I am using iReport for developing report
I am using joins for getting data from 4 different tables mysql.
For getting the sum of columns i am using the expression "new Double($F{a}.doubleValue()+$F{b}.doubleValue()+$F{c}.doubleValue())", where a,b,c are in tables a,b,c respectively.
if value of a is null, then the overall sum returned is null regardless of value in b and c column.
For example, row with id 1 is not present in table a, table b, but exists in table c, but still the overall sum returned is null
How to solve this problem?
