przemekwi444 Posted March 31, 2017 Share Posted March 31, 2017 Hello, I am facing a following problem:performance is very important in my application. Reports contains 5 subreports, each of them uses the same sql query and JDBC.Is it possible to query database only once instead of six times (one from parent master + 5 subreports)?
