  • 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.
