Oracle 12c - PL/SQL Fundamentals

5 Days

30 CPD hours

This course is intended for individuals who are Application designers and database developers, database administrators and web server administrators.

Upon successful completion of this course, students will be able to work with Oracle database programming using the PL/SQL programming language. They will learn the syntax, structure and features of the language.

In this course, students will learn the foundation for the programming series and the use of database-resident stored program units for Oracle 12c.
