This module finds a DateTime::Format::* class that is suitable for the use with a given DBI connection (and DBD::* driver).

It currently supports the following drivers: MySQL, PostgreSQL (Pg).



DateTime::Format::DBI is just a front-end factory that will return one of the format classes based on the nature of your $dbh.

For information on the interface of the returned parser object, please see the documentation for the class pertaining to your particular $dbh.

In general, parser classes for databases will implement the following methods. For more information on the exact behaviour of these methods, see the documentation of the parser class.

Parser/formatter classes may additionally define methods like parse_type or format_type (where type is derived from the SQL type); please see the documentation of the individual format class for more information.


Support for this module is provided via the email list. See for more details.
