Oracle Database 11g: Program with PL/SQL

Accueil » Formations » Data » Oracle Database 11g: Program with PL/SQL

This course starts with an introduction to PL/SQL and proceeds to list the benefits of this powerful programming language. Participants are made aware of how to create PL/SQL blocks of application code that can be shared by multiple forms, reports, and data management applications. In addition, creation of anonymous PL/SQL blocks as well as stored procedures and functions are covered in this course. Participants enhance their developer skills by learning to develop, execute, and manage PLSQL stored program units such as procedures, functions, packages, and database triggers. Understanding the basic functionality of how to debug functions and procedures using the SQL Developer Debugger gives way to refined lines of code. Participants also learn to manage PL/SQL subprograms, triggers, declaring identifiers, and trapping exceptions. The utilization of some of theOracle-supplied packages is also in the course. Additionally participants learn to use Dynamic SQL, understand design considerations when coding using PL/SQL, understand and influence the PL/SQL compiler, and manage dependencies. This course is a bundle of Oracle Database: PL/SQL Fundamentals and Oracle Database: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 is appropriate for a 10g and 11g audience. There are minor changes between 10g and 11g features.
