XML Путь, извлечение данных из таблицы и с объединенными узлами

Question

Я пытался получить из моей таблицы файл XML в определенном формате.

Моя таблица следующая:

IF OBJECT_ID('TripHistoryTest','U') IS NOT NULL DROP TABLE TripHistoryTest
create table TripHistoryTest
(
    [BarCode] nvarchar(100),
    [PassengerName] nvarchar(100),
    [SegmentType] char(1),
    [Flight1_From] nvarchar(100),
    [Flight1_FromTime] nvarchar(100),
    [Flight1_To] nvarchar(100),
    [Flight1_ToTime] nvarchar(100),
    [Flight2_From] nvarchar(100),
    [Flight2_FromTime] nvarchar(100),
    [Flight2_To] nvarchar(100),
    [Flight2_ToTime] nvarchar(100),
    [Flight3_From] nvarchar(100),
    [Flight3_FromTime] nvarchar(100),
    [Flight3_To] nvarchar(100),
    [Flight3_ToTime] nvarchar(100),
    [Flight4_From] nvarchar(100),
    [Flight4_FromTime] nvarchar(100),
    [Flight4_To] nvarchar(100),
    [Flight4_ToTime] nvarchar(100),
    [Hotel_From] nvarchar(100),
    [Hotel_FromTime] nvarchar(100),
    [Hotel_To] nvarchar(100),
    [Hotel_ToTime] nvarchar(100),
    [Train_From] nvarchar(100),
    [Train_FromTime] nvarchar(100),
    [Train_To] nvarchar(100),
    [Train_ToTime] nvarchar(100),
    [Car_From] nvarchar(100),
    [Car_FromTime] nvarchar(100),
    [Car_To] nvarchar(100),
    [Car_ToTime] nvarchar(100)
)

insert into TripHistoryTest

Я имитирую то, что у меня есть в системе сейчас, поэтому вот несколько заметок:

SegmentType:

F: Рейс
T: Поезд
C: Автомобиль
H: Отель

Я сделал запрос, используя XML PATH, но безуспешно, вот мой вывод:

                and A.[BarCode] = B.[BarCode]

  </BARCODE>
</BARCODE_List>

Есть ли простой способ сделать это? Очевидно, что я хотел бы включить сегмент Hotel, Car и Train, поскольку они являются важной информацией.

Answer 1

Вот решение с использованием выражений XQuery и FLWOR. Все сегменты полета (F: полет) организованы в виде строк через UNION ALL. Конечный XML формируется непосредственно через выражения FLWOR.

Answer 2

Данные Flightfrom и Flightto. Они должны быть в нескольких строках, а не в нескольких столбцах, чтобы xml был сгенерирован в соответствии с запросом:
