i have a stored proc that takes an xml string that is like <param @operation="ins" @data="test" />

but using this is problematic because i cant validate any params as they are all strings...

using sql parameters would have at least given me strong data types...

im lookign to regain this by using an xml like this and want to know how to extract the xml data for use in my stored procs and to come up with a simple xml layout to make extracting the data from the xml simple in SQL proc.


<param>
    <operation>ins</operation>
    <data>some data here</data>
</param>

Please see attached code:
CREATE PROCEDURE dbo.my_XML_update
	@XMLData NTEXT,
	@myId SMALLINT
AS
SET NOCOUNT ON

-- Retrieve XML data
DECLARE @hocDoc INT

DECLARE @Comments NVARCHAR(2048)

EXEC SP_XML_PREPAREDOCUMENT @hocDoc OUTPUT, @XMLData 

-- OPEN XML 
-- Param1 is Pointer to DOC
-- Param2 is XML doc hiearchy
-- Param3 is Use Element Structure rather than Attributes


SELECT
	ContactId,
	ContactName
INTO 
	#tmpContact
FROM 
	OPENXML(@hocDoc, '/root/Contact', 2) 
WITH (ContactId  INTEGER, ContactName NVARCHAR(50))

--this is how you populate the contact xml
SELECT Contact.ContactId,
		ISNULL(Contact.ContactName, '') AS ContactName
FROM #tmpContact Contact, Contact C
WHERE	Contact.ContactId = C.Id
ORDER BY	Contact.ContactName
FOR XML AUTO, ELEMENTS

-- Then you can do an INSERT
INSERT INTO Contact (Id, ContactName)
	SELECT ContactId,ContactName 
	FROM #tmpContact 

--or an UPDATE 
UPDATE Contact SET ContactName = t.ContactName 
FROM #tmpContact t
			WHERE	contact.Id = #tmpContact.ContactId 
		
-- Drop the temp Table
DROP TABLE #tmpContact

-- and MUST release XML doc to avoid memeory issues
EXEC SP_XML_REMOVEDOCUMENT @hocDoc
GO
