Pivot - 如何求和和计算结果

Question

我确信这是一个快速的方法，但是除了答案之外，我尝试了所有方法。我有一个工作正常的枢轴脚本，除了列中的结果，我需要除以 100。所以结果 / 100 脚本是

SELECT 
USERID AS UserId,APPOINTMENTDATE,
isnull ([1],0) as'other',isnull ([2],0) as 'Medicare'
FROM 
(SELECT invoices.USERID, APPOINTMENTDATE,
[total],PAYERCODE,users.LOCATIONID
FROM APPOINTMENTS
where 
APPOINTMENTDATE between '2017-01-22' and '2017-01-23'  
) AS SourceTable
PIVOT
(
Sum(total)
FOR PAYERCODE IN ([1], [2])
) AS PivotTable;

所以我想做的是： Sum(total) 更改为 Sum(total/100)

任何想法.. 干杯

添加此示例，因为它可以正常工作。这是小提琴：http://sqlfiddle.com/#!6/8eef1/1/0

您的示例代码的问题是您试图在表本身而不是 Pivot 上进行选择。您需要在“SourceTable”中定义列，然后透视 PayerCode，然后执行 Select * FROM (Sourcetable Pivottable)

 drop table TestingPivot     
 Create table TestingPivot
 ( Total INT,
  Payercode INT,
  LocationID INT,
  UserID INT,
  Name VARCHAR(100) )

   Insert into TestingPivot values(100, 1, 1, 1, 'Ryan')
   Insert into TestingPivot values(200, 2, 2, 2, 'Mike')
   Insert into TestingPivot values(300, 3, 3, 3, 'John')

  Select * from (
  Select Total/100 as NewTotal, PayerCode, UserID, LocationID, 
  case when PayerCode = 1 then 'Other'
       when PayerCode = 2 then 'Medicare'
       else ''
       end as Type


   from TestingPivot
       ) as t
       Pivot
       (
         Sum(NewTotal) 
         FOR PayerCode IN  ("1","2")
        ) as P;
