Sql 折叠case语句返回数据？

我创建了一个查询，用于从发票表中提取年度销售总额，但当我运行该查询时，会得到大量0列和重复的行数据，因为不是每年都有，而且cust numb有销售。这是我的密码

SELECT * INTO #REVTEMP FROM
(
SELECT 

YEAR(CONVERT(CHAR(10), DATEADD(d, INVC_RDAT +5843, 0), 1)) [YEAR]
,ISNULL(b.BILLTO_NUMB,c.BILLTO_NUMB)[BILL TO NUMB]
,ISNULL(B.BILLTO_NAME, C.BILLTO_NAME) [CLIENT]
,SUM(CAST(NET_DLR AS MONEY)) [SALES REVENUE]

FROM placeholder.JR80 a
left outer join placeholder.DBO.JC10 b on b.JOB_NUMB = a.JOB_NUMB
left outer join placeholder.DBO.OE10 C ON C.ORD_NUMB = A.JOB_NUMB

 --where b.BILLTO_NUMB = 13651


 GROUP BY 
 b.BILLTO_NUMB
 ,C.BILLTO_NUMB
 ,YEAR(CONVERT(CHAR(10), DATEADD(d, INVC_RDAT +5843, 0), 1))
 ,B.BILLTO_NAME
 ,C.BILLTO_NAME

  --order by YEAR(CONVERT(CHAR(10), DATEADD(d, INVC_RDAT +5843, 0), 1))
  ) AS #REVETEMP

  SELECT 
    #REVTEMP.[BILL TO NUMB]
    ,CASE WHEN #REVTEMP.YEAR = 2006 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2006 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2007 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2007 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2008 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2008 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2009 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2009 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2010 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2010 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2011 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2011 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2012 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2012 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2013 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2013 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2014 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2014 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2015 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2015 REVENUE]
    ,CASE WHEN #REVTEMP.YEAR = 2016 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END AS [2016 REVENUE]

    FROM #REVTEMP

  DROP TABLE #REVTEMP

我的结果是这样的

我希望每个cust numb只有一行包含其所有数据。我想我可能想得太多了，但我不知道如何去掉多余的行

如果我了解您的要求，您需要一个分组，并汇总案例陈述（总和似乎是个好主意），因此：

SELECT 
    #REVTEMP.[BILL TO NUMB]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2006 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2006 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2007 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2007 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2008 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2008 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2009 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2009 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2010 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2010 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2011 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2011 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2012 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2012 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2013 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2013 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2014 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2014 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2015 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2015 REVENUE]
    ,sum(CASE WHEN #REVTEMP.YEAR = 2016 THEN #REVTEMP.[SALES REVENUE] ELSE 0 END) AS [2016 REVENUE]
    FROM #REVTEMP
group by #REVTEMP.[BILL TO NUMB]
