关于Oracle数据库动态SQL数据获取应用方法的研究与实践

Reaserch and Practice on Dynamic SQL Technology in Oracle Database

在Oracle数据库中,为了开发高效率的数据库应用程序,必须灵活的使用动态SQL技术来实现数据获取,为处理任何SQL语句,必须应用最高级的动态SQL方法四,该文研究了如何利用动态SQL方法四处理选择列表项和宿主变量个数在程序编写时都不确定的SQL语句,并在此基础上加以实践。

In Oracle database,in order to develop the high efficiency of the database application procedure,we must neatly use dynamic SQL technology to realize the data acquisition.To process any SQL sentence,we must apply the most senior dynamic SQL method four.This article discusses how to use the dynamic SQL method four processing the choices tabulated item and the host variable integers are indefinite when programming the SQL sentence,and performed to practice.
