According to BOL, the return value of sp_xml_removedocument is 0 for success and >1 for failure.
I tried on three different servers, it always returns 1.
Can anyone try the following test?
DECLARE @hdoc int
DECLARE @Rtn int
DECLARE @doc nvarchar(1000)
SELECT @hdoc=0,@Rtn=-1
SET @doc =N'
<ROOT>
<Customer CustomerID="VINET" ContactName="Paul Henriot">
   <Order CustomerID="VINET" EmployeeID="5" OrderDate="1996-07-04T00:00:00">
      <OrderDetail OrderID="10248" ProductID="11" Quantity="12"/>
      <OrderDetail OrderID="10248" ProductID="42" Quantity="10"/>
   </Order>
</Customer>
<Customer CustomerID="LILAS" ContactName="Carlos Gonzlez">
   <Order CustomerID="LILAS" EmployeeID="3" OrderDate="1996-08-16T00:00:00">
      <OrderDetail OrderID="10283" ProductID="72" Quantity="3"/>
   </Order>
</Customer>
</ROOT>'
--Create an internal representation of the XML document.
EXEC @Rtn=sp_xml_preparedocument @hdoc OUTPUT, @doc
IF @@ERROR=0
BEGIN
PRINT 'The return value for sp_xml_preparedocument is '+CAST(@Rtn as nvarchar(50))+N'. The handle is '+CAST(@hdoc as nvarchar(50))
END
DECLARE @Dummy nvarchar(20)
SELECT   @Dummy = CustomerID
FROM       OPENXML (@hdoc, '/ROOT/Customer',1)
            WITH (CustomerID nvarchar(10),
                  ContactName nvarchar(20))
-- Remove the internal representation.
SET @Rtn=-1
exec @Rtn=sp_xml_removedocument @hdoc
IF @@ERROR=0
BEGIN
PRINT 'The return value for sp_xml_removedocument is '+CAST(@Rtn as nvarchar(50))
END

Tried it with the same result - also tried on some code we've been using loads (with no problems, fingers crossed ) and that returns a 1 as well.

Found this link on google groups

http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&threadm=%23F2YsF6wAHA.1400%40tkmsftngp05&rnum=2&prev=/groups%3Fq%3Dsp_xml_preparedocument%2Breturns%2B1%26hl%3Den%26sourceid%3Dmozilla-search%26start%3D0%26start%3D0

which indicates this is a bug and it always returns 1.

I tried putting in a duff handle to remove and you do seem to be able to check @@ERROR to see if it fails though.

Thanks for your input. It seems it's a MS bug. Just check @@Error should workaround. Thanks again.
