Oracle® SQL*Plus®

Summary

This course gives an introduction to ORACLE® SQL*Plus® and to SQL, the Structured Query Language used to access a Relational Database. It is based on the ORACLE 8 or 8i relational database but the principles learnt may be applied to databases as diverse as Microsoft SQL Server, Access, DB2 and Mysql.

Prerequisites

The course is suitable for those who have some knowledge of SQL as well as those who are using ORACLE for the first time. Previous experience with an interactive computer system is desirable but not essential.

However, if you have extensive experience of another Relational Database, such as SQL Server, or of Structured Query Language, the follow up course described later may be more appropriate.

Next Steps

ORACLE PL/SQL® would be a natural follow-up to this introductory course. This describes the ORACLE application development environment which allows the writing of programs and stored procedures.

Length

3 days

Format

Instructor-led course, with many practical computer-based exercises.
