| 摘 要： | PowerBuilder中单数据窗口只能更新一个表,目前常用的解决方法是编写函数实现基于单数据窗口的两表更新,当表的数目增加时又需要重新编程或重复调用函数.为克服该局限性,对其进行了改进,通过建立全局函数实现单数据窗口的多表更新,提高了代码的可重用性和可维护性,通过向函数传递不同的参数,使程序不必受制于数据库表的个数和名称,体现其通用性,从而使PowerBuilder应用程序的报表更新技术更完善,更灵活.

| Abstract: | PowerBuilder can only update single table in single DataWindow.Now its users often program a function to update two tables of single DataWindow.But with the increasing of tables users need program or call it again and again.To(overcome) this limitation this article modifies the method.Through creating a global function,we accomplish updating multi-(tables).Through passing different parameters to the function,the application will not be limited by the amount or the name of the database tables,so it is universal.It improves the re-use and maintainability of the code and makes the technology of updating reports in PowerBuilder more perfect. |
