jasper 보고서 하위 보고서가 작동하지 않음 (데이터베이스의 데이터를 표시하지 않음)

Question

하위 보고서가 요약 섹션에 포함 된 주 보고서가 있습니다. 내가 원하는 것은 bill이라는 데이터베이스에 열이없고 열을 표시하려는 것입니다. (즉, where의 where 절에서 billno = 'something'이어야합니다.) 행과 일치하지 않는 행을 표시하고 싶습니다.

현재 주 보고서의 매개 변수를 하위 보고서로 전달 중입니다. 그러나 여전히 그것의 은 작동하지 않습니다.

주 보고서 :

그것은 주 보고서에 널 (null)이 표시됩니다.

Answer 1

나는 해결책을 가지고있다 ... 해결책은 주 보고서에서 전달 된 매개 변수에 하위 보고서 매개 변수를 매핑해야한다는 것이 었습니다.
