What you’ll learn

Whether you're starting from scratch or brushing up on the fundamentals, this ILX course gives you the essential SQL skills to work confidently with Oracle databases. Learn how to write queries, manipulate data, and manage objects in a practical, hands-on setting.

Designing and running precise queries

Learn how to create highly targeted queries to answer specific business questions. You’ll explore multiple filtering techniques, build custom result sets, and apply logical operators to refine your searches. Practical exercises include combining arithmetic expressions with data retrieval, formatting output for reports, and applying aggregate calculations to generate meaningful insights.

Combining data from multiple sources

Master the skills to bring together information from different tables, even across complex database schemas. You’ll practise multiple join types, experiment with set operators to merge or compare results, and use subqueries to uncover patterns hidden in your data. Real-world scenarios will demonstrate how these techniques power everything from financial reconciliations to customer analytics.

Transforming and analysing information

Go beyond simply retrieving data by learning to reshape and interpret it. You’ll work with Oracle’s conversion functions, apply conditional expressions, and use built-in analytics to rank, segment, and summarise records. You’ll also discover grouping enhancements and multi-level summaries that help present data in ways decision-makers can instantly understand.

Structuring, securing and maintaining databases

Develop the confidence to build and adapt database structures that meet evolving business needs. You’ll create and alter tables, implement constraints to protect data integrity, and design indexes to boost performance. The course also covers managing sequences for automated numbering, securing access through roles and privileges, and using flashback features for data recovery.

FAQs

This ILX Oracle SQL Fundamentals course is a practical experience designed to give you complete confidence working with Oracle databases. From retrieving and updating data to managing database structures, you’ll work effectively with Oracle SQL in professional environments.

Can I use what I learn here with other databases, like MySQL or SQL Server?

Yes, absolutely. While this course uses Oracle, most of the SQL you’ll write is standard and works similarly across platforms like PostgreSQL, MySQL, SQL Server, and others. Oracle has a few unique features (like flashback queries and hierarchical syntax), but the core skills you build here will transfer well to most other systems.

Will I learn how to manage user access and database security in Oracle?

Yes. The course includes a dedicated section on access control where you’ll create and manage user accounts, assign system and object privileges, and revoke access when needed. You’ll learn how to protect sensitive data and ensure users can only perform actions relevant to their role.

Does the course cover working with large datasets efficiently?

It does. You’ll explore Oracle SQL techniques for managing and manipulating large volumes of data, including conditional and unconditional inserts, multi-table inserts, and the MERGE statement for updating or inserting rows in one operation. You’ll also learn grouping enhancements and analytic functions that are especially valuable when working with big datasets.

Will I get to practise complex query techniques like hierarchical queries?

Yes. You’ll learn how to write hierarchical queries using Oracle’s key clauses and work with tree-structured data such as organisational charts or product categories. You’ll also discover how to filter, order and sequence hierarchical results for clear reporting.
