Oracle PL/SQL Programming

This Oracel PL/SQL training course will teach you to increase the productivity, performance, scalability, portability, and security of your Oracle database. With this training, you will learn how to execute PL/SQL programs in Oracle, build stored procedures, design and execute modular applications, and increase the efficiency of data movement — essential skills for any Oracle developer.


Delegates will learn how to
•Develop efficient PL/SQL programs to access Oracle databases
•Create stored procedures and functions for reuse and maintenance
•Design modular applications using packages
•Manage data retrieval for front-end applications
•Invoke native dynamic SQL to develop high-level abstract code
