Hello guys, welcome to my new blog SQLrevisited. I have long back created this blog to exclusively share SQL and Database articles but never get time to start it until today. This is the first article on this blog and in this post, you will learn how to contact multiple columns in an SQL server.
Like Java and many other programming languages and databases, you can use the + operator to concatenate multiple columns in SQL Server. You can join as many columns as you want with the + operator but you must remember that concatenating with NULL will produce NULL, which means you can lose the information from other columns if one of them is NULL.
