Answer 2

您可以使用PIVOT.

实现此目的

Fiddler Demo

CREATE TABLE Sample
(
    SiteCode VARCHAR(100),  
    Month VARCHAR(100),    
    Amount INT
)

INSERT INTO Sample VALUES('XX', 'Jan', 1000)
INSERT INTO Sample VALUES('XX', 'Jan', 3000)  
INSERT INTO Sample VALUES('XX', 'Apr', 3000)
INSERT INTO Sample VALUES('XX', 'Apr', 1000)

SELECT P.SiteCode, P.Jan AS MonthJan, P.Apr AS MonthApr FROM 
(
    SELECT *, 
     ROW_NUMBER() OVER (PARTITION BY [Month] ORDER BY [Month]) AS Num 
    FROM Sample
) AS A
PIVOT (MAX(A.Amount) FOR A.Month IN ([Jan], [Apr])) AS P
