This lock can be like Pseudo table which is placed to avoid global deadlock conditions, read, write, access and exclusive lock. You can read more about Teradata Locks. Row retrieval Strategy:- From explain plan you will get the information about how Teradata will retrieve the rows from the disks.
As we know there may be several access paths to fetch data. Based on the availability of the index , Teradata may fetch rows by full table scan, using primary index , using secondary index or any other access path.
Here RowHash match scan means one row is retrieved from the first table; hash code of that row is used to locate the row from the other table. So for join processing rows should be in the same AMP.
Teradata decides to redistribute, duplicate to bring the rows to be joined on the same AMP. Join information:- In case of join operation, explain plan will show you what kind of join operation is chosen by the optimizer base on the situation.
You will see something like product join, single partition hash join, merge join etc. I am releasing my first book for Teradata V14 Basics Certification today.
I will release a new certification book each month until you are a Teradata Certified Master. The only place you can download the first Teradata V14 Basics book is directly from me, but by November 1st, it will be available on the top 27 book sites around the world including Safari, Skillsoft Books 24 x 7 , and site.
Since it is an e-book, you will be able to see it on your Kindle or any other e-reader device. You will receive an electronic PDF today that is watermarked with your name on it should you decide to download. You are going to love this book because your confidence and knowledge will soar.
It has been designed to help you pass the test, but it is so much more.
It is an incredible reference guide, learning tool, and foundation for passing all the tests and becoming a Teradata Certified Master. Sign up and watch the videos directly on my website, or anyone with a Safari membership can watch the videos by searching on Safari for "Coffing Studios".
I have already sold the video series to some of the largest Teradata customers in the world, and they are reporting to me that the videos are motivating, entertaining, interesting, and an effective learning tool. Although people love my books, I have never considered myself a writer.
I was a national speech champion not a national writing champion, so compliments on my video teaching are so very rewarding. Every chapter I teach, I try to make clear, dynamic, and fun. I have designed the certification books to visually paint pictures of each concept because the Teradata certification tests have proved to be extremely difficult to pass.
The first test on Teradata basics covers almost every subject under the sun.
