public function Connection::ThrowPdoException in Drupal driver for SQL Server and SQL Azure 8.2

This is a helper method to rethrow an Exception if the execution of a PDOStatement fails.

Sometimes, as a result of a PDO Statement execution error the error itself will be found in the connection and no in the statement.
