我需要按月，县和程序生成支出清单和申请数量。到目前为止，我已经能够获得支出清单，但是我很难获得每月申请数量的清单。这是我到目前为止的查询，但申请数量不正确。
select
servicecounty AS County,
program,
sum(case when month(entrydate) = 1 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as January,
sum(case when month(entrydate) = 2 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as February,
sum(case when month(entrydate) = 3 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as March,
sum(case when month(entrydate) = 4 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as April,
sum(case when month(entrydate) = 5 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as May,

sum(case when month(entrydate) = 7 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as July,
sum(case when month(entrydate) = 8 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as August,

sum(case when month(entrydate) = 11 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as November,
sum(case when month(entrydate) = 12 and year(entrydate) = 2014 then totalpaymenttotal else 0 end) as December,
sum(case when month(entrydate) = 1 and year(entrydate) = 2015 then totalpaymenttotal else 0 end) as [January 15],
sum(case when month(entrydate) = 2 and year(entrydate) = 2015 then totalpaymenttotal else 0 end) as [February 15],

该表包含以下字段：ServiceCounty，TotalPaymentTotal，Program，ApplicationID，EntryDate
先谢谢您的帮助。
最佳答案
您在第二个子查询中的计数都返回相同的值。请记住，count()计算非NULL值的数量。并且，0不为空。
三种解决方案：
将count()更改为sum()，将then更改为then 1。
删除else。
将else 0更改为else NULL。
这些是我个人喜好的顺序。
