我有一个功能，我在这里收到一个＆＃34;由零错误发生的分区＆＃34;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。
答案 0 :(得分：2)
Division by Zero error。
select 1/0
使用NULLIF()功能来避免divide by zero exeption
将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Nullif会denominator null为zero。
