I hardly get hard time to come up with the title of the blog post. This was one of the blog post even though simple, I believe I have not come up with appropriate title: Group by Rows and Columns using XML PATH – Efficient Concating Trick. Anyway, here is the question I received.
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.
When I was writing this blog post I had a hard time to come up with the title of the blog post so I did my best to come up with one. Here is the reason why? I wrote a blog post earlier SQL SERVER – Find First Non-Numeric Character from String. One of the questions was that how that blog can be useful in real life scenario. This blog post is the answer to that question. Let us first see a problem.
In SQL Server 2012, there are two new string functions being introduced, namely: CONCAT(), FORMAT(). In this blog post we are going to learn about String Function CONCAT(). CONCAT takes a minimum of two arguments to concatenate them, resulting to a single string.
