TTOR12019

Introductory

3 Days

Course Overview

Oracle 19c PL/SQL Fundamentals is a three-day, hands-on technical 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 the development of 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.

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 workin g program and how these interact with each other during program execution,
•    Important error or exception handling capabilities of the language.
•    How database-resident program units can be used as part of the overall database application architecture
•    Applying these new skills to the development of PL/SQL packages.
•    Advanced database programming capabilities and benefits
•    How database triggers can be used as part of an advanced database application design

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional Oracle, database, scripting, administration, programming, security and other related topics that may be blended with this course for a track that best suits your needs.

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.
