将week_no上的SQL数据放入列中

Question

我想转置以下SQL结果：

A 总和 week_no
一 1 22
一 2 24

进入这样的表：

A week_22 week_23 week_24
一 1 0 2

我怎样才能在Oracle上实现这一目标？谢谢！ （我应该考虑多年的每周数据，因此构建案例不是一种选择）

Answer 1

大多数情况下，我对您的样本数据假设了这个查询，它将填补第n周的空白并转动结果集

Select A,[22] [week_22],[23] [week_23],[24] [week_24] from (
Select A,Sum,Weekno from Table 
UNION
Select * from ( 
SELECT  top 1 t1.A,'' AS Sum,t1.Weekno-1 AS Weekno
FROM     Table t1
LEFT OUTER JOIN 
         Table  t2 
ON       t2.Weekno=t1.Weekno-1 
WHERE    t2.Weekno IS NULL 
AND      t1.Weekno > 0     
ORDER BY t1.Weekno desc )T)TT
PIVOT (MAX(SUM) FOR WEEKNO IN ([22],[23],[24]))PVT
