sql - SQL SUM 混淆

Question

我为我的数据运行了以下查询：-

SELECT     CONTRACTNAME,
           AccountNo,
           TransDate, 
           JournalNo,
           AuditTrail,           
           Description,       
           CONTRACTNUMBER,
           GROUPING(CONTRACTNUMBER) as CONTRACTNUMBER,   
           SUM(PAFeebillamount)as Total  
FROM       SRVS.dbo.BTQGLDistributionsWithProjectCodesHM
WHERE      TransDate > '2012' AND CONTRACTNUMBER <> '00900'
GROUP BY   CONTRACTNAME,  
           AccountNo,   
           TransDate,
           JournalNo, 
           AuditTrail,    
           Description,      
           CONTRACTNUMBER with rollup  
ORDER BY   GROUPING (CONTRACTNUMBER) 

这给了我结果：-

我怎样才能改变这个，所以我得到每个合同号的单行总计。所以它看起来像下面的例子： -

此时此刻，我并不在意帐户编号/期刊编号等，因为它只是一个摘要。

只是在寻找有关按合同编号总结我的组的最佳方法的建议？

Answer 1

SELECT CONTRACTNAME, CONTRACTNUMBER, grouping(CONTRACTNUMBER) as CONTRACTNUMBER
SUM(PAFeebillamount)as Total
FROM SRVS.dbo.BTQGLDistributionsWithProjectCodesHM 
WHERE TransDate > '2012' AND CONTRACTNUMBER <> '00900' 
GROUP BY 
  CONTRACTNAME,
  CONTRACTNUMBER with rollup
ORDER BY GROUPING (CONTRACTNUMBER)

这应该为您提供每份合同的总数。您获得多个结果的原因是您正在对 contractName、Acct、Date、JournalNo、AuditTrail 和 Desc 进行分组。如果您想要一个完整的总数（每个合同号一个），那么您需要仅对合同号进行分组。

Answer 2

SELECT     CONTRACTNAME,
           '' AccountNo,
           '' TransDate, 
           '' JournalNo,
           '' AuditTrail,           
           '' Description,       
           CONTRACTNUMBER,
           GROUPING(CONTRACTNUMBER) as CONTRACTNUMBER,   
           SUM(PAFeebillamount)as Total  
FROM       SRVS.dbo.BTQGLDistributionsWithProjectCodesHM
WHERE      TransDate > '2012' AND CONTRACTNUMBER <> '00900'
GROUP BY   CONTRACTNAME,                  
           CONTRACTNUMBER with rollup  
ORDER BY   GROUPING (CONTRACTNUMBER) 

Answer 3

由于您不关心选择什么AccountNo, TransDate, etc，您可以将MAX其用作聚合函数，例如：

SELECT
  CONTRACTNAME, 
  MAX(AccountNo), 
  MAX(TransDate), 
  MAX(JournalNo),
  MAX(AuditTrail),
  MAX(Description),
  CONTRACTNUMBER, 
  GROUPING(CONTRACTNUMBER) as CONTRACTNUMBER, 
  SUM(PAFeebillamount)as Total
FROM SRVS.dbo.BTQGLDistributionsWithProjectCodesHM 
WHERE TransDate > '2012' 
  AND CONTRACTNUMBER <> '00900' 
GROUP BY 
  CONTRACTNAME,
  CONTRACTNUMBER with rollup
ORDER BY GROUPING (CONTRACTNUMBER)

如果您不想要它们，只需将它们从语句中删除，或用orSELECT替换它们：NULL''

SELECT
  CONTRACTNAME,
  CONTRACTNUMBER, 
  GROUPING(CONTRACTNUMBER) as CONTRACTNUMBER, 
  SUM(PAFeebillamount)as Total
FROM SRVS.dbo.BTQGLDistributionsWithProjectCodesHM 
WHERE TransDate > '2012' 
  AND CONTRACTNUMBER <> '00900' 
GROUP BY 
  CONTRACTNAME,
  CONTRACTNUMBER with rollup
ORDER BY GROUPING (CONTRACTNUMBER)
