PIVOT

一、一列

SELECT MM,[2016-06],[2016-07],[2016-08],[2016-09],[2016-10],[2016-11],[2016-12]
FROM (SELECT 'TEU/CBM' AS MM,cbm,khrq FROM #tmp_result) AS ss 
    PIVOT ( 
	    sum(cbm) FOR khrq IN ([2016-06],[2016-07],[2016-08],[2016-09],[2016-10],[2016-11],[2016-12]) 
	   ) AS pp 
-- ****
-- 等同
-- ****
SELECT * 
FROM (SELECT 'TEU/CBM' AS MM,cbm,khrq FROM #tmp_result) AS ss     PIVOT (     sum(cbm) FOR khrq IN ([2016-06],[2016-07],[2016-08],[2016-09],[2016-10],[2016-11],[2016-12])    ) AS pp

二、多列(列固定)  

 思路:CMB union all USD union RMB

SELECT * FROM (SELECT 'TEU/CBM' AS MM,cbm,khrq FROM #tmp_result) AS ss
         PIVOT (
             
sum(cbm) FOR khrq IN ([2016-06],[2016-07],[2016-08],[2016-09],[2016-10],[2016-11],[2016-12])
             )
AS pp union all SELECT * FROM (SELECT '利润/USD' AS MM,cbm,khrq FROM #tmp_result) AS ss
         PIVOT (
             
sum(usd) FOR khrq IN ([2016-06],[2016-07],[2016-08],[2016-09],[2016-10],[2016-11],[2016-12])
             )
AS pp union all SELECT * FROM (SELECT '利润/RMB' AS MM,cbm,khrq FROM #tmp_result) AS ss
         PIVOT (
             sum(rmb) FOR khrq IN ([2016-06],[2016-07],[2016-08],[2016-09],[2016-10],[2016-11],[2016-12])
             )
AS pp

二、多列(列 bu 不 固定)

create table #tmp
(ID int,Item1 varchar(5),Number1 int,Number2 int)
 
insert into #tmp
 select 1,'A',10,1 union all
 select 1,'B',5,3 union all
 select 1,'A',3,2 union all
 select 2,'A',5,3 union all
 select 2,'B',1,2 union all
 select 2,'B',2,2
 
-- select * FROM #tmp
select ID,Item1+'('+c+')' 'c',v
into #tmp2 from
 (select ID,Item1,sum(Number1) 'Number1',sum(Number2) 'Number2'
  from #tmp
  group by ID,Item1) a unpivot(v for c in([Number1],[Number2])) u
-- select * FROM #tmp2

select ID,[A(Number1)],[A(Number2)],[B(Number1)],[B(Number2)] 
from (SELECT * FROM #tmp2) b pivot(max(v) for c in([A(Number1)],[A(Number2)],[B(Number1)],[B(Number2)])) p
