从SQL Server中的XML获取XML列

Question

I need to get table with Address XML column from XML.

Here is what I do:

DECLARE @Person xml='<Person PersonID="a1fee068-aad4-459b-8ea7-063975f17bed">
  <Address State="1" District="15" House="test" Additional="1" />
  <Address State="8" District="11" Region="12" Neighborhood="13" Block="14" House="75" Additional="somewhere" />
</Person>'

DECLARE @handle INT  
DECLARE @PrepareXmlStatus INT  
EXEC @PrepareXmlStatus= sp_xml_preparedocument @handle OUTPUT, @Person  

SELECT  *
FROM  
OPENXML(@handle, '/Person', 2)  
WITH (
    Address xml
)  
EXEC sp_xml_removedocument @handle 

The result is only first Address from the XML. I can't understand why....

Any suggestions how get all records with Address tag?

You can use a XML query like this:

 DECLARE @Person xml=' <Person PersonID="a1fee068-aad4-459b-8ea7-063975f17bed"> <Address State="1" District="15" House="test" Additional="1" /> <Address State="8" District="11" Region="12" Neighborhood="13" Block="14" House="75" Additional="somewhere" /> </Person>' SELECT data.value('./@State', 'int') as State, data.value('./@District', 'int') as District, data.value('./@House', 'nvarchar(50)') as House, data.value('./@Additional', 'nvarchar(50)') as Additional, data.value('./@Region', 'int') as Region, data.value('./@Neighborhood', 'int') as Neighborhood, data.value('./@Block', 'int') as Block FROM @Person.nodes('/Person/Address') AS t1(data); 

\nState |  District |  House |  Additional |  Region |  Neighborhood |  Block \n----: |  -------: |  :---- |  :--------- |  -----: |  -----------: |  ----: \n    1 |  15 |  test |  1 |  null |  null |  null \n    8 |  11 |  75 |  somewhere |  12 |  13 |  14 \n\n

If you want each Address block:

\n    SELECT data.query('.') \n    FROM @Person.nodes('/Person/Address') AS t1(data) \n    GO \n\n|  (No column name) | \n|  :------------------------------------------------------------------------------------------------------------- | \n|  <Address State="1" District="15" House="test" Additional="1" /> | \n|  <Address State="8" District="11" Region="12" Neighborhood="13" Block="14" House="75" Additional="somewhere" /> | \n
