Take your SQL skills to the next level and learn to write queries with PL/SQL in this online SQL training course.
This self-paced SQL training course is perfect for advancing your current SQL skills. While Oracle uses a standard SQL like other major databases, PL/SQL is specific to Oracle. PL/SQL is a procedural language with variables, conditions, loops, subprograms, stored procedures, and functions.
