Build real-world Oracle SQL skills that enhance your technical knowledge

Our instructor-led course offers a practical exploration into the fundamentals of SQL using Oracle databases. Throughout this focused one-day course, you’ll develop essential knowledge around how to extract and work with data through structured queries to apply straight away in work environments.

Learning objectives

Retrieve data using SQL statements
Use aggregate operations to summarise data
Merge datasets from multiple sources
Create and apply subqueries
Perform operations with SQL set commands
Interpret database architecture principles
Navigate SQL Developer and SQL*Plus
Organise data using filtering and sorting

What you’ll learn

Learn the essential SQL skills that help you work confidently with Oracle databases. Discover how to write queries, join and filter data, use functions and subqueries, and manage tables and views, giving you a strong foundation for ensuring effective reporting, analysis and database operations.

Joining Tables

Explore how to retrieve related information from multiple tables using inner, outer and self joins. You’ll work with table aliases and ANSI join syntax, learning how these techniques reveal relationships across datasets and allow you to construct meaningful queries that reflect real-world database structures.

Subqueries and Set Operators

Develop the ability to write subqueries that simplify complex questions and support advanced filtering. You’ll also learn how to combine and compare results with Oracle set operators, including UNION, INTERSECT and MINUS, gaining practical techniques to extend query power and deliver more insightful database analysis.

Working with SQL Files and Scripts

Understand how to manage SQL files and scripts efficiently. Learn to create, edit and execute scripts within SQL*Plus and SQL Developer, configure sessions with login.sql, and apply scripting methods that improve workflow, enable automation, and ensure queries are consistent across repeated tasks.

Practical Troubleshooting and Output Formatting

Discover how to troubleshoot Oracle SQL effectively by identifying syntax errors, invalid identifiers and common runtime issues. You’ll also explore formatting commands in SQL*Plus, including adjusting line size, page size and column layout, as well as exporting results into readable files for reporting and analysis.
