PIVOT表日期＆amp;年份数据显示sql server 2005

Question

这是我的查询

SELECT *
FROM (SELECT CurDate, YEAR(CurDate) AS orderyear, Warranty_Info
      FROM eod_main where year(CurDate)>=2009 and year(CurDate)<=2011) AS D
  PIVOT(SUM(Warranty_Info) FOR orderyear IN([2009],[2010],[2011])) AS P

以上查询返回数据但是CurDate返回日期是同月返回多个日期。

我希望SUM(Warranty_Info)每月和每年只返回一次

输出应该看起来像

Month     2009     2010    2011    2012   2013
-----     ----     ----    ----    ----   -----
1          10       0       11      32      98
2          20       10      21      11      44
3          0        224     33      77      31

我的查询中存在某种问题，这就是为什么它会在同一个月返回多个数据，如

请帮我解决问题。感谢

我建议使用Month()函数返回每个月的数值，而不是使用CurDate作为年，月，日的完整日期。这将允许您按月分组而不是完整日期：

SELECT dateMonth, [2009],[2010],[2011]
FROM 
(
  SELECT month(CurDate) dateMonth, 
    YEAR(CurDate) AS orderyear, Warranty_Info
  FROM eod_main 
  where year(CurDate)>=2009 
    and year(CurDate)<=2011
) AS D
PIVOT
(
  SUM(Warranty_Info) 
  FOR orderyear IN([2009],[2010],[2011])
) AS P;
