Name
       DBIx::Connector::Driver::mysql - MySQL-specific connection interface

Description
       This subclass of DBIx::Connector::Driver provides MySQL-specific implementations of the following methods:

       "savepoint"
       "release"
       "rollback_to"

       It also modifies the connection attributes as follows:

       "mysql_auto_reconnect"
	   Will always be set to false. This is to prevent MySQL's auto-reconnection feature from interfering with DBIx::Connector's auto-
	   reconnection functionality in "fixup" mode.

Name
       DBIx::Connector::Driver - Database-specific connection interface

Description
       Some of the things that DBIx::Connector does are implemented differently by different drivers, or the official interface provided by the
       DBI may not be implemented for a particular driver. The driver-specific code therefore is encapsulated in this separate driver class.

       Most of the DBI drivers work uniformly, so in most cases the implementation provided here in DBIx::Connector::Driver will work just fine.
       It's only when something is different that a driver subclass needs to be added. In such a case, the subclass's name is the same as the DBI
       driver. For example the driver for DBD::Pg is DBIx::Connector::Driver::Pg and the driver for DBD::mysql is DBIx::Connector::Driver::mysql.

       If you're just a user of DBIx::Connector, you can ignore the driver classes.  DBIx::Connector uses them internally to do its magic, so you
       needn't worry about them.

Interface
       In case you need to implement a driver, here's the interface you can modify.

   Constructor
       "new"

	 my $driver = DBIx::Connector::Driver->new( $driver );

       Constructs and returns a driver object. Each driver class is implemented as a singleton, so the same driver object is always returned for
       the same driver.  The "driver" parameter should be a Perl DBI driver name, such as "Pg" for DBD::Pg or "SQLite" for DBD::SQLite. If a
       subclass has been defined for $driver, then the object will be of that class.  Otherwise it will be an instance of the driver base class.

   Instance Methods
       "ping"

	 $driver->ping($dbh);

       Calls "$dbh->ping". Override if for some reason the DBI driver doesn't do it right.

       "begin_work"

	 $driver->begin_work($dbh);

       Calls "$dbh->begin_work". Override if for some reason the DBI driver doesn't do it right.

       "commit"

	 $driver->commit($dbh);

       Calls "$dbh->commit". Override if for some reason the DBI driver doesn't do it right.

       "rollback"

	 $driver->rollback($dbh);

       Calls "$dbh->rollback". Override if for some reason the DBI driver doesn't do it right.

       "savepoint"

	 $driver->savepoint($dbh, $name);

       A no-op. Override if your database does in fact support savepoints. The driver subclass should create a savepoint with the given $name. See
       the implementations in DBIx::Connector::Driver::Pg and DBIx::Connector::Driver::Oracle for examples.

       "release"

	 $driver->release($dbh, $name);

       A no-op. Override if your database does in fact support savepoints. The driver subclass should release the savepoint with the given $name.
       See the implementations in DBIx::Connector::Driver::Pg and DBIx::Connector::Driver::Oracle for examples.

       "rollback_to"

	 $driver->rollback_to($dbh, $name);

       A no-op. Override if your database does in fact support savepoints. The driver subclass should rollback to the savepoint with the given
       $name. See the implementations in DBIx::Connector::Driver::Pg and DBIx::Connector::Driver::Oracle for examples.
