In this blog post we are going to learn about Identity Fields Review.
Why buy this Book: The beta of this book actually existed for a year and was tested and used in my classroom. Its purpose back then was to help the students do the steps individually that led to the skills where they could all pass the Microsoft test. It worked and then many went out for their SQL interview. They did good enough to get the job, but they told me about one or two questions they were not able to answer. A year of collecting this data and turning them into lessons doubled the size of this book of 300 pages to 600 pages. This book is designed to make the query question and query skills in the professional work must seem easier. Let us learn about Identity Fields Review.
Recently I noticed a very interesting question on Stackoverflow. A user wanted to add a particular column between two of the rows. He had an experience with MySQL so he was attempting following syntax. Following syntax will throw an error. Let us explore more about how to add column at specific locations in the table.
One of my friends who works in a big MNC recently asked me that if there is any way to check if the String is Palindrome or not. The palindrome is a word, phrase, or sequence that reads the same backward as forward. For example A man, a plan, a canal – Panama! is palindrome so as Was it a car or a cat I saw?
My first reaction was to him was why does this kind of functionality. His answer was they have requirement in their business application where they are building captcha and they may display the image in mirror image as well as a part of challenge code and he can’t have any word which is palindrome as an option. For this he wanted to write a script which will go letter by letter and match them. If they are same, he will not use the word for captcha.
Here is a very interesting question asked on the blog by Karthik. I really liked the question and I would like to discuss this here about SSMS doe snot Print NULL values.Â
