Oracle Program with PL/SQL Course Overview The Oracle Program with PL/SQL training course introduces the delegate to Oracle's PL/SQL programming language and provides practical experience in writing stand-alone programs,developing database triggers and implementing stored functions,procedures and packages. It also introduces some of the Oracle-supplied packages. Similarly,the course is targeted to closely follow the official Oracle Database curriculum for certification. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered. Versions supported 12cR2,18c and 19c.
COURSE OBJECTIVE:
Course Objectives To provide the skills needed to develop,write and maintain PL/SQL scripts,triggers,stored program units and packages.
TARGET AUDIENCE:
Who will the Course Benefit? Oracle database administrators,software development personnel and database support staff who need to write PL/SQL scripts and implement or maintain database triggers,program units and packages.
COURSE PREREQUISITES:
Requirements A working knowledge of Oracle SQL or SQL Developer is required along with practical experience in writing SQL statements. This knowledge can be obtained by attendance on the pre-requisite Oracle SQL course. Some previous programming experience will also prove advantageous.
