Answer 1

以下是解决方案：

Select my.Mydate, MAX(ThisWeekStart) as ThisWeekStart , SUM(oqty) as oqty,SUM(sqty) as sqty,item from
(Select DatePart(week,o.orderdate) as Mydate,
    dateadd(wk, datediff(wk, 0, o.orderdate), 0) as ThisWeekStart,
 o.qty as oqty, 0 as sqty,  o.item
FROM [order] o 
UNION
SELECT DatePart(week,s.suppliedon) as suppliedon,
dateadd(wk, datediff(wk, 0, s.suppliedon), 0) as ThisWeekStart,
 0 as oqty, s.qty as sqty, s.item
FROM supply s) as my
GROUP BY my.Mydate, item
