In this course you will learn the main structures of PLSQL: the blocks, the loops, exceptions, variables. And you will see that PLSQL (or also written as PL/SQL) is used in many, many Oracle products. You can use it to split very complex queries to more manageable pieces, to improve performance and for advanced security.

This course is one of the more fundamental courses (together with SQL and Stored Procedures) for many Oracle courses.
