Question

我目前有六个查询，我在其中查看结果并使用电子表格计算两个不同的最终百分比。我相信它可以在一个查询中完成，并且没有电子表格，但我在SQL中不够了解它。我希望在这里有来自神奇的SQL神的方向。

我们有多个地点，并根据其他两个百分比的平均值计算每个地点的过期时间百分比和过期时间辐射百分比：

过期美元÷预计美元= 过期浮动％
过期单位÷总有效单位= 过期单位％
（过期的单位％ + 过期的美元％）/ 2 = 过期的％

Fallout使用相同的计算，但会查看明天的金额。

已解决：我花时间了解子查询，并由STID加入。感谢所有协助并帮助指导我的人正确的方向。

这是我的最终代码：

SET DATEFIRST 1;
DECLARE @Today date = dbo.getdateparam(92,999);
DECLARE @TodayNum int = DATEPART(dw, @Today);
DECLARE @Saturday date = DATEADD(DAY, (6-@TodayNum)%7, @Today);
DECLARE @PrevSat date = DATEADD(DAY, -7, @Saturday);

Answer 1

您永远不会将变量设置为任何实际值，您将继续在无关的SELECT语句中选择无用变量。

在以下一行

Set @pdD = Sum( Case When a.DueDate < GetDate() Then DateDiff(d,a.DueDate,@runDate) * (a.WeeklyRate/7) )

您没有说明s.DueDate的来源。它甚至不会编译。

在此SELECT中，该表完全不相关

Select a.STID as STID,
@pdU As PastDueUnits,
@activeU As ActiveUnits,
@pdD As PastDueDollars,
@projRent As ProjRent,
@pdP As PastDuePerc,
@foU As FalloutUnits,
@foD As FalloutDollars,
@foP As FalloutPerc

FROM Agreemnt a INNER JOIN CashProj on a.STID = CashProj.STID JOIN Invntry i ON a.STID = i.STID JOIN AgreHist h On i.InvID = h.InvID And i.STID = h.STID INNER JOIN Agreemnt a On a.STID = h.STID AND a.AgreeID = h.AgreeID AND a.AStatID = h.AStatID 
WHERE a.RentToRent = 0 AND i.InvStatID = 11 AND i.DisposalDate IS NULL AND a.AStatID = 1 AND a.DueDate < DateAdd(d, @runDate, GetDate())
GROUP BY a.STID
ORDER BY a.STID

这是在尝试使用变量进行计算之前如何设置值的示例。

    DECLARE @dayNum INT;
SET @dayNum = datepart(dw, getdate());

Select Invntry.STID,
  @foU = COUNT(Invntry.StockNumber) 
From Invntry
  Inner Join AgreHist On Invntry.InvID = AgreHist.InvID And
    Invntry.STID = AgreHist.STID
  Inner Join Agreemnt On Agreemnt.STID = AgreHist.STID And Agreemnt.AgreeID =
    AgreHist.AgreeID And Agreemnt.AStatID = AgreHist.AStatID
Where Invntry.InvStatID = 11 And Invntry.DisposalDate Is Null And
  Agreemnt.AStatID = 1 And Agreemnt.DueDate < DateAdd(d, Case @dayNum When '1' Then -2 When '2' Then 1 When '3' Then 1 When '4' Then 1
    When '5' Then 1 When '6' Then 0 When '7' Then -1 End, GetDate()) And Agreemnt.RentToRent = 0
Group By Invntry.STID

Answer 2

你不能使用这样的变量，你不能在一个聚合查询中这样做，因为它会创建一个巨大的笛卡尔积，并给你不正确的结果。

您可以为列出的每个查询使用CTE或子查询，然后在STID上将它们连接在一起并应用您的公式。

...示例

/* declare all variables here */
DECLARE @dayNum INT;
SET @dayNum = datepart(dw, getdate());

with PastDueDollars as (
    select ... from ... group by STID
), ProjectedDollers as (
    select ... from ... group by STID
), PastDueUnits as (
    select ... from ... group by STID
), preFinal as (

    select
        PastDueDollarRatio = pdd.PastDueDollars / pd.ProjRent,
        PastDueUnitRatio = pdu.UnitsPD / tau.TotalActiveUnits
        /* add the other calculations */
    from
        PastDueDollars pdd
        inner join ProjectedDollers pd on pdd.STID = pd.STID
        inner join PastDueUnits pdu on pdu.STID = pd.STID
        /* join more CTEs */
)

select
    f.*,
    PastDueRatio = (f.PastDueDollarRatio + f.PastDueUnitRatio) / 2
    /* and so on for the other calculations of calculations... */
from
    preFinal f
