Oracle Database: SQL Fundamentals I
Duration: 3 Days
What you will learn
This course introduces participants to the fundamentals of SQL using Oracle Database technology. In this course
participants 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, and create database objects.
The participants also learn to use single row functions to customize output, use conversion functions and conditional
expressions. In addition, the usage of group functions to report aggregated data is also dealt with. Demonstrations and
hands-on practice reinforce the fundamental concepts.
In this course, participants use Oracle SQL Developer as the main tool and SQL*Plus is available as an optional tool.
This is appropriate for a 10g and 11g audience. There are minor changes between 10g and 11g features in SQL.
