Division by Zero ETL Formula
Hi everyone,
Can someone help me with this issue... trying to input a formula in Magic ETL and I got a division by zero error. How can I rectify it? I know in some cases the divisor in my calculation will be 0 but that is okay.
Case when `ServiceName` like '%Manual_Only%' then (`InCallMin`) / ((`ReadyMin`+`InCallMin`+`NotReadyMin`+`WrapUpMin`) (`LunchMin`+`BreakTimeMin`+`TrainingMin`+`MeetingMin`)) end
Thanks for any assistance

Hi @Shumilex
Looks like an operator is missing between `WrapUpMin`) and (`LunchMin`
What should that operator be? You'll need to utilize your CASE Statement to check for your denominator value being 0 prior to running the calculation with your denominator.
CASE WHEN `ServiceName` like '%Manual_Only%' THEN CASE WHEN ((`ReadyMin`+`InCallMin`+`NotReadyMin`+`WrapUpMin`)(`LunchMin`+`BreakTimeMin`+`TrainingMin`+`MeetingMin`)) = 0 THEN 0 -- Or whatever value you want when the denominator is 0 ELSE (`InCallMin`) / ((`ReadyMin`+`InCallMin`+`NotReadyMin`+`WrapUpMin`)(`LunchMin`+`BreakTimeMin`+`TrainingMin`+`MeetingMin`)) END END

Thank you. I did the below as well, both seem to give the same results:
case
when `ServiceName` like '%Manual_Only%' then (`InCallMin`)/ NULLIF(((`ReadyMin`+`InCallMin`+`NotReadyMin`+`WrapUpMin`) -(`LunchMin`+`BreakTimeMin`+`TrainingMin`+`MeetingMin`)),0)
End
