            //I add this block to avoid exception
            if( !in_array($config['driver'],['sqlite'])){
                $this->pdo->exec("SET NAMES '" . $config['charset'] . "' COLLATE '" . $config['collation'] . "'");
                $this->pdo->exec("SET CHARACTER SET '" . $config['charset'] . "'");
            }
