Fundamentos de SQL e PL/SQL

SQL/PL10g - Oracle 10g: Fundamentos de SQL e PL/SQL

Descrição:

Learn the SQL and PL/SQL fundamentals using SQL Developer on Linux. This course offers students an introduction to Oracle Database 10g database technology. In this class students learn the concepts of relational databases and the powerful SQL programming language. This course provides the essential SQL skills that allow developers to write queries against single and multiple tables, manipulate data in tables, create database objects, and query meta data. This course also introduces students to PL/SQL and helps them understand the benefits of this powerful programming language. In the class, 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 and are introduced to stored procedures and functions. They learn about declaring variables, trapping exceptions and they also learn to declare and control cursors.
