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.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.
