In this course, you will receive hands-on instruction in the intermediate and advanced features of Oracle11g PL/SQL procedural language for SQL. You will learn how to control data sharing and locking, debug and use error reporting procedures use Oracle supplied packages, and develop database triggers, stored procedures, and functions for future reuse.
