(36 horas)
line

Objetivo do Curso

What you will learn: This course starts with an introduction to PL/SQL and proceeds to list the benefits of this powerful programming language. Through hands-on instruction from expert instructors, youll develop stored procedures, functions, packages and more.

Learn To:
Conditionally control code flow (loops, control structures).
Use PL/SQL packages to group and contain related constructs.
Generate triggers to solve business challenges.
Create anonymous PL/SQL blocks, as well as stored procedures and functions.
Use some of the Oracle supplied PL/SQL packages to generate screen output and file output.
Create anonymous PL/SQL blocks, functions and procedures.
Declare PL/SQL variables.
Create PL/SQL blocks of application code that can be shared by multiple forms, reports and data management
applications.
Debug functions and procedures using the SQL Developer Debugger.
Use Dynamic SQL & understand design considerations when coding using PL/SQL.
Understand and influence the PL/SQL compiler and manage dependencies.
Manage PL/SQL subprograms, triggers, declaring identifiers and trapping exceptions.
Course Bundle
This course is the 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.

Audience
Application Developers
Database Administrators
Developer
Forms Developer
PL/SQL Developer
Portal Developer
System Analysts
Technical Consultant

Course Objectives
Create and debug stored procedures and functions
Use conditional compilation to customize the functionality in a PL/SQL application without removing any source code
Design PL/SQL packages to group related constructs
Create overloaded package subprograms for more flexibility
Design PL/SQL anonymous blocks that execute efficiently
Use the Oracle supplied PL/SQL packages to generate screen output, file output and mail output
Write dynamic SQL for more coding flexibility
Describe the features and syntax of PL/SQL
Use PL/SQL programming constructs and conditionally control code flow (loops, control structures, and explicit cursors)
Manage dependencies between PL/SQL subprograms
Handle runtime errors
Create triggers to solve business challenges
Design PL/SQL code for predefined data types, local subprograms, additional pragmas, standardized constants and exceptions

This course works with Oracles digital study material.
