SYNOPSIS

package foo;
use Meta::Db::Dbi qw();
my($object)=Meta::Db::Dbi->new();
my($result)=$object->do("CREATE DATABASE foo");

DESCRIPTION

This is my extension of the Dbi module. The reason that there is no inheritance here is that DBI is hard to inherit from since the object which is the database handle (which is returned from connect) is not clear (I mean which object is it). And all the internals of the other objects (statement handles and others) are not well documented. This is the reason that this object just stores a handle and not IS a handle.

FUNCTION DOCUMENTATION

new($)

This is a constructor which gives you a new Dbi object.

error($$)

This class method will handle error for us by raising an exception with the relevant errors data.

connect_dsn($$$)

connect_xml($$$$)

This method will receive: 0. A Meta::Db::Dbi object to connect. 1. A file name of XML data for connection. 2. A name of a connection to connect with. 3. A name of a database to connect to. The method will connect the Dbi object.

connect($$)

This will connect the Dbi to the specified connection data. The connection will NOT be to a specific database. Parameters: 0. Dbi object - handle of the object to connect. 1. Meta::Db::Connection object - used to get the connection information.

connect_def($$$)

TODO

-use Meta::Class::MethodMaker so that inheritance and code will be cleaner.

-use the connect_cached method of the DBI instead of straight connect.

-add convenience method of auto_commit on and off.
