Comment on Tutorial : Using Variables in JasperReports By MakeItSimple.
Hello,
i want to find the sum of $F{Ac
tivities} in Jaspersoft Studio which are number values,in DB as text. In query by default class type is java.math.BigDecimal.
I created a variable named $V{Tot_activities} with
value class name java.lang.Double
Calculation:SUM
what should be the variable expression?
what should be initial value expression?
I should convert the $F{Activities} from class string to Double to obtain column summary and later back to string is what I understood but dont know how to get it? Any help?
