What you will learn
This Oracle Database: Develop PL/SQL Program Units course is designed for developers with basic PL/SQL and SQL language skills. You will learn to develop, execute and manage PL/SQL stored program units, which include: procedures, functions, packages and database triggers.
Learn To:
Create, and execute stored procedures and functions.
Design and use PL/SQL packages.
Create overloaded package subprograms for more flexibility.
Utilize Oracle supplied packages in application development.
Create triggers to solve business challenges.
Build and execute SQL statements dynamically.
Manage PL/SQL subprograms and triggers.
Understand and influence the PL/SQL compiler.
Manage dependencies.
Benefits to You
Ensure fast, reliable, secure and easy to manage performance. Optimize database workloads, lower IT costs and deliver a higher quality of service by enabling consolidation onto database clouds.
Learn Dynamic SQL, Design Considerations and More
This course will also teach you how to use Dynamic SQL through instruction, as well as hands-on exercises. Expert
Oracle instructors will also help you understand design considerations when coding using PL/SQL.
Using Oracle SQL Developer
In addition, you’ll use Oracle SQL Developer as the main environment tool to develop these program units. SQL*Plus is introduced as optional tools. Demonstrations and hands-on practice reinforce the fundamental concepts you’ve learned throughout the course.
