Как вернуть столбцы как имена элементов вместо элементов полей с атрибутами name

Я экспортирую данные из SQL Server в XML с конечной целью преобразования их в XSLT. Я хотел бы иметь возможность использовать экспортированные данные и ссылаться на них по имени элемента. Вывод моих данных XML выглядит следующим образом: 

<field name="InvoiceNo">641718</field>

Я бы хотел, чтобы вместо этого было имя элемента: 

<InvoiceNo>641718</InvoiceNo>

У меня есть 3 функции. Функция, которая создает заголовок, один для деталей и один, который экспортирует весь счет в XML.

Вот функция, которая создает XML. Я пробовал разные варианты, чтобы заставить это работать, но я не мог придумать правильный синтаксис. Это, конечно, предполагает, что внесение этого изменения сейчас облегчит выполнение XSLT в будущем, если потребуются дополнительные преобразования. В противном случае я мог бы использовать что-то вроде field[@name = "CustomerPO"] в моем XSL.

Если вы просто запросите вашу таблицу как можно проще, вы получите то, что вы хотите.

Попробуйте что-то вроде этого. 

declare @T table
(
  InvoiceNo int,
  SONo int
)

insert into @T values
(641718, 1),
(641719, 2)

select InvoiceNo,
       SONo
from @T
for xml path('header'), root('invoice')

Результат: 

<invoice>
  <header>
    <InvoiceNo>641718</InvoiceNo>
    <SONo>1</SONo>
  </header>
  <header>
    <InvoiceNo>641719</InvoiceNo>
    <SONo>2</SONo>
  </header>
</invoice>
