This Oracle Database: PL/SQL Fundamentals training introduces you to PL/SQL and explains the benefits of this programming language. You'll learn how to create PL/SQL blocks of application code that can be shared by multiple forms, reports and data management applications. Learn To:Conditionally control code flow (loops, control structures).Use explicit cursors.Handle runtime errors.Describe stored procedures and functions.Work with composite data types.Declare PL/SQL variables.Create anonymous PL/SQL blocks, stored procedures and functions.Declare identifiers and trap exceptions.Benefits to YouEnrolling in this course will teach you how to extend the functionality of the SQL language with PL/SQL language to write application code. Your organization can then realize the full benefit of utilizing Oracle best practices.Participate in Hands-On ExercisesDemonstrations and hands-on exercises reinforce the fundamental concepts you'll learn in this course, which is designed for a 10g and 11g audience (there are minor changes between 10g and 11g features). You'll use Oracle SQL Developer to develop these program units. SQL*Plus and JDeveloper are available as optional tools.
