Developing SQL Queries for Oracle® Databases: Hands-On

An Advanced Workshop
 
Course: 234   Duration: 4 Days
 
 

You Will Learn How To

  • Formulate complex queries with Oracle SQL
  • Apply the full range of complex query types
  • Use the analytic OLAP functions of Oracle
  • Test SQL queries completely
  • Select the most efficient solution to complex SQL problems
  • Choose between Oracle and ANSI style joins

Course Benefits

SQL forms the cornerstone of all relational database operations. Taking full advantage of its power requires an in-depth understanding of the language. In this course, you learn to use the full potential of SQL to write complex queries for Oracle databases. You gain the practical skills to choose the best query method for each application to ensure accuracy and avoid common errors or pitfalls.

Who Should Attend

Consultants, engineers, developers, analysts and others who are developing systems using Oracle databases. Course 926, "Oracle Database 11g Comprehensive Introduction", Course 593, "Oracle Database 10g Comprehensive Introduction", or equivalent SQL knowledge is assumed.

Hands-On Training

Exercises provide you with practical experience formulating complex queries, including:
  • Developing and testing queries with SQL Developer or SQL*Plus
  • Handling NULL values in expressions and conditions
  • Simplifying complex expressions with virtual columns in Oracle 11g
  • Joining multiple tables with ANSI standard or native Oracle syntax
  • Applying CASE & DECODE to simulate IF...THEN...ELSE
  • Producing statistics and aggregate results
  • Embedding subqueries in expressions
