Answer 1

這裏順序是解決方案：

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
