Implementation of Flexible Query of Data in PowerBuilder

为了在 Power Builder中实现灵活的数据查询 ,给出了利用数据窗口控件的函数和动态数据窗口技术来开发动态查询的几种方法 ,使得表名能动态可变。所述方法可以灵活的使用 ,并结合实例对它们进行了分析比较。

In order to achieve the flexible query of data in PowerBuilder,some methods are presented in this paper to develop dynamic query by use of functions of data window control block and dynamic data window technique,which makes the table's name variable in the query sentences.Those methods introduced can be used flexibly,and are compared by examples.
