Installing DBI and Using My. SQL with Perl in Linux. You will also see in this tutorial the basics of using DBI to perform queries, and display the results. Once you learn the basics you can use Perl to program the other SQL commands we saw briefly in our class on My. SQL, and you should have learned in more details in the DB course. Please note that we have on reserve at the Library the book Programming the Perl DBI, the authoritative reference to DBI. If you were installing support for another database like Oracle, Informix, etc, you would also have to download their DBD modules. Summary: in this tutorial, you are going to learn how to use Perl DBI (Database Independent) We are going to use CPAN shell to install DBD.

If you did not compile programs in Linux before, don't get scared. They come with programs which run in your machine (the Makefile script), see what you have in terms of software and hardware and create a set of instructions (an executable script/program) which takes care of the compilation. Makefile - - the script to prepare the compilation instructions. At the time this writing the latest version was DBI- 1. You can also read the readme file for it. PERL Simply Easy Learning by tutorialspoint.com tutorialspoint.com i ABOUT THE TUTORIAL Perl Tutorial Perl is a programming language. Installing DBI and Using MySQL with Perl in Linux You will learn in this tutorial how to install the DBI (the Perl interface to databases) in RedHat Linux 7.0 and above.

SQL, Oracle, Informix, etc. These instructions refer to downloading and installing the DBD module for My. SQL, but you can install more than one of the modules to access different types of database software. The same Perl commands wich work for one database type will work for the other types: the code is portable not only across platforms, but also across database software.

This is a modification of the example 1, where we select some fields and we split the query results into variables before printing. Charles St, Baltimore, MD 2. Name: John Morris, Address: 1. N. Charles St, Baltimore, MD 2. Name: Milt Jenkins, Address: 1. N. Charles St, Baltimore, MD 2. Example 3: another way to query and obtain results. Charles St, Baltimore, MD 2. Userid is 4. 58, the name is John Morris, and the address is 1. N. Charles St, Baltimore, MD 2. Userid is 5. 69, the name is Milt Jenkins, and the address is 1. N. Charles St, Baltimore, MD 2.
