. For more information about new or obsolete methods, see the DBI or DBD::mysql documentation, available at http://dbi.perl.org or by running the following commands: % perldoc DBI % perldoc DBI::FAQ % perldoc DBD::mysql The examples in this appendix are only brief code fragments. -

It's also a good language for many system management tasks. The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal). -
Name Description
Perl version 5.10.0 documentation - perlnewmod NAME perlnewmod - preparing a new module for distribution DESCRIPTION This document gives you some suggestions about how to go about writingPerl modules, preparing them for distribution, and making them availablevia CPAN. One of the things that makes Perl really powerful is the fact that Perlhackers tend to want to share the solutions to problems they've faced,so you and I don't have to battle with the same problem again. The main way they do this is by abstracting the solution into a Perlmodule. If you don't know what one of these is, the rest of thisdocument isn't going to be much use to you. You're also missing out onan awful lot of useful code; consider having a look at perlmod, perlmodlib and perlmodinstall before coming back here. When you've found that there isn't a module available for what you'retrying to do, and you've had to write the code yourself, considerpackaging up the solution into a module and uploading it to CPAN so thatothers can benefit. Warning We're going to primarily concentrate on Perl-only modules here, ratherthan XS modules. XS modules serve a rather different purpose, andyou should consider different things before distributing them - thepopularity of the library you are gluing, the portability to otheroperating systems, and so on. However, the notes on preparing the Perlside of the module and packaging and distributing it will apply equallywell to an XS module as a pure-Perl one. What should I make into a module? You should make a module out of any code that you think is going to beuseful to others.
