DECLARE @t TABLE
    (
      ACCOUNTS NVARCHAR(MAX) ,
      YEAR INT ,
      REVENUE INT ,
      MARGIN INT
    )

INSERT  INTO @t
VALUES ('ACCOUNT1', 2012, 100, 50 ),('ACCOUNT1', 2013, 104, 52 ),
       ('ACCOUNT1', 2014, 108, 54 ),('ACCOUNT2', 2012, 112, 56 ),
       ('ACCOUNT2', 2013, 116, 58 ),('ACCOUNT2', 2014, 120, 60 ),
       ('ACCOUNT3', 2012, 124, 62 ),('ACCOUNT3', 2013, 128, 64 ),
       ('ACCOUNT3', 2014, 132, 66 )

;WITH CTE AS
(
  SELECT ACCOUNTS, value, name + '_' + cast(YEAR as char(4)) header
  FROM @t as p  
  UNPIVOT      
  (value FOR name IN           
  ([REVENUE], [MARGIN]) ) AS unpvt  
)
   SELECT ACCOUNTS, [REVENUE_2012],[REVENUE_2013],[REVENUE_2014]
         ,[MARGIN_2012],[MARGIN_2013],[MARGIN_2014] 
   FROM CTE
   PIVOT
   (SUM([value])  
   FOR header
   in([REVENUE_2012],[REVENUE_2013],[REVENUE_2014], [MARGIN_2012]
      ,[MARGIN_2013],[MARGIN_2014])  
   )AS p ORDER BY 2,3,4

结果:

ACCOUNTS REVENUE_2012 REVENUE_2013 REVENUE_2014 MARGIN_2012 MARGIN_2013 MARGIN_2014
ACCOUNT1 100          104          108          50          52          54
ACCOUNT2 112          116          120          56          58          60
ACCOUNT3 124          128          132          62          64          66
