SQL FUNDAMENTALS

Oracle Database: SQL Fundamentals I
Duration: 20 Hrs

What you will learn
This SQL Fundamentals training teaches you how to write SQL queries to access data stored in an Oracle Database schema. Learn to manipulate data and use various types of functions for customizing data output.

This course introduces you to the fundamentals of SQL using Oracle Database technology. Learn the concepts of relational databases and the powerful SQL programming language. You will learn essential SQL skills that allow developers to write queries against single and multiple tables, manipulate data in tables, and create database objects. Participants learn to use single row functions to customize output, use conversion functions and conditional expressions. In addition, the usage of group functions to report aggregated data is also dealt with. Demonstrations and hands-on practice reinforce the fundamental concepts.
This SQL Fundamentals training teaches you how to write SQL queries to access data stored in an Oracle Database schema. Learn to manipulate data and use various types of functions for customizing data output.Use Oracle SQL Learn To:

  • Retrieve row and column data from tables with the SELECT statement.
  • Create reports of sorted data.
  • Display data from multiple tables.
  • Use DML statements to manage data.
  • Use DDL statements to manage database objects.
  • Create reports of restricted data.

Benefits To You:
Gain expertise in relational database data management as you learn how to effectively use SQL commands against your business data. 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. This is appropriate for a 10g and 11g audience. There are minor changes between 10g and 11g features in SQL.
