Course Overview
This course introduces students to PL/SQL and helps them understand the benefits of this powerful programming language. In the class, students learn to create PL/SQL blocks of application code that can be shared by multiple forms, reports, and data management applications.

What you will learn
Students learn to create anonymous PL/SQL blocks, stored procedures, and functions. They learn about declaring variables and trapping exceptions. Students will also learn to develop stored procedures, functions, packages and database triggers. Students will learn to manage PL/SQL program units manage dependencies, manipulate large objects, and use some of the Oracle-supplied packages. Students use iSQL*Plus to develop these program units. Demonstrations and hands-on practice reinforce the fundamental concepts. This is one of the three exams required to achieve the OCP Developer Certification, and one of the three exams required to achieve the OCP Developer Certification.

Audience
