我正在尝试将一行数据转换为包含单个对象的 JSON 数组。其中一列包含 XML，它概述了转换为数组的另一个单个对象。

我的查询：

WITH r AS (
SELECT TOP 1 * FROM Table1
ORDER BY RecordID ASC)

SELECT 
NEWID() AS 'Report.ReportUUID', 
Value1 as 'Report.Value1', 
Value2 as 'Report.Value2',
DateTime as 'Report.DateTime',
UserID as 'Report.UserID',
'Medium' as 'Report.Priority',
NEWID() as 'Report.Item.ItemUUID',
XML.value('category[1]', 'varchar(100)') as 'Report.Item.Category',
XML.value('description[1]', 'varchar(1000)') as 'Report.Item.Description',
XML.value('date[1]', 'varchar(100)') AS 'Report.Item.DateTime'
FROM r
FOR JSON PATH, ROOT('DataSet');

期望的输出：

{
  "DataSet" : {
    "Report" : [
      {
        "ReportUUID" : "uuid here",
        "Value1" : "value1",
        "Value2" : "value2",
        "DateTime" : …
