摘要
在利用PowerBuilder10.5开发数据库应用程序时,大部分的数据报表都可以通过将数据窗口对象设计成Group样式来实现,它除了类似于Excel中的分类汇总功能外,还通过Trailer栏的计算域存放了各个统计项目的汇总值。主要介绍了Group样式明细数据报表的设计、Trailer栏计算域数据的动态获取、基于Trailer栏计算域数据汇总报表的动态生成以及打印模块的设计。
When application programs of database is being explored by using Power Builder10.5, most data report forms can be realized by designing data window object into Group. Besides the function of classifying and summing, it can store the sum of each statistics project in the computational domain in Trailer. This paper mainly introduces how to design the detailed data report forms, how to get data in the computational domain of Trailer in a dynamic way, how to produce the sum data report form in a dynamic way based on the computational domain in Trailer and how to the design the typing module.
