This course introduces students to PL/SQL and helps them understand the benefits of this powerful programming language. Students learn to create PL/SQL blocks of application code that can be shared by multiple forms, reports, and data management applications. Students learn to create anonymous PL/SQL blocks as well as stored procedures and functions. 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, triggers, declaring identifiers and trapping exceptions.

Students are introduced to the utilization of some of the Oracle-supplied packages.This course is a combination of Oracle Database 11g: PL/SQL Fundamentals and Oracle Database 11g: Develop PL/SQL Program Units courses.Students use Oracle SQL Developer to develop these program units. SQL*Plus and JDeveloper are introduced as optional tools.

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.

This is appropriate for a 10g audience too. There are few minor changes between 10g and 11g features.

Learn to:

Conditionally control code flow (loops, control structures)
Design and use PL/SQL packages to group and contain related constructs.
Create triggers to solve business challenges.
Use some of the Oracle supplied PL/SQL packages to generate screen output and file output.
Create anonymous PL/SQL blocks of code.
Declare PL/SQL Variables
Application Developers
Database Administrators
Forms Developer
PL/SQL Developer
Portal Developer
System Analysts
Technical Consultant
