我有一个功能,我在这里收到一个"由零错误发生的分区"信息。这是我的功能:

我认为这是一个错误,我开始划分以找到几个不同的列。大多数select语句都是相同的,除了最终的情况。所以我在这个领域猜测我遇到了这个问题:

CASE WHEN (CAST(A.Amount AS float) - ISNULL(B.Service1_Only_Amount, 0) - ISNULL(C.Service2_Sales, 0)) 
                          / (A.Total_Customers1 - ISNULL(B.Service1_Only_Customers1, 0)) BETWEEN @Tier1 AND @Tier2 THEN '1'

我已尝试将代码调整为:

CASE WHEN Coalesce((CAST(A.Amount AS float) - ISNULL(B.Service1_Only_Amount, 0) - ISNULL(C.Service2_Sales, 0)) 
                          / (A.Total_Customers1 - ISNULL(B.Service1_Only_Customers1, 0)) ,0)BETWEEN @Tier1 AND @Tier2 THEN '1'

我也尝试过:

CASE WHEN (CAST(A.Amount AS float) - ISNULL(B.Service1_Only_Amount, 0) - ISNULL(C.Service2_Sales, 0)) 
                          / (A.Total_Customers1 - NULLIF(B.Service1_Only_Customers1, 0)) BETWEEN @Tier1 AND @Tier2 THEN '1'

我的最后一次尝试是:

CASE WHEN Coalesce((CAST(A.Amount AS float) - ISNULL(B.Service1_Only_Amount, 0) - ISNULL(C.Service2_Sales, 0)) 
                          / (A.Total_Customers1 - ISNULL(B.Service1_Only_Customers1, 0)),0) BETWEEN @Tier1 AND @Tier2 THEN '1'

任何人都可以提供一些见解。我不知道会出现什么样的&#39; 0&#39;或者此时抛出异常。

1 个答案:

答案 0 :(得分:2)

当查询发生分割时会发生

Division by Zero error

select 1/0

使用NULLIF()功能来避免divide by zero exeption

division的所有语句更改为此类似的内容。

CASE WHEN (CAST(A.Amount AS float) - ISNULL(B.Service1_Only_Amount, 0) - ISNULL(C.Service2_Sales, 0)) 
                          / Nullif((A.Total_Customers1 - ISNULL(B.Service1_Only_Customers1, 0)) BETWEEN @Tier1 AND @Tier2 THEN '1',0)

此处Nullifdenominator nullzero
