Analytical Functions in oracle explained with real examples
 
25:24
This video explains analytical functions and how they are implemented in real projects. Analytical functions are somewhat similar to aggregate functions,but they offer much more. Why use analytical function ? They allow you to write fast and concise queries which otherwise will involve self join and long processing times They allow you to perform aggregate functions independently on sets of partitions. You can access values from previous rows in current row and you can restrict the window on which you want to apply this analytical function. I have given additional practice exercises along with the dataset so that you can comfortably work with analytical functions. You can find the sample problems along with dataset in the below link. http://www.internshipsfromhome.com/oracle-analytical-functions-ddl-and-dml/

Why Won't Oracle Use My Index - 12c Attribute Clustering - Lesson 1
 
01:46
Sometimes a poor clustering factor is the cause when Oracle Database cost based optimizer does not choose to use an index. With Oracle 12c (12.1.0.2 EE) offers a new feature that can really help - "Atrribute Clustering". This is implemented with a new keyword on CREATE TABLE - "CLUSTERING BY LINEAR ORDER". In this Free Tutorial from SkillBuilders and Oracle Certified Master DBA John Watson, you'll get a brief refresher on clustering factor and a demonstration of CREATE TABLE - "CLUSTERING BY LINEAR ORDER" - so the CBO will use your index! In this first lesson, John will provide a brief review of clustering factor. See all 6 lessons - FREE - at http://www.skillbuilders.com/12c-attribute-clustering

Unavailable index index becomes available methods are: 1. Place the index can not be truncate operation corresponding table; 2.rebuild index; In addition, the query optimizer can use conversion method expand table so that the SQL statement has encountered unusable index partition table to generate better execution plans.

Main-Memory Join Algorithms: Sort or Hash?
 
01:17:58
The classical wisdom is that hashing is preferred method to implement joins in main memory. But this wisdom is now many years, if not decades, old and hardware has evolved considerably in the meantime. In this talk I will discuss join strategies for execution in main memory, including hash and sort-merge variants. The runtime characteristics of either strategy depends critically on a suitable implementation that respects the intricacies of modern hardware architectures. I will show how hash and sort-merge joins can be implemented to maximally benefit from hardware features like vector processing (SIMD), multi-level caches, multi-core parallelism, or NUMA-style memory arrangement. And I will point to pitfalls that could mis-guide conclusions about the �best� join implementation strategy. The join implementations discussed outperform the state of the art in join processing by several factors. Experiments on modern hardware platforms indicate that the sort-merge strategy is about to surpass hashing in upcoming hardware architectures�which might put classical wisdom upside-down.

Understanding Data Distribution with Pivotal Greenplum
 
12:40
Pivotal Greenplum distribution is determined at table CREATE time by selecting a distribution key of one or more columns. Typically you would use a table’s primary key or some other unique column or set of columns as the distribution key. There are two distribution policies for dividing the rows among the available Greenplum segments: Hash and Random. External tables do not have a distribution policy associated with them as they are outside the realm of control of Pivotal Greenplum. This is the first video of the Greenplum Concept Series lead by Dr. Venkatesh Raghavan, Principal Technical Product Manager.

Does SQL table join order matter?
 
14:10
Have you ever wondered if the order of the tables in your FROM clause matter? In today's video, we look at why theoretically table join order *does* make a difference for performance and why SQL Server doesn't use the order you provide. We also look at different techniques for forcing SQL Server to use the join order you specified.

Cost Based Optimizer in Apache Spark 2 2 -  Ron Hu &  Sameer Agarwal
 
35:20
Apache Spark 2.2 ships with a state-of-art cost-based optimization framework that collects and leverages a variety of per-column data statistics (e.g., cardinality, number of distinct values, NULL values, max/min, avg/max length, etc.) to improve the quality of query execution plans. Leveraging these reliable statistics helps Spark to make better decisions in picking the most optimal query plan. Examples of these optimizations include selecting the correct build side in a hash-join, choosing the right join type (broadcast hash-join vs. shuffled hash-join) or adjusting a multi-way join order, among others. In this talk, we'll take a deep dive into Spark's cost based optimizer and discuss how we collect/store these statistics, the query optimizations it enables, and its performance impact on TPC-DS benchmark queries.

How Does the Phyiscal Location of Rows Affect Indexes?: Finding All the Red Sweets Part 2
 
09:25
In part one of the red candy series, Chris compared the efficiency of using a index range scan and full table scan to access data. He found that a full table scan was more efficient when fetching more rows than there are table blocks. This analysis made a big assumption however. It worked on the presumption that there was no correlation between the order of candies in the document and which the bags they were in. In this episode tests this assumption. Chris looks at how the physical order of rows in a table can affect the efficiency of indexes on it. He discusses how Oracle tracks this via the clustering factor. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.
