Question

嗨我有结构表

display_order   period_to_date  from_date   thru_date   beginning_market_value  net_flows   net_capital_gain    net_income  ending_market_value net_invested_capital    inv_progress

我希望将输出显示为

               MTD             QTD          YTD   INCP
from_date   03/31/2015  03/31/2015  12/31/2014  05/09/2002
thru_date   04/30/2015  04/30/2015  04/30/2015  04/30/2015
beginning_market_value  36812682.75 36812682.75 36943568.78  14,760,256.05

net_capital_gain    139045.6376 139045.6376 558539.325  16969340.37
net_income  51236.84278 51236.84278 251239.695  9257762.809
ending_market_value 36244861.29 36244861.29 36244861.29  36,244,861.29 
net_invested_capital    36054578.81 36054578.81 35435082.27  10,017,758.10 
inv_progress    190282.4803 190282.4803 809779.02    26,227,103.18

但是我无法得到这个结果..我正在使用的是

select category,
  max(case when period_to_date = 'MTD' then value end) [MTD],
  max(case when period_to_date = 'QTD' then value end) [QTD],
  max(case when period_to_date = 'MTD' then value end) [YTD],
  max(case when period_to_date = 'MTD' then value end) [INCP]
from
(
  --select period_to_date, from_date value, 'from_date' category
  --from transtable
  --union all
  --select period_to_date, thru_date value, 'thru_date' category
  --from transtable
  --union all
  select period_to_date, beginning_market_value value, 'beginning_market_value' category
  from transtable
  union all
  select period_to_date, net_flows value, 'net_flows' category
  from transtable
  union all
  select period_to_date, net_capital_gain value, 'net_capital_gain' category
  from transtable
  union all
  select period_to_date, net_income value, 'net_income' category
  from transtable
  union all
  select period_to_date, ending_market_value value, 'ending_market_value' category
  from transtable
  union all
  select period_to_date, net_invested_capital value, 'net_invested_capital' category
  from transtable
  union all
  select period_to_date, inv_progress value, 'inv_progress' category
  from transtable
) un
group by category

但它没有给出正确的结果..它显示所有4列的相同值

category    MTD QTD YTD INCP
beginning_market_value  36812682.7481145    36812682.7481145    36812682.7481145    36812682.7481145

我如何达到预期的效果？提前致谢

尝试这样的事情......

SELECT * FROM 
(
SELECT  CAST(period_to_date         AS VARCHAR(20)) AS period_to_date
        ,CAST(from_date             AS VARCHAR(20)) AS from_date
        ,CAST(thru_date             AS VARCHAR(20)) AS thru_date
        ,CAST(beginning_market_value AS VARCHAR(20))    AS  beginning_market_value
        ,CAST(net_flows             AS VARCHAR(20)) AS net_flows
        ,CAST(net_capital_gain      AS VARCHAR(20)) AS net_capital_gain
        ,CAST(net_income            AS VARCHAR(20)) AS net_income
        ,CAST(ending_market_value   AS VARCHAR(20)) AS ending_market_value
        ,CAST(net_invested_capital  AS VARCHAR(20)) AS net_invested_capital
        ,CAST(inv_progress          AS VARCHAR(20)) AS inv_progress
FROM TableName)T
  UNPIVOT (Vals FOR Category IN (from_date,thru_date,beginning_market_value,net_flows,net_capital_gain
                         ,net_income,ending_market_value,net_invested_capital,inv_progress)
          )up
  PIVOT (MAX(Vals)
         FOR period_to_date IN (MTD, QTD,YTD,INCP)
         )P

SQl查询将列拆分为行
