用信息转置 Table

Question

我需要转置此视图（在 sql 中）

进入此视图：

有什么解决办法吗？

Answer 1

您可以使用 union all:

select location, planning_product, '2016-05-16' as MondayDate, [5/16/2016] as ROP
from t
union all
select location, planning_product, '2016-05-09' as MondayDate, [5/9/2016] as ROP
from t
union all
. . .

注意列名需要转义。一些数据库使用双引号，其他数据库使用反引号或方括号。

Answer 2

假设 table 名称是 Tab 并且您有以下 3 个日期（您可以用自己的日期替换它们）：[1/16/ 2015 年、[2015 年 2 月 16 日]、[2015 年 3 月 16 日]

WITH Unpivoted (PlanningProduct, Location, [Monday Date], ROP)
AS(
    SELECT PlanningProduct, Location, CONVERT(datetime,MondayDate) AS [Monday Date], ROP
    FROM 
        (SELECT Location, PlanningProduct, [1/16/2015], [2/16/2015], [3/16/2015] -- add your dates
        FROM Tab) pvt
    UNPIVOT
        (ROP FOR MondayDate IN ([1/16/2015], [2/16/2015], [3/16/2015])) AS unpvt -- add your dates
)
SELECT PlanningProduct, Location, [Monday Date], SUM(ROP) AS ROP
FROM Unpivoted
GROUP BY PlanningProduct, Location, [Monday Date]
