What you’ll learn
Over three days you’ll build practical Oracle SQL skills step by step, from writing queries and joins to managing tables, views and indexes. You’ll also explore functions, subqueries, transactions and performance techniques, developing the confidence to manage data and structure Oracle databases with efficiency and accuracy.
SQL basics
Begin with the core principles of Oracle SQL, learning how databases are structured and how to use tools like SQL*Plus and SQL Developer effectively. You’ll write queries with SELECT, refine them using WHERE and ORDER BY, and apply aliases and expressions, building a solid foundation for more advanced SQL techniques.
Joins and subqueries
Discover how to work with multiple tables using inner, outer and self joins to bring data together in meaningful ways. You’ll then progress to subqueries, including inline views and correlated subqueries, giving you the skills to answer complex questions and create logic that makes queries more powerful and efficient.
Managing data and structures
Learn how to insert, update and delete rows, then control changes with commits, rollbacks and savepoints to keep data reliable. Explore how to create and modify tables, design views that simplify queries, and apply indexes for faster performance. You’ll also, discover how sequences and synonyms improve efficiency and keep your Oracle SQL environment organised.
Functions and expressions
Explore how to use Oracle SQL functions to transform and analyse your data. You’ll work with numeric, character and date functions, as well as conversion tools like NVL, CASE and DECODE. These techniques allow you to manipulate data effectively, perform calculations, and create flexible queries that reveal deeper business insights.
