Oracle SQL Advanced
Your pathway to expert-level Oracle SQL
Gain advanced Oracle SQL capabilities through practical, instructor-led training. Across two comprehensive days, you’ll work with analytic queries, flashback tools, regular expressions, and large dataset techniques. This course also aligns with recognised Oracle certification pathways, adding value to your professional credentials.
Learning objectives
- Write efficient and advanced subqueries
- Retrieve and manage hierarchical data
- Apply advanced analytic and ranking functions
- Merge, insert, and manage large datasets
- Clean and validate data using regular expressions
- Utilise Oracle flashback features for data recovery
- Control and secure access to database objects
- Query and manage external tables and files
- Work effectively with timestamps, time zones, and intervals
What you’ll learn
Over two days, you’ll gain hands-on experience with advanced Oracle SQL functions, learning how to optimise data retrieval while using specialised features such as flashback and regular expressions. These skills help you manage complex datasets efficiently and solve challenging database problems with confidence.
Advanced subqueries and data retrieval
Enhance your query skills with advanced subquery techniques, including correlated subqueries, in-line views, and multi-column approaches. Learn to apply the WITH clause and execute complex updates directly from queries. These capabilities can enable you to retrieve and manipulate data with greater precision, meeting the demands of sophisticated reporting and data analysis across large Oracle database environments.
Hierarchical and analytic queries
Work confidently with hierarchical data using START WITH and CONNECT BY clauses, and sequence output effectively. Develop analytic queries using ranking functions, NTILE, LISTAGG, and aggregate functions to deliver deeper insights. By combining these techniques, you can uncover trends, patterns, and relationships in your data that are essential for advanced analysis and informed decision-making in complex projects.
Managing large datasets
Learn to handle high-volume data with ease through multi-table inserts, conditional and unconditional inserts, and merge operations. Gain the ability to consolidate data from different sources efficiently and accurately. These techniques help streamline data integration, support faster processing, and ensure consistency in business-critical environments where speed, scalability, and reliability are essential.
What’s included
- Two full days of live virtual classroom training
- Tuition from highly experienced Oracle instructors
- Access to digital course materials and guided practical exercises
- A certificate of completion to validate your learning

FAQs
This advanced Oracle SQL course teaches practical techniques for complex queries, data recovery, and pattern matching. Ideal for experienced users seeking faster workflows and preparation for Oracle certification.
Does the Oracle SQL Advanced course help with Oracle certification exams?
Yes. When taken alongside the Oracle SQL course, this training is an excellent step towards the Oracle Database SQL Fundamentals 1Z0-071 exam. Combined with the Oracle SQL and Oracle Database 19c Administration courses, it also supports preparation for the Oracle Database Administration I 1Z0-082 exam.
Is this Oracle SQL Advanced course suitable for beginners?
No, this course is designed for learners who already have a solid understanding of Oracle SQL. If you’re new to SQL or need to refresh the basics, we recommend completing the Oracle SQL course first. This ensures you have the foundational skills needed to get the most value from the advanced topics covered.
How can I use subqueries and data merging in Oracle SQL?
In this Oracle SQL Advanced course, you’ll master correlated subqueries, in-line views, and the WITH clause to simplify complex logic and improve query clarity. You’ll also learn Oracle’s MERGE statement for combining, updating, and synchronising large datasets - essential for bulk operations, data integration projects, and enterprise-scale database management.
When should I use regular expressions and external tables in Oracle SQL?
Regular expressions are invaluable when you need to quickly identify, clean, or transform inconsistent data, such as validating formats or extracting key details without manual intervention. External tables allow you to query data stored outside the database, avoiding time-consuming imports. In this Oracle SQL Advanced course, you’ll learn how to apply both techniques to streamline workflows, reduce errors, and handle large-scale data more efficiently.
What our customers say
"John is an exceptional teacher. I first completed the SQL course with him four years ago, followed by PL/SQL two years later, and most recently, the Advanced SQL training. Each course has significantly contributed to my career development. John’s teaching style, clarity, and support have made a lasting impact on my learning journey.”
Mihai – Oracle SQL Advanced Learner
"The course was particularly good and certainly took my SQL to another level. A lot of extremely useful stuff beyond programming. And it certainly gave ideas of what is possible. The instructor was particularly good and very knowledgeable. Anything he didn't know, he would investigate and provide the explanation. That is not my first class with him and one of the reasons, I book with StayAhead.”
