Question

我在下面的select语句中使用了gridview数据源。我需要在ProjInstDate上计算累积列，如下所示。但是如果你看到结果，我会在同一天的累计总数上得到重复，这是有道理的。但我无法弄清楚的是如何在ProjInstDate上计算累积量，而是针对不同的JobID进行计算。我不确定select语句在这一点上应该是什么样的＆＃34;（t1.ProjectedInstDate＆gt; = t2.ProjectedInstDate）＆＃34;。我知道这就是问题，但我不确定如何正确地做我想做的事。

select t1.JobID
     , t1.JobName
     , t1.[JobDescription]
     , t1.JobType
     , Convert(varchar, t1.QuoteDate, 101) AS QuoteDate
     , t1.ProjectedInstDate
     , Convert(decimal(12, 0), t1.QuoteTotal) AS QuoteTotal
     , Convert(decimal(12, 0), t1.Prob) AS Prob
     , t1.Completed
     , t1.ProjectManager
     , Convert(decimal(12, 0), t1.ProjectedIncome) AS ProjectedIncome
     , sum(CASE WHEN t1.Completed != 'y' and t1.Prob != 0 
                then Convert(decimal(12, 0),t2.ProjectedIncome) 
                else null end) As CumulativeProjectedIncome
     , Convert(decimal(12, 1), sum(CASE WHEN t1.Completed != 'y' and t1.Prob != 0 
                                        then (t2.ProjectedIncome/1923) 
                                        else null end)) as DAYSOFWORK
     , (CASE WHEN t1.Completed != 'y'and t1.Prob != 0 
             then Convert(decimal(12, 0), (datediff(day, GetDate(), t1.ProjectedInstDate))) 
             else null end) AS DAYSFROMTODAY 
     , (CASE WHEN t1.Completed != 'y' and t1.Prob != 0 
             then Convert(decimal(12, 1), sum(t2.ProjectedIncome/1923)-datediff(day, GetDate(), t1.ProjectedInstDate)) 
             else null end) as DAYSOFREVASOFTODAY
  from ContractPlan t1 
 inner join 
       ContractPlan t2 
    on (t1.ProjectedInstDate >= t2.ProjectedInstDate) 
 where (t2.Completed = 'n' or t2.Completed = 'N') 
   and (t1.Completed = 'N' or t1.Completed = 'n')
 Group By  
       t1.JobID
     , t1.JobName
     , t1.[JobDescription]
     , t1.JobType
     , t1.QuoteDate
     , t1.ProjectedInstDate
     , t1.QuoteTotal
     , t1.Prob
     , t1.ProjectedIncome
     , t1.Completed
     , t1.ProjectManager 
 Order By 
       t1.ProjectedInstDate
