X和Y之间的货币价值？

Question

这是一个简单的过程在excel中使用vlookup与近似匹配，但由于某些原因，我无法使其与SQl一起工作，我确信我正在以这种方式执行此任何帮助，我们将不胜感激。这是我得到的结果的一个样本：

Player ID ADT   ADT Tier 
103   31.25  2 
112   6.03  6 
114  498.26  7 
117  1330.82  4 
131   10.01  NULL 

这里是一个样本应该是什么样子：

Player ID ADT   ADT Tier 
103   31.25  11 
112   6.03  NULL 
114  498.26  7 
117  1330.82  4 
131   10.01  NULL 

下面是我想使用的代码。

Select S.Meta_ID as "Player ID" 
,Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) as ADT 
,case 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '3500' and '1000000' then '1' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '2000' and '3499.99' then '2' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '1500' and '1999.99' then '3' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '1000' and '1499.99' then '4' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '750' and '999.99' then '5' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '500' and '749.99' then '6' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '300' and '499.99' then '7' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '150' and '299.99' then '8' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '75' and '149.99' then '9' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '40' and '74.99' then '10' 
    when cast(Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2)as varchar) between '15' and '39.99' then '11' 
    Else null 
End as "ADT Tier" 

From dbo.CDS_STATDAY as S 

Where S.GamingDate Between '06/1/2014' and '08/31/2014' 
    And S.IDType = 'P' 
    And S.StatType <> 'Poker' 

Group by S.Meta_ID

您正在使用varchar导致您的BETWEEN按字母顺序进行比较，这就是您的结果出错的原因。拆下投报表如下图所示：

Select S.Meta_ID as "Player ID" 
,Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) as ADT 
,case 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 3500 and 1000000 then 1 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 2000 and 3499.99 then 2 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 1500 and 1999.99 then 3 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 1000 and 1499.99 then 4 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 750 and 999.99 then 5 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 500 and 749.99 then 6 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 300 and 499.99 then 7 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 150 and 299.99 then 8 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 75 and 149.99 then 9 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 40 and 74.99 then 10 
    when Round(Sum(S.TWin)/Nullif(Count(Distinct S.GamingDate),0),2) between 15 and 39.99 then 11 
    Else null 
End as "ADT Tier" 

From dbo.CDS_STATDAY as S 

Where S.GamingDate Between '06/1/2014' and '08/31/2014' 
    And S.IDType = 'P' 
    And S.StatType <> 'Poker' 

Group by S.Meta_ID 

解释你所得到的结果，按字母顺序31.25是2000和3499.99之间，这就是为什么你在针对该行ADT价值得到2。
