so now equation become like 1000/0 will hit divide by zero error.Below expression will not give an error.select 1000/17/17/17/17 OR select 1000/(17/17/17.0) -> 1000/0.058823 -> it will work without error.Thanks you Brilliantly simple, just set the variable in the select, which will call the functions as many times as there are records in the select but without the IO overhead. If you have a situation where the ClubTotal is a number and AttTotal is zero, it doesn't make sense to return zero. So in this case, if you have a division by zero, then you should show something like '#INF'. –George Nov 26 '15 at 18:26 add a comment| up vote 0 down
