TSQL XML Query Question
Is this possible in TSQL?
I am feeding this structure in via an xml param. And I need to set it into a temp table.
DECLARE @xml xml
SET @xml = '<Events>
<Event id="8">
<Responses>
<Response id="59">
<Loe>
<Id>89</Id>
</Loe>
</Response>
<Response id="60">
<Loe>
<Id>89</Id>
<Id>90</Id>
<Id>88</Id>
<Id>87</Id>
</Loe>
</Response>
</Responses>
</Event>
</Events>';
Trying to display it like:
EventId ResponseId LoeId
8 59 89
8 60 89
8 60 90开发者_如何学Go
8 60 88
8 60 87
I tried to use this query, but it throws an error.
SELECT
[data].value('../../@id','varchar(100)') AS EventId,
[data].value('@id','varchar(100)') AS ResponseId,
[data].value('Loe/Id','varchar(100)') AS LoeId
FROM @xml.nodes('/Events/Event/Responses/Response') as Test([data])
But if I remove the LoeId it works and I get this:
EventId ResponseId
8 59
8 60
What I am doing wrong? How do I address the Loe->Id in the query?
I am using MSSQL 2008. Do you have any ideas?
Thanks.
this should do it:
SELECT
event.value('@id', 'int') AS Event,
response.value('@id','int') AS Response,
id.value('.','int') AS LoeId
FROM
@xml.nodes('Events/Event') AS t1(event) cross apply
t1.event.nodes('Responses/Response') AS t2(response) cross apply
t2.response.nodes('Loe/Id') AS t3(id)
ORDER BY Event, Response, LoeId
