	args := []interface{}{}
	s := `select a.name as name, b.name as ctype,a.max_length,a.precision,a.scale

	rows, err := db.DB().Query(s, args...)
	if err != nil {
		return nil, nil, err

		var name, ctype, precision, scale string
		var maxLen int
		err = rows.Scan(&name, &ctype, &maxLen, &precision, &scale)
		if err != nil {
			return nil, nil, err
