Here is something that completes without errors. I canoot vouch for
that it make much sense, though. I have not looked very much into
partitioned tables myself.


CREATE PARTITION FUNCTION partfun(int) AS
RANGE FOR VALUES ()
go
CREATE PARTITION SCHEME psX AS PARTITION partfun TO ([PRIMARY])
go
create table part_table (
col1 int NOT NULL,
col2 datetime NOT NULL,
weekno AS datepart(dayofyear, col2) / 7 + 1 PERSISTED,
PRIMARY KEY(weekno, col1)
) on psX (weekno)
go
drop table part_table
drop partition scheme psX
go
drop partition function partfun
