Dbi drivers

DBIObject: a common base class for all DBI. DBIDriver: a base class representing overall DBMS properties. Typically generator functions instantiate the driver objects like RSQLite (), RPostgreSQL (), RMySQL () etc. DBIConnection: represents a connection to a specific database. About DBI. The DBI is the standard database interface module for Perl. It defines a set of methods, variables and conventions that provide a consistent database interface independent of the actual database being used. For compatibility with old DBI scripts, the driver can be specified by passing its name as the fourth argument to connect (instead of \%attr): $dbh = DBI-connect($data_source, $user, $pass, $driver); In this "old-style" form of connect, the $data_source should not start with "dbi:driver_name:". (If it does, the embedded driver_name will be ignored).

use DBI; $dbh = DBI-connect("dbi:Oracle:$dbname", $user, $passwd); $dbh = DBI-connect("dbi:Oracle:host=$host;sid=$sid", $user, $passwd); # See the DBI module documentation for full details # for some advanced uses you may need Oracle type values: use DBD::Oracle qw(:ora_types);. There are four main DBI classes. Three which are each extended by individual database backends: DBIObject: a common base class for all DBI. DBIDriver: a base class representing overall DBMS properties. Typically generator functions instantiate the driver objects like RSQLite (), RPostgreSQL (), RMySQL () etc. DBD::Oracle - Oracle database driver for the DBI module. SYNOPSIS. use DBI; $dbh = DBI-connect("dbi:Oracle:$dbname", $user, $passwd); $dbh = DBI-connect("dbi:Oracle:host=$host;sid=$sid", $user, $passwd); # See the DBI module documentation for full details.

The drivers for both MySQL and PostgreSQL are in libdbi-dbd-mysql. If these are not installed, NXLog will return a libdbi driver initialization error. We encourage users to test the software and provide feedback. New in This Release. The latest additions to the Ingres DBI driver bring the driver to. DBI is a database-independent interface for the Perl programming language. DBD::mysql is the driver for connecting to MySQL database servers with DBI.
