Course Description:

This Oracle Database: Introduction to SQL training helps you write subqueries, combine multiple queries into a single query using SET operators and report aggregated data using group functions. Learn this and more through hands-on exercises.

Learn To:

    Understand the basic concepts of relational databases ensure refined code by developers.
    Create reports of sorted and restricted data.
    Run data manipulation statements (DML).
    Control database access to specific objects.
    Manage schema objects.
    Manage objects with data dictionary views.
    Retrieve row and column data from tables.
    Control privileges at the object and system level.
    Create indexes and constraints; alter existing schema objects.
    Create and query external tables.

Benefits to You:

Ensure fast, reliable, secure and easy to manage performance. Optimize database workloads, lower IT costs and deliver a higher quality of service by enabling consolidation onto database clouds.

Learn Advanced Features of SQL:

This course will help you understand the advanced features of SQL. Learning these features will help you query and manipulate data within the database, use the dictionary views to retrieve metadata and create reports about their schema objects. Some of the date-time functions available in the Oracle Database are also covered.

Use Development Tools:

The main development tool used in this training is Oracle SQL Developer. SQL*Plus is available as an optional development tool. This is appropriate for a 10g and 11g audience.

Please note: This course is a combination of Oracle Database: SQL Workshop I and Oracle Database: SQL Workshop II courses.

Pre-requisites:

    Data processing
    Familiarity with data processing concepts and techniques

Performance Based Objectives:

At the end of this course you will be able to:

  • Identify the major structural components of the Oracle Database 12c
  • Create reports of aggregated data
  • Write SELECT statements that include queries
  • Retrieve row and column data from tables
  • Run data manipulation statements (DML) in Oracle Database 12c
  • Create tables to store data
  • Utilize views to display data
  • Control database access to specific objects
  • Manage schema objects
  • Display data from multiple tables using the ANSI SQL 99 JOIN syntax
  • Manage objects with data dictionary views
  • Write multiple-column sub-queries
  • Employ SQL functions to retrieve customized data
  • Use scalar and correlated sub-queries
  • Create reports of sorted and restricted data
