Oracle Database 11g: Develop PL/SQL Program Units

This course is no longer available. New course is OR107 Oracle Database 11g: Program with PL/SQL

This course is designed for developers with basic PL/SQL and SQL language skills. Students learn to develop, execute, and manage PL\SQL stored program units such as procedures, functions, packages, and database triggers. Students also learn to manage, PL/SQL subprograms and triggers. Students are introduced to the utilization of some of the Oracle-supplied packages.

Additionally students learn to use Dynamic SQL, understand design considerations when coding using PL/SQL, understand and influence the PL/SQL compiler and manage dependencies.

In this course, students use Oracle SQL Developer as the main tool and SQL*Plus is introduced as an optional tool.

This course counts towards the Hands-on course requirement for the Oracle Database 11g Administrator Certification. Only instructor-led inclass or instructor-led online formats of this course will meet the Certification Hands-on Requirement. Self Study CD-Rom and Knowledge Center courses DO NOT meet the Hands-on Requirement.

Learn to:

Create, and execute stored procedures and functions.
Design and use PL/SQL packages
Create overloaded package subprograms for more flexibility.
Utilize Oracle-Supplied Packages in Application Development
Create triggers to solve business challenges.
Build and execute SQL statements dynamically.

Målgrupp:
