Perl DBI Programming Reading notes, in the original text see:http://www.ibm.com/developerworks/cn/linux/l-cn-perldbi/In order to communicate with the database, the Perl community developed a unified Database communication interface module: DBI. DBI,

The most commonly used package for Perl access to a database is DBI, which can be found in www.cpan.org. Also need to install the corresponding database driver package, such as Dbd::mysql, Dbd::oracle, dbd::sybase or DBD::ODBC.First, the basic

A Perl application database uses the DBM package configured by itself to create and operate a database, therefore, the DBM package and other similar packages can be considered as a database extension. The other is to use the DBI package or similar

Using DBI, Perl makes it easy to connect to the MySQL database: The code is as follows: Copy Code code as follows: #!/bin/perl Use DBI; # Connect to Target DBMy $dbh = Dbi->connect ("Dbi:mysql:database=eygle;host=localhost",

Using DBI to connect to a Microsoft SQL server is a relatively simple task. Rather than go with a simple example, I have chosen to demonstrate not just connectivity, but also error checking.As always, when you want to use a module, you must declare

web| programs So far, we have written dbi scripts for command interpreters in a command-line environment, but DBI is useful in other environments, such as in the development of web-based applications. When you write a DBI script that can be invoked

One of the most important modules in Perl is the DBI module (Perl database Interface, DB interface). The DBI module provides a unified interface for many different databases. This interface makes it easy for Perl to manipulate the database. The
