Topic: DBI


In the News (Sat 11 Oct 08)

  
  Perl DBI - Wikipedia, the free encyclopedia
DBI was specified by Tim Bunce, in collaboration with others, starting in 1994, and is currently maintained across the Internet as a CPAN module in accordance with the Open Source model.
The DBI and DBD Perl packages allow Perl programmers to view the many database environments that are on the market in a uniform way.
The latest DBI module for Perl from CPAN is available for a range of operating systems.

 Free2Code - articles - Perl DBI
The Perl DBI is a perl module that allows Perl users to interact with different types of databases through a single API.
DBI means Database Independent, we can use this to talk to a MySQL database, an Oracle database and many more.
The job of the DBI level is to translate the information sent to it by the Perl script, into a language the database driver we're using can understand.

 DBI - Database independent interface for Perl
It is used internally by the DBI for trace output.
DBI trace information can be enabled for a specific handle (and any future children of that handle) by setting the trace level using the trace method.
To do this the DBI driver will automatically begin a transaction when AutoCommit is turned off (from the default on state) and will automatically begin another transaction after a commit or rollback.

 O'Reilly Network Safari Bookshelf - Programming the Perl DBI
Programming the Perl DBI is coauthored by Alligator Descartes, one of the most active members of the DBI community, and by Tim Bunce, the inventor of DBI.
DBI is a database-independent package that provides a consistent set of routines regardless of what database product you use--Oracle, Sybase, Ingres, Informix, you name it.
The design of DBI is to separate the actual database drivers (DBDs) from the programmer's API, so any DBI program can work with any database, or even with multiple databases by different vendors simultaneously.

 Using the Ruby DBI Module
It is an adjunct to and not a substitute for the DBI specification documents.
DBI substitutes the values into the statement where the placeholders appear, performing any quoting of string values and escaping of special characters as necessary.
The DBI documentation isn't specific on the meaning of these attributes, but they appear to represent the error number, a descriptive error string, and some kind of "standard" error code.

 Databases -- an introduction to the DBI
The DBI is an abstraction layer allowing you to access all types of datastores using a consistent and object-oriented interface.
The DBI is designed to be as thin a layer as possible to ensure database operations aren't slowed by the accessor method.
You can think of the DBI as a pass-through module: it defines an interface for sending requests to and receiving data from a database, but it does not really care what the statements or data are.

 Programming the Perl DBI: Chapter 4: Programming with DBI
All that is required is to implement the methods defined in the DBI specification,[1] as supported by the DBI module, in a way that is meaningful for that database.
DBI offers two useful methods for querying which data sources are available to you for each driver you have installed on your system.
DBI sports an extremely useful ability to generate runtime tracing information of what it's doing, which can be a huge time-saver when trying to track down strange problems in your DBI programs.

 eXtropia | Tutorials | Introduction to Databases for the Web | The DBI API
Once, the DBI module is loaded, you can then instantiate a database connection.
Establishing a connection involves creating a "database handle" object by using DBI to connect to a database given a data source name, database user, database password, and a database driver.
Further, fantastic documentation for DBI can be found at http://www.symbolstone.org/.

The DBI is also responsible for the dynamic loading of drivers, error checking and handling, providing default implementations for methods, and many other non-database specific duties.
The DBI itself does not mandate or require any particular language to be used; it is language independent.
If the DBI is built using a Perl that has threads enabled then it will use a per-driver mutex to ensure that only one thread is with a driver at any one time.

 Amazon.com: Programming the Perl DBI: Books: Tim Bunce,Alistair Carty   (Site not responding. Last check: 2007-11-03)
Obviously, it describes the core DBI functionality very clearly, but it also contains a lot of information that was not previously available in a form comparable to what is in the book.
It is a pity that the use of DBI with the Apache web server and mod_perl is not covered at all, but even that would be difficult to do sensibly.
Having the DBI specification printed in book format is worth the price of the book alone; the rest of the material is also very valuable.

 Perl and Databases
In fact, when I refer to DBI throughout this discussion, I will actually be referring to the two in tandem, since you cannot do much with just the DBI.
The DBI defines the interface through which you can talk to the individual DBDs, which are often implemented in C using the client libraries distributed with a SQL database.
While the DBI defines an interface, a DBD interacts directly with a database so all the difficulties that come with different platforms and different levels of application support exist in full force.

DBI is a database-independent package that provides a consistent set of routines regardless of what database product is actually in use--Oracle, Sybase, Ingres, Informix, you name it.
I have been using the Perl DBI module for nearly 4 years relying mainly on the module documentation.
(For example: the purpose and relationship between the DBI layer and drivers, as well as the DBI objects, methods and attributes.) Personally, I appreciated the comparison of DBI and ODBC which was very informative.

Use the format name 'DBI', and instead of a filename, pass the ad_import call a connection in whatever database you are using, and specify a SQL SELECT statement:
The format 'DBI' (any DBI accessible database) may be used as the source of a conversion, but not as the target of a conversion.

Covered here are the very basic steps needed to, connect to the database server, test the connection, create a new table, add data to it, edit data stored and finally perform simple searches.
Which while on the subject the installation can be a little complex for those who are not that familiar with Perl, so you are strongly recommended to install it via its Bundle which makes life easier by installing the dependencies for you.
Once you have installed the DBI you need to have access to some form of database server to talk to, which in my case is MySQL although you can use more or less anything that has a DBI driver available.

 DBI - Database independent interface for Perl
This is the DBI specification that corresponds to the DBI version 1.06 ($Date: 1999/01/06 13:07:22 $).
It is strongly recommended that you use just one private attribute (e.g., use a hash ref) and give it a long and unambiguous name that includes the module or application that the attribute relates to (e.g., 'private_YourFullModuleName_thingy').
With RaiseError set the DBI will automatically die if any DBI method call on that handle (or a child handle) fails, so you don't have to test the return value of each method call.
