SQL数据透视表不起作用

Question

SQL 2005

I have a temp table:

 Year         PercentMale   PercentFemale  PercentHmlss   PercentEmployed  TotalSrvd
 2008           100                0           0              100              1
 2009           55                40           0               80             20
 2010           64                35           0               67            162
 2011           69                27           0               34            285
 2012           56                43          10                1             58

and I want to create a query to display the data like this:

                    2008    2009    2010    2011    2012
 PercentMale         100     55      64      69      56 
 PercentFemale        -      40      35      27      43 
 PercentHmlss         -      -       -       -       10 
 PercentEmployed     100     80      67      34      1 
 TotalSrvd            1      20     162     285      58 

Can I use a pivot table to accomplish this? If so, how? I've tried using a pivot but have found no success.

 select PercentHmlss,PercentMale,Percentfemale,
     PercentEmployed,[2008],[2009],[2010],[2011],[2012] from 

 (select PercentHmlss,PercentMale, Percentfemale, PercentEmployed,
     TotalSrvd,year from @TempTable)as T

  pivot (sum (TotalSrvd) for year 
     in ([2008],[2009],[2010],[2011],[2012])) as pvt

This is the result:

 PercentHmlss   PercentMale     Percentfemale PercentEmployed [2008]  [2009]    [2010]      [2011]   [2012]
    0               55              40            80           NULL     20      NULL         NULL     NULL
    0               64              35            67           NULL    NULL     162            NULL  NULL
    0               69              27            34           NULL    NULL     NULL          285     NULL
    0              100               0           100             1     NULL     NULL         NULL    NULL
   10               56              43             1           NULL    NULL     NULL         NULL     58

Thanks.

For this to work you will want to perform an UNPIVOT and then a PIVOT

SELECT *
from
(
  select year, quantity, type
  from 
  (
    select year, percentmale, percentfemale, percenthmlss, percentemployed, totalsrvd
    from t
  ) x
  UNPIVOT 
  (
    quantity for type
    in 
    ([percentmale]
     , [percentfemale]
     , [percenthmlss]
     , [percentemployed]
     , [totalsrvd])
  ) u
) x1
pivot
(
  sum(quantity)
  for Year in ([2008], [2009], [2010], [2011], [2012])
) p

See a SQL Fiddle with a Demo

Edit Further explanation:

You were close with your PIVOT query that you tried, in that you got the data for the Year in the column format that you wanted. However, since you want the data that was contained in the columns initially percentmale , percentfemale , etc in the row of data - you need to unpivot the data first.

Basically, what you are doing is taking the original data and placing it all in rows based on the year. The UNPIVOT is going to place your data in the format ( Demo ):

Year    Quantity    Type
2008    100         percentmale
2008    0           percentfemale
etc

Once you have transformed the data into this format, then you can perform the PIVOT to get the result you want.
