Does XML AUTO support what I am trying to do?
At present we have a denormalised database. ie
Name|NameID|EmployeeID|EmployeeType
I'm normalising the database to resolve the EmployeeID from the Employee table rather than the Name Table.
So we have a select at the moment
开发者_StackOverflow社区SELECT Name, NameID, EmployeeID, EmployeeType FROM Name
FOR XML AUTO
Which will output:
<Name Name='Fred' NameID='1' EmployeeID='1' EmployeeType='Manager'>
Now I have an INNER JOIN
SELECT Name, NameID, Name.EmployeeID, Employee.EmployeeType FROM Name
INNER JOIN Employee ON Name.EmployeeID = Employee.EmployeeID
FOR XML AUTO
Now my XML looks like this:
<Name Name='Fred' NameID='1' EmployeeID='1'>
<Employee EmployeeType='Manager' />
</Name>
My question is , is there any way to get XML AUTO to output my XML as before, or do i have to move to XML Explicit?
Can you use FOR XML PATH
instead?? It gives you a lot more control over the layout of your XML, and it's A LOT EASIER than XML EXPLICIT! :-)
SELECT
Name as '@Name',
NameID as '@NameID',
Name.EmployeeID as '@EmployeeID',
Employee.EmployeeType as '@EmployeeType'
FROM Name
INNER JOIN Employee ON Name.EmployeeID = Employee.EmployeeID
FOR XML PATH('Name')
The PATH('Name')
defines that the whole element should be a <Name>
element, and if you use alias for your columns with a leading @ then you'll get attributes (without the leading "@", you get subelements).
Check out the MSDN article on What's new in SQL Server 2005 XML for some more details and examples.
