Description

This course is designed to deliver the fundamentals of SQL and PL/SQL along with the benefits of the programming languages using Oracle Database technology. In this course participants learn the concepts of relational databases. Additionally the participants are provided with the essential SQL skills that allow them to write queries against single and multiple tables, manipulate data in tables, and create database objects. The usage of single row functions to customize output, how to invoke conversion functions and conditional expressions are covered. The use of group functions to report aggregated data is also included. Additionally students learn to create PL/SQL blocks of application code that can be shared by multiple forms, reports, and data management applications. Participants also learn to create anonymous PL/SQL blocks, stored procedures and functions. Participants get to learn about declaring identifiers and trapping exceptions. Demonstrations and hands-on practice reinforce the fundamental concepts.
