I'm trying to list tables / columns but can't access required list_tables / list_columns methods?
Error - Database method Fuel\Core\Database_PDO_Connection::list_columns is not supported by Fuel\Core\Database_PDO_Connection in COREPATH/classes/database/pdo/connection.php on line 191
The current FuelPHP PDO driver is a generic driver, so all methods that would result in RDBMS specific SQL are not implemented.
There is a redesign of the Database drivers on the roadmap for v2.0, which will support platform specific SQL, and will be completely based on the PDO driver.
