In SQL Server 2005, this all works just fine. All you need to do is
access the scalar UDF with its 2-part name.

However, in SQL Server 2000 (the OP's platform), it doesn't work.
Calling it with the 2-part name gives the error "Incorrect syntax near
'.'", calling it with the 1-part name gives the error "Incorrect syntax
near '('.". Schemabinding doesn't make a difference.

Hi Gert-Jan,

I missed both the requirement of the OP that it run under SQL2000 and
the odd behaviour on that platform.

I can confirm the same behaviour here. And I can't find any explanation
in Books Online. I guess it's a bug - but not one I expect to ever see
fixed.

The workaround is of course simple:

DECLARE @d datetime
SET @d = dbo.get_current_quarter(GetDate())
SELECT id, dt
FROM (SELECT 1, CAST('20070701' AS datetime)
UNION ALL
SELECT 2, CAST('20070815' AS datetime)) AS t(id, dt)
WHERE dt IN (SELECT TheDate
FROM dbo.get_trxns_for_quarter(@d));
