Oracle Database: Introduction To SQL

Course details

Understanding the basic concepts of relational databases ensure refined code by developers. This course helps the participants to write subqueries, combine multiple queries into a single query using SET operators and report aggregated data using group functions. Controlling privileges at the object and system level are also dealt with in detail.This course covers creating indexes and constraints, and altering existing schema objects. Additionally, participantslearn how to create and query external tables. In order to query and manipulate data within the database, to use thedictionary views to retrieve metadata and create reports about their schema objects, participants get to understand the advanced features of SQL. Some of the date-time functions available in the Oracle Database are also covered. This course also discusses how to use the regular expression support in SQL. This course is a combination of Oracle Database: SQL Fundamentals I and Oracle Database: SQL Fundamentals II courses. For this course, the main development tool used is Oracle SQL Developer. SQL*Plus is available as an optional development tool. This is appropriate for a 10g and 11g audience. There are few minor changes between 10g and 11g features in SQL.
