Query Tuning 101: How to Compare Execution Plans
 
04:12
When you're tuning SQL query there's two important questions to keep in mind: * Have my changes made any difference? * If they have, is performance better or worse? In this video we'll look at how you can use SQL Developer to compare execution plans. This will enable you to differences between them and determine which plan performs better. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

Oracle SQL Tuning - How to Read Execution Plans (Explain Plan)
 
13:39
In this free tutorial you will learn how to generate and read (interpret) an execution plan in Oracle Databases. See more FREE Oracle Tuning tutorials at http://skillbuilders.com/free-oracle-tutorials. Understanding what the Oracle Database does with your SQL is essential to tuning - and the execution plan is the key. Oracle Certified Master DBA John Watson will provide a brief introduction (4 minutes) - which includes John's tuning methodology, then demonstrate EXPLAIN PLAN, SQL*Plus AUTOTRACE and DBMS_XPLAN.DISPLAY_CURSOR. In the tutorial, John will teach you: - How to read an execution plan - Find the 1st step in the plan - Decipher the order of the steps in the plan - That EXPLAIN PLAN can be very misleading Prerequisites: To get the most from this tutorial, you should: 1 Know how to code SQL 2 Be familiar with SQL*Plus 3 Know - in very general terms - what an execution plan is. 4 Have a basic understanding of the Library Cache (this is where Oracle Database stores parsed SQL statements) 5 Have a basic understanding of the Cost Based Optimizer (this is the part of the database that parses your SQL, creates an execution plan. Hopefully the correct - most efficient - plan).

Identifying Long Running Queries
 
01:10:08
Tuning the performance of your queries in SQL Server can be a lot of work. However, in order for your systems to receive the full benefits of query tuning, you must tune the queries that need it the most. This session will show you three different methods for determining which of the queries on your system are being called the most frequently, take the longest period of time to run, or are using the most resources. You'll be able to use the information in this session to quickly set up your own metrics gathering processes in order to understand what is happening on your systems and which queries will benefit most from tuning. Grant Fritchey is a SQL Server MVP with over 20 years’ experience in IT including time spent in support and development. Grant has worked with SQL Server since version 6.0 back in 1995. He has developed in VB, VB.Net, C# and Java. Grant has authored books for Apress and Simple-Talk, and joined Red Gate as a Product Evangelist in January 2011.

Advanced SQL and the Power of Rewriting Queries
 
57:53
Presented by Tony Andrews, Themis Inc. Often times there can 4,5,6 different ways to write an SQL query and get the same results back. What makes one better than any of the others, and is there any ones that are always better, or always worse? Sometimes rewriting 1 predicate in an SQL statement can cause optimization to change. This presentation breaks down many examples of query rewrites and how they can affect performance and optimization. Being strong in SQL is a great skill when it comes to performance and tuning of queries. Tony Andrews has more than 25 years’ experience in the development of relational database applications. Most of this time, he has provided development and consulting services to Fortune 500 companies and government agencies. Tony has written literally thousands of queries and programs during his development years, and has also served as a database analyst. For the last 10 years, Tony has been splitting his time between performance and tuning consulting engagements along with training. His main focus is to teach today’s developers the ways of RDMS application design, development and SQL programming -- always with a special emphasis on improving performance. He is a current IBM Champion, and regular speaker at many regional user groups, IDUG NA, and IDUG EMEA. He is also the author of a book for developers titled ‘DB2 SQL Tuning Tips for z/OS Developers’.
