Course Overview
SQL remains one of the most essential skills for working with data across analytics, engineering, and business intelligence roles. This course helps learners move beyond basic queries to advanced techniques used in professional data analysis and reporting environments.
Across two mentor-led days, participants work through practical scenarios involving complex joins, window functions, subqueries, and query optimisation strategies. The course focuses on writing efficient queries that scale well with large datasets.
Learners will also explore indexing concepts, query execution behaviour, and practical performance improvement techniques. By the end of the course, participants will be able to design advanced SQL queries and optimise database interactions used in analytical and operational systems.
