Build powerful database programming skills with Oracle PL/SQL Training, a practical course designed for developers, database administrators, SQL professionals, and IT specialists who want to create efficient, reusable, and maintainable programs within Oracle Database.
Duration 5 days – 35 hrs
Overview
This Oracle PL/SQL Training provides a comprehensive, hands-on introduction to Oracle’s Procedural Language extension for SQL (PL/SQL), designed to help participants develop reliable, efficient, and maintainable database applications. Over 5 days (35 hours), learners will progress from SQL fundamentals and PL/SQL programming concepts to developing reusable database program units and implementing practical database solutions.
Participants will learn how to create and execute PL/SQL blocks, work with variables and control structures, process single and multiple rows using cursors, and handle runtime errors through effective exception-handling techniques. The course then progresses to developing stored procedures, functions, packages, and triggers, enabling learners to organize business logic and automate database operations within Oracle Database.
Through instructor-led demonstrations, hands-on exercises, and practical development scenarios, participants will apply PL/SQL to common business requirements such as data validation, data processing, reporting, database automation, and transaction management. The training also introduces debugging techniques, bulk processing, performance optimization, secure coding practices, and PL/SQL development standards.
By the end of the course, learners will have practical experience designing and developing reusable PL/SQL programs and will complete a capstone project that combines procedures, functions, and packages into a functional database solution. This provides a strong foundation for applying Oracle PL/SQL in enterprise applications and progressing toward advanced Oracle database development.
