我在SELECT语句的起始位置遇到了除以零的错误，但不确定错误的确切位置。我将NULLIF（，0）放在有除法命令的位置，但是仍然返回除零错误。有没有一种方法可以准确指出错误的触发位置？

答案 0 :(得分：1)
我只看到两个可能的地方：
如果TSC.[LTM_Sales_USD]为零而tqc.[LTM_Qty]不为零，则该除法表达式的底部可能为零：
1- CASE WHEN TQC.[LTM_Qty] IS NULL OR TQC.[LTM_Qty]=0
THEN sc2020.[Standard_Cost]*FX.Exchange_Rate
ELSE (TSC.[LTM_Cost_USD])/NULLIF(tqc.[LTM_Qty],0) END
/CASE WHEN TQC.[LTM_Qty] IS NULL OR TQC.[LTM_Qty]=0
THEN TLPC.Standard_List*FX.Exchange_Rate*(1-CPPG.[Discount Percentage])
ELSE (TSC.[LTM_Sales_USD])/NULLIF(tqc.[LTM_Qty],0) END
同样，如果WHEN为零（或者如果我正在读取的顺序为-1，则ELSE和TLPC.[Standard_List]+TLPC.[PY_Standard_List]的底部都可以为零。操作错误）：
,CASE WHEN ( (TLPC.[Standard_List]-TLPC.[PY_Standard_List])
/
(TLPC.[Standard_List]+TLPC.[PY_Standard_List]) + 1
)/2 IS NULL
THEN 0.5
ELSE ((TLPC.[Standard_List]-TLPC.[PY_Standard_List])
/
(TLPC.[Standard_List]+TLPC.[PY_Standard_List]) + 1)/2 END
答案 1 :(得分：0)
我发现可能会被零除的行：
"Margin_at_ASP_as_%_of_ASP"
.../CASE WHEN TQC.[LTM_Qty] IS NULL OR TQC.[LTM_Qty]=0
THEN TLPC.Standard_List*FX.Exchange_Rate*(1-CPPG.[Discount Percentage])
ELSE (TSC.[LTM_Sales_USD])/NULLIF(tqc.[LTM_Qty],0) END
THEN或ELSE都可能为0。
"List Price % Change (scaled)"
CASE WHEN ((TLPC.[Standard_List]-TLPC.[PY_Standard_List])
/
(TLPC.[Standard_List]+TLPC.[PY_Standard_List]) + 1)/2 IS NULL
THEN 0.5
ELSE ((TLPC.[Standard_List]-TLPC.[PY_Standard_List])
/
(TLPC.[Standard_List]+TLPC.[PY_Standard_List]) + 1)/2 END
WHEN和ELSE都可能为0。
旁注–我是否只是为您搜索每个/并找到所有没有nullif的注释？
答案 2 :(得分：0)
两个简单但手动的技巧：
选项1：注释掉所有输出字段，然后逐个取消注释它们并运行查询直到出现错误。您应该能够找出导致错误的字段或表达式，但它可能不是唯一的。
选项2：将结果集限制为TOP 10，TOP 1000等，直到触发错误为止。然后减少记录数，直到错误消失。最好包括所有联接表的ID，以便您可以查明所涉及的记录。并按ID排序。如果错误是在ID 999之后发生的，那么您可能知道问题的下一个ID（1000或类似的数字）。
我将从选项＃1开始。确定表达式有问题后，请分别输出各个字段/值。一切都应该变得清楚。
例如，如果您注意到此表达式崩溃了：
,CASE WHEN TQC.[LTM_Qty] IS NULL OR TQC.[LTM_Qty]=0
THEN TLPC.Standard_List*FX.Exchange_Rate*(1-CPPG.[Discount Percentage])
ELSE (TSC.[LTM_Sales_USD])/NULLIF(tqc.[LTM_Qty],0) END AS "ASP_USD"
然后输出这些列：
TQC.[LTM_Qty],
TLPC.Standard_List,
FX.Exchange_Rate,
CPPG.[Discount Percentage],
TSC.[LTM_Sales_USD]
然后查看这些值，尤其是tqc.[LTM_Qty]。
