PL/SQL(程序语言/结构化查询语言)是 Oracle Corporation 对 SQL 的专有程序扩展。它是一种强大的程式设计语言,旨在与 Oracle Database 无缝协作,使用户能够创建复杂的资料库驱动应用程式。
此讲师指导的现场培训(在线或现场)面向希望学习 PL/SQL 以自动化资料库任务、实施业务逻辑和开发强大的资料库应用程式的初级开发人员和资料库管理员。
在本次培训结束时,参与者将能够:
- 开发高效的 PL/SQL 程式来自动化资料库操作并有效地集成SQL命令。
- 为模组化和可扩展的应用程式创建可重用的程式单元,包括过程、函数、包和触发器。
- 实施高级数据结构(如关联数位)并使用游标管理查询结果。
- 使用加密、混淆和条件编译技术稳健地处理错误并保护代码。
- 在实际场景中应用 PL/SQL,利用内置软体包进行文件处理、电子邮件自动化和其他高级功能。
课程形式
- 互动讲座和讨论。
- 大量的练习和练习。
- 在即时实验室环境中动手实施。
