Question

我必须在存储过程中为下面的场景编写一个计算。我写了下面的代码，请告诉我它是否正确或是否还有其他更好的方法来编写它。

NetWorth值有一些'x'值，我需要在以下条件下计算此'x'值的佣金

总净值高达5,000英镑 - 30％
总净值高达5,000.01英镑至20,000英镑 - 35％
总净值高达20,000.01英镑至50,000英镑 - 40％
总净值高达50,000.01英镑+ - 45％

例如

如果NetWorth为100000，则计算结果如下

对于100000的前5000，佣金是30％，即5000 * 0.30 = 1500剩余（95000）
对于95000的下一个20000，佣金是35％，即20000 * 0.35 = 7000剩余（75000）
对于75000的下一个50000，佣金是40％，即50000 * 0.40 = 20000剩余（25000）
左边25000佣金为45％i，e。，25000 * 0.45 = 11250

所有这些佣金的总数= point1 + point2 + point3 + point4 = 1500 + 7000 + 20000 + 11250 = 39750

下面是我编写的存储过程中的代码。如果可以改进，或者有任何其他方式可以写，请告诉我。

DECLARE @NetWorth DECIMAL(18, 2) 
DECLARE @InterMediateTier1Value DECIMAL(18, 2) 
DECLARE @InterMediateTier2Value DECIMAL(18, 2)

SET @NetWorth = 40000 

DECLARE @TotalCommission DECIMAL(18, 2) 

IF @NetWorth <= 5000 
  BEGIN 
      SET @InterMediateTier1Commission = @NetWorth * 0.30

   AND @NetWorth <= 50000 
  BEGIN 
      SET @InterMediateTier1Value = @NetWorth - 5000 
      SET @InterMediateTier1Commission = 5000 * 0.30 

      IF @InterMediateTier1Value > 20000 
        SET @RemainderValue = @InterMediateTier1Value - 20000 

      SET @RemainderCommission = @RemainderValue * 0.40 
      SET @InterMediateTier2Commission = 20000 * 0.35 
      SET @TotalCommission = @InterMediateTier1Commission 
                             + @InterMediateTier2Commission 
                             + @RemainderCommission 
  END 
ELSE IF @NetWorth > 50000 
  BEGIN 
      SET @InterMediateTier1Value = @NetWorth - 5000 
      SET @InterMediateTier1Commission = 5000 * 0.30 

      IF @InterMediateTier1Value > 20000 
        SET @RemainderValue = @InterMediateTier1Value - 20000 

      SET @InterMediateTier2Commission = 20000 * 0.35 

      IF @RemainderValue > 50000 
        SET @InterMediateTier4Value = @RemainderValue - 50000 

      SET @InterMediateTier3Commission = 50000 * 0.40 
      SET @RemainderCommission = @RemainderValue * 0.45 
      SET @TotalCommission = @InterMediateTier1Commission 
                             + @InterMediateTier2Commission 
                             + @InterMediateTier3Commission 
                             + @RemainderCommission 
  END 

SELECT @TotalCommission AS TotalCommission

Answer 1

是的，这可以改进。将“NetWorth”金额和佣金放在表中，然后使用SQL来完成工作：

declare @Comm table (
    NetworthLower float,
    NetWorthHigher float,
    Commission float
);

insert into @comm
    select 0, 5000, 0.30 union all
    select 5000, 20000, 0.35 union all
    select 20000, 50000, 0.4 union all
    select 50000, NULL, 0.45

declare @Value float = 8000;

select SUM(case when @Value >= c.NetWorthLower and @Value < coalesce(c.NetWorthHigher, @Value)
                then (@Value - c.NetWorthLower) * c.Commission
                when  @Value >= c.NetWorthLower
                then (c.NetWorthHigher - c.NetworthLower) * c.Commission
                else 0.0
           end)
from @Comm c

这也可以计算整个表格的佣金，而无需使用存储过程。

Answer 2

试试这个，我发现它适用于以下测试用例

TEST CASE 1：DECLARE @NetWorth DECIMAL（18,2）= 1000

TEST CASE 2：DECLARE @NetWorth DECIMAL（18,2）= 9999

TEST CASE 3：DECLARE @NetWorth DECIMAL（18,2）= 40000

TEST CASE 4：DECLARE @NetWorth DECIMAL（18,2）= 78000

<强>查询

DECLARE @NetWorth DECIMAL(18, 2)  = 488000  

SELECT TotalCommission = 
CONVERT(DECIMAL(18, 2),

    CASE WHEN @NetWorth <= 5000 THEN @NetWorth * 0.30 
            WHEN @NetWorth > 5000  AND @NetWorth <= 20000 THEN (5000 * 0.30) + (@NetWorth - 5000) * 0.35 
            WHEN @NetWorth > 20000 AND @NetWorth <= 50000 
                                THEN CASE WHEN ((@NetWorth - 5000) > 20000)
                                            THEN (5000 * 0.30)  + 
                                                (20000 * 0.35)  +  
                                                ((@NetWorth - 5000)- 20000)* 0.40
                                            ELSE (5000 * 0.30)+ (20000 * 0.35)
                                        END
        WHEN @NetWorth > 50000 
                                THEN CASE WHEN ((@NetWorth - 5000) > 20000)
                                            THEN (5000 * 0.30) +
                                                (20000 * 0.35) + 
                                                (50000 * 0.40) +
                                                ((@NetWorth - 5000) - 20000 )*0.45
                                            ELSE (5000 * 0.30) + (20000 * 0.35) + (50000 * 0.40)
                                    END


    END

希望这会有所帮助。如果它在任何情况下失败，请告诉我。
