Oracle Database: PL/SQL Fundamentals

General Description This course introduces one to Oracle database programming using the PL/SQL programming language. One will learn the syntax, structure and features of the language. This textbook will also lay the foundation for the entire Sideris Oracle PL/SQL programming series, allowing one to progress from introductory topics to advanced application design and programming and finally onto writing complex high-performance applications. _ PL/SQL may be considered as one of the basic skill sets required for any Oracle professional, nearly as important as the SQL language itself. _ This course will also continue on to show those who are now ready to employ the language in the development of database applications. In particular, the focus of this course will be on the use of database-resident stored program units such as procedures, functions, packages and database triggers. New features introduced with the Oracle 12c release of the database are also explained and demonstrated. +++++++++ NOTE ++++++++++ This course content is applicable to versions 11c, 12c, 18c, and 19c.
