SQL服务器while循环不工作。只获得第一行

目前我正在创建一份报告，按月列出每个地区的增量，因此我可以在最后创建趋势线，以指示减少的增量模式。

这是我当前的代码，可以产生本周的增量。代码非常混乱，我现在还只是想获得正确的数字。

        , t2.descript

        , cast((case when min(t0.U_CG) - sum(isnull(sum(t3.[total Sales]),0)) over (partition by t0.cardcode order by datepart(ww,T3.DocDate)) > 0 then min(t0.U_CG) - sum(isnull(sum(t3.[total Sales]),0)) over (partition by t0.cardcode order by datepart(ww,T3.DocDate)) else 0 end) as int) as 'Delta'

这是当前的结果，本周的增量是第43周。

AL Delta    BC Delta    MS Delta    ONC Delta   ONE Delta   ONF Delta   ONN Delta   ONS Delta   ONW Delta   QCE Delta   QCW Delta

我想要做的是为今年的每个星期创建一个增量表。我试图做的是为此添加一个while循环，但它给出了与没有循环的结果相同的结果，因此只有当前一周的一行的增量。

我就这样做了

declare @i int
declare @cnt int
set @i = 36 
set @cnt = datepart(ww, getdate())

while @i =< @cnt
begin

    sum(case when T0.descript = 'AL' then T0.[Current Sales] else Null end) as 'AL Total'

这是我第一次在sql中使用循环。有人能告诉我哪里错了吗？

对不起，我不好意思， 预期的产出将是

特定周的某个地区的差异是通过将该地区内所有客户的负增量相加来计算的。所以我们说一个地区只有2个人。该地区的第一个人买了40000，但配额只有30000，那个人的三角洲是0，其他人买了200，他的配额是20000，总和是19800.我们不考虑积极的增量。因此，计算特定时间范围内的每个增量值，将配额减去每个区域中每个客户的当前年销售额，最小值为0。我在第一段代码中所做的是通过获取所有客户的文档日期的max（）来计算本周的增量摘要，并计算他们的运行总销售额，直到他们之前的文档日期（购买日期）并找到他们的三角洲。所以基本上第一段计算今天的Delta摘要，但我需要deltas直到上周，2周前，3周前，4周前........

有关如何在没有循环的情况下执行此操作的任何建议吗？

1 个答案:

答案 0 :(得分：0)

没有人会试着去理解这样的混乱。但循环是直截了当的

建议尝试将代码分成小块，以便于调试。

从这样的事情开始：

<强> SQL DEMO 

declare @i int
declare @cnt int
set @i = 0 
set @cnt = 10

While @i < @cnt
begin
    SELECT @i;
    set @i = @i+1;
end;
