Oracle Database 12c: SQL II - Intermediate
Oracle Training Overview

This course builds upon the prerequisite introductory volume from the Oracle Database 12c: SQL Expert Series and considers intermediate-level SQL topics such as writing database queries using the SQL-99 syntax and exploiting the power of built-in functions that extend the capabilities of SQL.

You will learn how to complete of an application schema definition by creating database objects such as relational views, sequences, synonyms, indexes and others to compliment the table definitions. The crucial topic of data integrity and how this is protected using declarative constraints is covered.

With this course we will also leave the idyllic realm of the learning environment and begin to explore such practical real-world considerations as database object security and database performance.


Oracle Training Audience

The audience for this course is all Oracle professionals, both business and systems professionals. Among the specific groups for whom this course will be helpful are:
  • Business and non-IT professionals
  • Application designers and developers
  • Business Intelligence (BI) analysts and consumers
  • Database administrators
  • Web server administrators
Oracle Training Certification

This course considers subjects applicable to certification as an Oracle Database Certified SQL Expert. The topics considered are included within "Exam 1Z0-047: Oracle Database: SQL Certified Expert". One must also complete the related volumes from the Oracle Database 12c: SQL Expert Series entitled Oracle Database 12c: SQL I Introduction and Oracle Database 12c: SQL III - Advanced to prepare for this certification.


Oracle Training Objectives

This course demonstrates how one can build intermediate-level and even advanced queries using the SQL-99 join syntax, along with other advanced query topics. It also considers both ANSI/ISO and native Oracle SQL built-in functions and the tremendous power that functions offer to SQL operations. It is difficult for one to use SQL within a production environment without liberal use of the built-in functions. Among many other tasks, the built-in functions allow one to move beyond the use of primitive date data types and values to include timestamps, time zones and to address other realistic date and time challenges. Finally attention is given to how one completes an application schema by creating database objects to compliment table definitions. One cannot implement a production database application simply with table and column definitions but needs to create and manage views, indexes, constraints and other object types.
