Question

我需要帮助从此XML中检索存储在SQL Server表的列中的数据。我一直在搜索问题库，但找不到与我相符的内容。也许我错过了某种方式。无论如何，这里存储的XML如何：

<ProductStructure>
  <Plans>Essential</Plans>
  <Plans>Standard</Plans>
  <Plans>Silver</Plans>
  <Plans>Gold</Plans>
  <Plans>Platinum</Plans>
  <Plans>Titanium</Plans>
  <Destinations>Region A</Destinations>
  <Destinations>Region B</Destinations>
  <Destinations>Region C</Destinations>
  <Destinations>Region D</Destinations>
  <InsuredTypes>One Person</InsuredTypes>
  <InsuredTypes>Couple</InsuredTypes>
  <InsuredTypes>Group</InsuredTypes>
</ProductStructure>

我想选择xml并在SQL中获得如下所示的输出：

|Plans          |Essential    |
|               |Standard     |
|               |Silver       |
|               |Gold         |
|               |Platinum     |
|               |Titanium     |
|---------------+-------------|
|Destinations   |Region A     |
|               |Region B     |
|               |Region C     |
|               |Region D     |
|---------------+-------------|
|InsuredTypes   |One Person   |
|               |Couple       |
|               |Group        |

很抱歉，如果这个问题看得很糟糕的话。谢谢。

DECLARE @xml xml = N'<ProductStructure>
  <Plans>Essential</Plans>
  <Plans>Standard</Plans>
  <Plans>Silver</Plans>
  <Plans>Gold</Plans>
  <Plans>Platinum</Plans>
  <Plans>Titanium</Plans>
  <Destinations>Region A</Destinations>
  <Destinations>Region B</Destinations>
  <Destinations>Region C</Destinations>
  <Destinations>Region D</Destinations>
  <InsuredTypes>One Person</InsuredTypes>
  <InsuredTypes>Couple</InsuredTypes>
  <InsuredTypes>Group</InsuredTypes>
</ProductStructure>'

SELECT
    t.value('local-name(.)','nvarchar(max)'),
    t.value('.','nvarchar(max)')
FROM @xml.nodes('ProductStructure/*') AS t(t)

你会得到：

-------------------- --------------------
Plans                Essential
Plans                Standard
Plans                Silver
Plans                Gold
Plans                Platinum
Plans                Titanium
Destinations         Region A
Destinations         Region B
Destinations         Region C
Destinations         Region D
InsuredTypes         One Person
InsuredTypes         Couple
InsuredTypes         Group

您可以根据需要对结果进行分组。
