Another option would be to "force" the user to enter the formula "C01/C02" in the following format "decode( c2, 0, to_number(null), c1/c2 )" which is not user friendly and forces the How To Avoid Divide By Zero Error In Oracle EXCEPTION WHEN ZERO_DIVIDE THEN return 0; END; Share :TweetShare on TumblrLike this:Like Loading...

Start my free, unlimited access. In ordinary (real number) arithmetic, the expression has no meaning, as there is no number which, multiplied by 0, gives a (a≠0), and so division by zero is undefined. select ( 9 / nullif(0,0)) as result from dual Gottit. this content By automatically letting 0 be the default for nulls you are introducing potentially quite significant bias into your data sets.So, without labouring the point, I recommend that you reconsider this last
You are dividing by 0. Reflection of "Yada yada hi dharmasya..." in Durga Saptashati? Management is interested in the percentage of zeros out of the total number of cases. A full hour of crunching stopped becuase of a 0 on a single row..
That still leaves (a) or (b): why can't a flag be set on that thread telling it to correct the divide by zero, and continue? when I fill this form and submit.
