Training Course Objectives

This 5 day Oracle training course introduces the fundamentals of Oracle's procedural language, PL/SQL, the engine behind the full range of Oracle technology.

The Oracle training course also introduces the syntactic transactional languages controls evolving to cover the full range of PL/SQL programming functionality found within the Oracle 10g RDBMS.

This practical Oracle training course is an essential foundation study course needed for all Oracle 10g RDBMS professionals to maximise their utilisation of Oracle 10g and the productive benefits that can be achieved through the essential deployment of PL/SQL functionality across the business.

Oracle Database 10g also introduces some new PL/SQL language features and some new supplied PL/SQL packages. In this release, there is an increase in runtime performance. Oracle Database 10g brings a new PL/SQL compiler and a newly tuned PL/SQL execution environment. Additionally, the system for the native compilation of PL/SQL has been substantially improved. PL/SQL packages are used to extend the functionality of the Oracle Database when SQL cannot be extended for a required purpose.
