摘要
实现了一种基于OCI9的Oracle数据库调用接口,用以替代空管系统中现有的基于OCI7.3的数据库调用接口。文章详细描述了数据库调用接口的设计与实现,对OCI版本7.3和版本9进行对比介绍,同时给出接口中网络连接断开的错误处理、单次查询返回多行结果及LOB类型数据操作等关键技术的详细说明,最后通过实验对比两个版本的接口在性能上的差异。
A implement of Oracle database call interface based on OCI9 for the replacement of the existing air traffic control system database called interface based on OC17. 3. The paper describes design and implementation of the database call interface in detail, introduces differences between OCI version 7. 3 and version 9, and gives a detailed description of connection loss error handling, query once to return multi - line results, LOB types of data manipulation, etc. Finally, a set of experiments was given to comparing the two ver- sions of the interface differences in performance.
