Oracle PL-SQL

Learn how to declare, open and manage REF CURSORs (cursor variables) to pass query results dynamically between PL/SQL programme units. You’ll cover cursor lifecycle control, using cursor variables as parameters and applying best practices, helping you to write flexible, modular PL/SQL code that adapts to dynamic data structures and changing application requirements. 

During this course, you’ll explore Oracle database triggers, including DML, DDL, system event and compound triggers. You’ll learn how to automate actions in response to events such as inserts, updates and deletes, while managing permissions and avoiding common errors. You’ll also gain the skills to write reliable triggers that enforce business rules and maintain data accuracy. 

Discover how to build PL/SQL procedures and functions that form the backbone of reusable, efficient code. You’ll cover parameter handling, local subprogrammes, invoking techniques and the differences between invoker’s and definer’s rights. The course also shows you how to use functions safely in SQL, manage autonomous transactions and apply best practices for robust, secure logic. 

Gain confidence in managing runtime issues by learning how to handle exceptions and errors within PL/SQL code with our course. This not only reduces debugging time but also helps you deliver more reliable Oracle applications that can recover gracefully and keep critical systems running smoothly.
