A Story of Indexes and Full Table Scans: Finding All the Red Sweets Part 1
 
08:43
"Why isn't Oracle using my index?!" is a common question people have when tuning SQL queries. In this episode Chris compares two methods for finding all the red candies from party bags he's prepared. He shows how these are like a full table scan and an index range scan. He goes on to compare the performance of these two approaches. He shows when a full table scan becomes more efficient than an index range scan and vice versa. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

Thinking in Parallel
 
01:02:25
The Java 8 Streams library makes it easy to run code in parallel. A common error is code that works when run sequentially but that misbehaves when run in parallel. This is often caused by programmers who are stuck in a mode of imperative, left-to-right thinking. This leads to an iterative style in which data is mutated and where the next result depends on the result of the previous computation, creating barriers to parallel computation. This presentation covers an alternative programming technique called array programming, where operations are applied on data aggregates instead of individual elements. It also includes examples and demonstrations that illustrate these techniques and how they lead to easier-to-understand, parallel-ready code.

Explaining the Explain Plan: Interpreting Execution Plans for SQL Statements
 
01:04:02
Presenter: Maria Colgan, Oracle Corporation 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.

Getting Started with PL/SQL Table Functions: Pipelined Table Functions

Pipelined table functions are table functions in which rows are returned or "piped" back to the calling query before the function has completed, avoiding the blocking behavior of normal PL/SQL functions and reduce PGA consumption. This video is part of the Oracle Dev Gym class "Getting Started with Table Functions". You can watch it independent of the class, but then you miss out on the tutorials and quizzes!

Demonstrating Oracle DB Elapsed Time and Wall Time With Parallel Query
 
03:37
Is it really true? In my recent postings I wrote that when using parallel query a SQL statement's wall time is roughly equal to its elapsed time divided by the number of parallel query slaves. To check I ran an experiment and posted the results. The results are both obvious and illuminating. If you don't want to read but just sit on the couch and watch a video, you're in luck! I created a special video clip demonstrating what I wrote about. The main video clip is from my OraPub Online Institute video seminar, Tuning Oracle Using An AWR Report - Part 1. (NOT Part 2 as the video shows) From my blog posting: http://blog.orapub.com/20140907/watch-oracle-database-elapsed-time-and-wall-time-with-parallel-query.html For more information on OraPub r for more great education, go to www.orapub.com
