Introduction to Oracle 9i: SQL

Additional details

Course ID: OCSQLINT
Duration: 5 days

Profile

This class is applicable to Oracle9i and Oracle8i users. You learn concepts of relational databases, to create database structures and to store, retrieve, and manipulate data. Here you learn to query using Basic SQL Statements, restrict, sort, perform single row functions and group the queried data.

You will write advanced SELECT statements and use advanced techniques such as ROLLUP, CUBE, set operators, and hierarchical retrieval. You will query multiple tables, perform nested queries, implement constraints, use date and time functions, and create sequences and views.

You learn to write SQL and SQL*Plus script files using the iSQL*Plus tool to generate report-like output. Demonstrations and hands-on practice reinforce the fundamental concepts. The SQL Workshop will enhance your learning experience of SQL.

This course counts towards the Hands-on course requirement for the Oracle 9i Database Administrator Certification. Only instructor-led inclass or instructor-led online formats of this course will meet the Certification Hands-on Requirement. Self Study CD-Rom and Knowledge Center courses DO NOT meet the Hands-on Requirement.

Audience:
Database Administrators
System Analysts

Course Objectives:
Describe relational and object relational database concepts
Retrieve, insert, update, and delete data
Use the Single row and Group functions
Retrieve data using additional advanced techniques like using ROLLUP, CUBE, set operators, correlated subqueries and hierarchical queries
Solve problems by using multicolumn subqueries, subqueries in the from clause of a SELECT statement, correlated subqueries, and scalar subqueries
Use the iSQL*Plus environment
Write scripts to generate script files
Generate reports using iSQL*Plus
Create and maintain database objects
Control transactions
Control data/user access
Use the Oracle9i Single row functions
Use GROUPING SETS and the WITH clause
Use the Oracle9i extensions to DML and DDL statements
Apply techniques in real life simulation
