Oracle SQL - Full Course - 2025

Ten days from basics to tuning

This full course is organised as ten numbered days. It starts with the types of SQL statements, DDL, DML, DRL, TCL and DCL, then builds through constraints, single-row functions and joins. The middle days cover aggregate functions, subqueries, set operations and analytical functions, followed by views, indexes, sequences and synonyms. The final days turn to performance tuning and scenario-based interview questions.

Who it suits

Beginners who want a clear progression into Oracle SQL will find the day numbering makes the course straightforward to follow in order. The closing scenario day suits viewers preparing for interviews once the core material is in place.

Takeaways

• Performance tuning gets its own day rather than a passing mention.
• Views and materialized views are split into their own topic.
• The series ends with practice questions in interview form.
