摘　　要：　讨论了PowerBuilder与数据库的连接方法,并针对如何实现PowerBuilder参数化连接数据库的问题,提出了实现技术.利用PowerBuilder提供的RegistrySet()函数来对操作系统注册表进行读写,达到ODBC接口与数据库的参数化连接;利用PowerBuilder中的ProfileString()函数实现专用接口与数据库的参数化连接.突破了PowerBuilder手工连接数据库的局限,解决了以往连接数据库工作量大、扩展性不好的问题,使PowerBuilder连接数据库的功能更加完善.This article discusses the means to connect the application with the database in PowerBuilder.it also provides implementation technology to the problems in parametric connection of database in PowerBuilder. Using RegistrySet() function in PowerBuilder reads or writes windows register table realization ODBC interface parametric connection of database in PowerBuilder. Using ProfileString() function realizes special database interface parametric connection of database. It breaks the confine that uses handwork connection of database, raveal the problem in a lot of designing program work and infirmly extend anciently. Using the means in this article can make technology of connection of database in PowerBuilder more perfect. 
