Question

我有一个为我们构建的SP，它在我们的数据库中执行表的摘要声明。我想要做的是让SP也根据输入的日期提取去年/月的数据。下面是我正在使用的SQL代码。我想要得到的是总和和体积字段，它是根据输入的日期参数减去1个月的总和。

例如：如果我将2013年10月1日开始和2013年10月31日结束，我将获得2013-10-01至2013-10-31的总数和数量，并在2个单独的栏中将2013-09-01至1013-的总数和数量09-30

首先声明并初始化上个月的开始日期。

DECLARE @PrevStart datetime 
SELECT @PrevStart = dateadd(month, -1, @Start)

在WHERE子句中，将上一个开始日期替换为开始日期，以便包含上个月的数据以及本月的数据。

and edi.Creation_dt >= convert(varchar,@PrevStart,112)
and edi.Creation_dt <= convert(varchar,@End,112)

然后使用CASE语句逻辑过滤本月的上个月数据。

  , max( case       when la.class_ty_cd = 'COMM' and th.ppa_in = 'N' and th.trans_sub_ty_cd = 'FEES'
                        AND edi.Creation_dt >= convert(varchar,@Start,112) then th.trans_qty 
                    when la.class_ty_cd = 'MUNI' and th.ppa_in = 'N' and th.trans_sub_ty_cd = 'EXCS'
                        AND edi.Creation_dt >= convert(varchar,@Start,112) then th.trans_qty
                    when la.class_ty_cd <> 'COMM' and th.ppa_in = 'N' and th.trans_sub_ty_cd = 'BASE'
                        AND edi.Creation_dt >= convert(varchar,@Start,112) then th.trans_qty
                    else 0 end) as Volume

  , sum(CASE WHEN edi.Creation_dt >= convert(varchar,@Start,112) THEN th.trans_am ELSE 0 END) as Total

  , max( case       when la.class_ty_cd = 'COMM' and th.ppa_in = 'N' and th.trans_sub_ty_cd = 'FEES'
                        AND edi.Creation_dt < convert(varchar,@Start,112) then th.trans_qty 
                    when la.class_ty_cd = 'MUNI' and th.ppa_in = 'N' and th.trans_sub_ty_cd = 'EXCS'
                        AND edi.Creation_dt < convert(varchar,@Start,112) then th.trans_qty
                    when la.class_ty_cd <> 'COMM' and th.ppa_in = 'N' and th.trans_sub_ty_cd = 'BASE'
                        AND edi.Creation_dt < convert(varchar,@Start,112) then th.trans_qty
                    else 0 end) as PrevVolume

  , sum(CASE WHEN edi.Creation_dt < convert(varchar,@Start,112) THEN th.trans_am ELSE 0 END) as PrevTotal

有人可以告诉我如何将这些字段添加到此存储过程
