问题描述
我的数据集和查询对话框中有非常简单的选择查询。当我运行此查询时，我得到数据库中的 2倍数据字段！我的报告书有比报告本身更多的页面，我想这是因为冗余数据。即使没有 distinct ，也可以在Jaspersoft 6数据字段中提供3个数据字段！
I have very simple select query in my dataset and Query dialog. When I run this query I get 2 times more data fields as there are in the database! And my report book has more pages than the report itself, which I guess happens because of the redundant data. The same query delivers 3 data fields even without distinct and in Jaspersoft 6 data fields!
select distinct *
from KennzahlReferenz2015_QIBericht, Images
where LB_ID = 62
and KN_OffiziellGruppe =3
and IMG_ID = 1

推荐答案
问题不在于驱动程序或源代码。当我添加报告书时会发生这种情况。然后波书要求数据源和查询。当我在那里写一个查询时，jasper将这些结果添加到主报告中。
The problem is not because of the driver or source code. It happens when I add a report books. Then the wave book asks for a data source and query. When I write a query there, jasper adds those results to the ones from main report.
这篇关于jasper中的重复数据的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
