INNER JOIN between a CLR-TVF and a table returns no rows

[h2reyes]

I have the following query:

select sq.*, p.numero, p.nombre
from paf p right outer join dbo.GetListOfSq uaresForShippin gLot(@lot) sq on sq.number = p.numero and sq.version = p.numero

The @lot parameter is declared at the top (declare @lot int; set @lot = 1;). GetListOfSquare sForShippingLot is a CLR TVF coded in C#. The TVF queries a XML field in the database and returns nodes as rows, and this is completed with information from a table.

If I run a query with the TVF only, it returns data; but if I try to join the TVF with a table, it returns empty, even when I'm expecting matches. I thought the problem was the data from the TVF was been streamed and that's why it could not be joined with the data from the table.

I tried to solve that problem by creating a T-SQL multiline TVF that is supposed to generate a temporary table. This didn't fix the problem.

What can I do? Does anybody know if I can force the TVF to render its data somewhere so the JOIN works? I was thinking a rowset function could help, but I just can't figure out how.

PLEASE HELP!!!!

Let me know if you want the code for the CLR TVF. This is the code for the T-SQL TVF:

CREATE FUNCTION [dbo].[GetTabListOfSqu aresForShipping Lot]
(
@ShippingLot int
)
RETURNS
@result TABLE
(
Number int, Version int, Position smallint,
SubModel smallint, Quantity smallint,
SquareId nvarchar(5),
ParentSquareId nvarchar(5),
IsSash smallint,
IsGlazingBead smallint,
Width float,
Height float,
GlassNumber smallint,
GlassWidth float,
GlassHeight float
)
AS
BEGIN
INSERT INTO @result
SELECT *
FROM dbo.GetListOfSq uaresForShippin gLot(@ShippingL ot)

RETURN
END
