Hi everyone!

That's my question....which is better?.

a) Write the sql statement inside a report using iReport for example. Some situations may be not be solved with a unique sql query, and Jasper does not allow multiples queries in a single report.

b) Prepare a class that make some queries and input the reports with parameters with the precalculed values.

Thanks!!!
