查询@xml变量以获取行集

Question

我有一个xml数据,如下所示.

DECLARE @XmlContent XML
SET @XmlContent = 
'<Entities>
<Entity type = "5">
      <item id ="1"/>
      <item id ="2"/>
      <item id ="2"/>
</Entity>
<Entity type = "6">
      <item id ="3"/>
      <item id ="4"/>
      <item id ="5"/>
</Entity>
</Entities>'

我想从中选择数据并以下列格式插入表格 -

------------
Type Id
------------
5     1
5     2
5     2
6     3
6     4
6     5

有人可以帮我在sql server中为此编写查询吗？

Answer 1

select
  ent.value('@type', 'int') as Type,
  row.value('@id', 'int') as ID
from
  @XmlContent.nodes('/Entities/Entity') foo(ent)
  cross apply ent.nodes('item') bar(row)
