Sql server mssql查询连接以根据折扣百分比计算折扣人员

嗨，我有下面的工作查询msql

select 
max(load_number) load_number,max(linediscount) maxlinediscount,max(CustomerBand) customer_band

  from [Linked_Order_lines] 
  join [Customer_Order_Summary]
  on [Customer_Order_Summary].[CustomerOrderID]=[Linked_Order_lines].[load_number]
  join [Customers]
  on Customers.CustomerName=Customer_Order_Summary.CustomerName
  join Customer_Order_lines
  on Customer_Order_Summary.CustomerOrderID=Customer_Order_lines.CustomerOrderID
  join price_escalation_bands
  on price_escalation_bands.band=Customer_Order_Summary.CustomerBand

  where [linked_order_id] in 
  (
    select [linkedorderid] from 
    [Linked_Order_Summary] join [Linked_Order_lines] on
    [Linked_Order_Summary].[linkedorderid] = [Linked_Order_lines].[linked_order_id]
    where [load_number]='7'
  ) 
  and Customer_Order_lines.linestatus='current'

    group by load_number

这就产生了结果

在这个查询中，我已经加入了price_escalation_bands表，如下所示：

我想做的是将查询中的maxlinediscount与表price\u escalation\u bands的折扣列进行比较，并返回表中下一个最大记录的用户id fk\u Salesian\u userid。因此，折扣11将转到折扣15，并返回fk_销售人员_用户ID 9。如果折扣是18，它将变为100，并返回fk_Sales_userid 21

我基本上是想计算出可以在maxlinediscount中批准折扣的fk_推销员_用户ID

因此，期望的输出是：

我是否需要case语句？如果需要，如何将其与现有select语句中的max语句一起使用

提前感谢，因为当您加入价格升级时，您可以使用另一个折扣条件。 检查一下。在这里，我在临时表中尝试了结果。通过传递maxlinediscount，您可以对加入价格\升级\带尝试相同的子查询。 希望这将对您有所帮助。

最终工作语法：

IF OBJECT_ID('tempdb..#linkloads') IS NOT NULL
BEGIN
DROP TABLE #linkloads
END

CREATE TABLE #linkloads
(
maxlinediscount [decimal](10,3),
customer_band [varchar](50),
load_number [int],
totalcost [decimal](10,3),
period [datetime],
CreditLimit[decimal](10,3),
CurrentBalance[decimal](10,3),
CustomerName [varchar](100),
TotalCubes[decimal](10,3),
TreatedCubes[decimal](10,3),
NormalCubes[decimal](10,3),
PricingIssue[bit]
);



insert into #linkloads

select max(linediscount) maxlinediscount,max(CustomerBand) customer_band,max(load_number) load_number,max(totalcost) totalcost,max(Customer_Order_Summary.PeriodStart) period,max(Customers.CreditLimit) CreditLimit ,max(Customers.CurrentBalance)CurrentBalance,max(Customer_Order_Summary.CustomerName)CustomerName,max(TotalCubes) TotalCubes,max(TreatedCubes)TreatedCubes ,max(TotalCubes-TreatedCubes) as NormalCubes,sum(case when pricingissue=1 THEN 1 ELSE 0 END) pricingissue

  from [Linked_Order_lines] 
  join [Customer_Order_Summary]
  on [Customer_Order_Summary].[CustomerOrderID]=[Linked_Order_lines].[load_number]
  join [Customers]
  on Customers.CustomerName=Customer_Order_Summary.CustomerName
  join Customer_Order_lines
  on Customer_Order_Summary.CustomerOrderID=Customer_Order_lines.CustomerOrderID
   where [linked_order_id] in 
  (
    select [linkedorderid] from 
    [Linked_Order_Summary] join [Linked_Order_lines] on
    [Linked_Order_Summary].[linkedorderid] = [Linked_Order_lines].[linked_order_id]
    where [load_number]='10'
  ) 
  and Customer_Order_lines.linestatus='current'
     group by load_number;

select * from #linkloads;

select load_number,maxlinediscount,customer_band,[Salesman_Discounts_per_band].fk_salesman_userid,totalcost,period,creditlimit,currentbalance,customername,totalcubes,treatedcubes,normalcubes,pricingissue from #linkloads
left outer JOIN [Salesman_Discounts_per_band] on [Salesman_Discounts_per_band].band=#linkloads.customer_band
AND [Salesman_Discounts_per_band].[discount_allowed] = (
  SELECT top 1 [Salesman_Discounts_per_band].[discount_allowed]
  FROM [Salesman_Discounts_per_band]
  WHERE [Salesman_Discounts_per_band].band=#linkloads.customer_band
  AND [Salesman_Discounts_per_band].[discount_allowed]<=#linkloads.maxlinediscount
  ORDER BY [Salesman_Discounts_per_band].[discount_allowed]
)
;

感谢Pradeeshnarayan，非常感谢。最后，如果没有临时表，我无法完成这项工作。
