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).

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.

This video is for beginners who have never worked with SQL Developer, and we are going to teach how to begin writing queries. So the queries we are going to start with are queries when we give the database an expression and it will return back some kind of value.
The most common keyword you are going to need to know for Oracle is SELECT. SELECT is the command we use to get data from the database. Even though we have not really put any data in our database, we can still use the SELECT statement to get data. That's because the database is capable of doing more than just creating tables and retrieving data from tables.
So our first goal is to essentially write a Hello World, which just displays the text hello world to us.
A good place to start is with:
SELECT 'Hello World'
This would actually work for many database management systems, but when you run it you will get an error. This actually doesn't work with Oracle, it will tell us we always need the FROM keyword. To get around this, there is a magical table called DUAL. We can put anything we want to SELECT and then say FROM DUAL and it will work.
SELECT 'Hello World' FROM DUAL
We can also do math:
SELECT 1+1 FROM DUAL
And we can run even run functions:
SELECT SYSTIMESTAMP FROM DUAL
To put all of this together, you can grab all of this data at the same time using commas to separate different columns from our generated table:
SELECT 'Hello World', 1+1, SYSTIMESTAMP FROM DUAL

The Magic of SQL
Do you use EXPLAIN PLAN to tune Oracle SQL? Does it always "tell the truth", or does it "lie". (Maybe it's not the whole truth!) In this free tutorial from SkillBuilders' Oracle Certified Master John Watson, you will learn why the execution plan generated by EXPLAIN PLAN can be misleading and what to do about it. After a brief lecture, John demonstrates exactly why. You'll hear about dynamic sampling, adaptive cursor sharing (11g), adaptive execution plans (12c) and of course, bind variables. John demonstrates how bind variables cause misleading execution plans using dbms_xplan.display and dbms_xplan.display_cursor. To get the most from this tutorial, you should have some understanding of hard parse, soft parse, cardinality, histograms.

A job object (job) is a collection of metadata that describes a user-defined task that
is scheduled to run one or more times.
It is a combination of what needs to be executed (the action) and when (the schedule).
CREATE OR REPLACE PROCEDURE myproc AS

END myproc;

The execution plan for a SQL statement can often seem complicated and hard to understand. Determining if the execution plan you are looking at is the best plan you could get or attempting to improve a poorly performing execution plan can be a daunting task, even for the most experienced DBA or developer. This session examines the different aspects of an execution plan, from selectivity to parallel execution, and explains what information you should be gleaming from the plan and how it affects the execution. It offers insight into what caused the Optimizer to make the decision it did as well as a set of corrective measures that can be used to improve each aspect of the plan.

Explain plan is a wonderful utility in Oracle PL SQL. It helps you to understand how much cost a query takes to perform based on indexed table or table without index. In this oracle tutorial a full description is given on a table containing huge number of rows first based on index on a column and then without index.

One of SQL Developer’s most popular features has undergone a significant upgrade. Users can quickly define and recall delimited or Excel files to be imported to a new or existing Oracle table. Data preview and validation is provided for each column, as well as ‘best guess’ data type and date format mask mapping. This process can now be automated via the SQL Developer command line interface (SDCLI) ‘Import’ command. NOTE: This is a video only. There is no audio.
