mysql - SQL Divide By Zero Error In SELECT Statement -

-

i'm brand new sql , use hand. i'm getting divide 0 error following in select statement:

sum(cast((replace(replace(replace (p.[total sales], '$', ''), '(','-'),  ')','')) money)) - sum(cast((replace(replace(replace (p.[total cost], '$', ''), '(','-'),  ')','')) money)) / sum(cast((replace(replace(replace (p.[total sales], '$', ''), '(','-'),  ')','')) money)) new_bal

i know need use case, i'm not sure of application.

you use nullif in following:

nullif(expression1, 0)

in case be:

sum(cast((replace(replace(replace (p.[total sales], '$', ''), '(','-'),  ')','')) money)) - sum(cast((replace(replace(replace (p.[total cost], '$', ''), '(','-'),  ')','')) money)) / nullif(sum(cast((replace(replace(replace (p.[total sales], '$', ''), '(','-'),  ')','')) money)),0) new_bal
