Sql server 有没有办法确定哪一行代码有被零除的错误？
我遇到了一个被零除的错误，从SELECT语句的起始位置开始，但不确定错误的确切位置。我在有除法命令的地方放置了NULLIF，0，但仍然返回被零除的错误。有没有一种方法可以精确定位错误的触发位置Sql server 有没有办法确定哪一行代码有被零除的错误？,sql-server,Sql Server,我遇到了一个被零除的错误，从SELECT语句的起始位置开始，但不确定错误的确切位置。我在有除法命令的地方放置了NULLIF，0，但仍然返回被零除的错误。有没有一种方法可以精确定位错误的触发位置 drop table #tempMAINA SELECT a.COUNTRY_IBS --,a.[List_Price_Code] AS "LPC" ,a.[Item_Number] --,

我发现可以产生被零除的线： 在ASP处的利润率为ASP的% THEN或ELSE可能导致0 标价百分比变动比例 WHEN和ELSE都可能导致0
旁注-我是否只是为您搜索了每个/并找到了所有不带nullif的？我只看到了两个可能的位置： 如果TSC。[LTM_Sales_USD]为零且tqc。[LTM_Qty]不为零，则此分区表达式的底部可能为零：

两个简单但手动的技巧： 选项1：注释掉所有输出字段，然后逐个取消注释并运行查询，直到出现错误。您应该能够找到导致错误的字段或表达式，但它可能不是唯一的字段或表达式 选项2：将结果集限制在前10名、前1000名等，直到触发错误。然后减少记录数，直到错误消失。最好包含所有联接表的ID，这样您就可以精确定位所涉及的记录。也可以按ID排序。如果错误发生在ID 999之后，则您知道下一个ID 1000或任何可能是问题开始的地方 我将从选项1开始。确定有问题的表达式后，分别输出各个字段/值。一切都应该变得清晰 例如，如果您注意到此表达式正在崩溃：

TLPC.Standard_List,
FX.Exchange_Rate,
CPPG.[Discount Percentage],
TSC.[LTM_Sales_USD]
再看看这些值，特别是tqc。[LTM\U Qty]。当你得到一个被零除的错误时，它不会告诉你行。我建议从没有NULLIF{divisior}，0的除法开始，因为有几个除法。另外，为什么你的别名一直在最右边，没有人可以看到它们而不滚动？请查看页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处的页边空白处。分母的CASE语句可能会产生这样的错误。哇，你真的希望有人能通过这个怪物式的表达吗把它分成更小、更易消化的部分怎么样？附加说明：。例如，事实、数量、依赖、列表、价格、所有国家都没有一个b，那么为什么它的别名是b呢？而且，这是一个很长的对象名。
