    About this Course

    Oracle 19c PL/SQL Fundamentals is a three-day, hands-on course that introduces Oracle database programming using the PL/SQL programming language. Throughout the course students will explore the core syntax, structure, and features of the language. This course will also lay the foundation for the entire 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.

    The course also explores applying the newly learned skills to developing database applications. Participants will learn how to use database-resident stored program units such as procedures, functions, packages and database triggers. Students will also learn about the latest features in Oracle 19c.

    NOTE: This training is NOT Official Oracle University training. This is independent, adjustable content that aligns with current topics, skills and tools that participants need to excel in these areas.

    Audience Profile

    This course is geared for anyone needing to interface with an Oracle database such as end users, business analysts, application developers and database administrators / DBAs.

    At Course Completion

    Working within in a hands-on learning environment, guided by our expert team, attendees will develop a practical approach to Oracle Database Technology. Throughout the course, participants will explore:

    • Using PL/SQL programming language for database applications and development
    • Incorporating PL/SQL modules within the application architecture from the initial design and planning phase
    • The essentials of building executable PL/SQL program units
    • Each of the major segments of a working program and how these interact with each other during program execution,
