iReport: Passing parameters from a main report query to a dataset query for a table or list

阅读更多关于 iReport: Passing parameters from a main report query to a dataset query for a table or list

I understand how to pass parameters from a main report to a subreport, since there's a specific field for this in the subreport object. However, I'd like to do the same thing with a table or list object as a consumer (rather than a subreport). Is it possible? For example, say I have a parameter of 'customerID' that I can populate with a main report query, but I can't seem to pass this parameter to the table's dataset's SQL query. I've tried, and continue to try, various combinations of parameters, fields, and variables, but to no avail. Does this sort of thing require a subreport

JasperReports,Jasper .[dʒæspə]碧玉 16.1　JasperReports简介 JasperReport是一个强大、灵活的报表生成工具，能够展示丰富的页面内容，并将之转换成Excel、PDF、HTML或者XML格式。这个工具是开源的，完全使用java编写。 JasperReport由一份XML格式的报表设计文件开始，经过编译、填充、导出或预览，可以产生多种格式的报表文件。除此之外，它还提供了一个iPeport的开发工具，该工具能以所见即所得的方式来开发报表定义文件。使用JasperReports开发报表的核心工作就是编辑一个报表设计文件。这个文件可以使用手工方式编辑，这种方式效率低下，也可以使用iReport。 16.1.1下载和安装JasperReport 到官方站点： http://jasperreports.sourceforge.net 下载（目前站点改为http://jasperforge.org/了，读者注）。下载解压后在dist文件夹内找到它的API文档和JAR包下载其他开源项目 JasperReports框架生成一些格式的文档可能依赖另外一些开源项目，例如生PDF文档依赖于iTest项目；生成Excel文件则依赖POI项目。 16.1.2　JasperReports初探以开发一个静态报表为例。首先把jasperReports
