一种基于PB的带参数数据窗口对象的灵活查询方法研究

On the Methods of Agile Inquires Based on the PB with Parameter Data Window Object

PowerBuilder在数据窗口对象中加入参数元素,较大地拓展了数据的应用领域,丰富了其表现形式,操纵使用数据库表的能力愈强。PowerBuilder可以实现更简化的编码和更短的开发周期,从而为用户提供更高的生产力,在科技情报工作检索中有其广泛用途。

PowerBuilder joins the parameter element in the data window object, which can greatly extend the application fields of data, enrich its forms, and have stronger manipulation ability to use a database table. Power- Builder can realize more simplified code and more short development cycle, so as to provide users with higher pro- ductivity. It＇s widely used in science and technology intelligence retrieval.
