Duration: 24 hours

Description

The course is an introduction to the Oracle® PL/SQL procedural language. The language version used in DBMS 11g is considered in this training.

The course focuses on the basics of the PL/SQL language and its structures, such as anonymous blocks, procedures and functions, as well as on specifics of their operation on the Oracle® 11g R2 database server. The training talks about various types of data (including composite types and collections), control statements, as well as the mechanism of exceptions triggering and exceptions handling in EXCEPTION block. Oracle® SQL Developer is used for developing.
