Few weeks back, I wrote a blog on CONCAT string function in SQL Server 2012. A user asked if the CONCAT function is similar to Space function in SQL Server and what is the difference between the two functions. I replied to him and clarified the difference of the 2 functions. After that I thought, it would be good to write a blog post on Space function too.
Space function is useful to return ‘x’ number of spaces, where ‘x’ is an integer. The syntax for the space function is space(x) where x is an integer. To understand the function lets us look a simple script with and without space function.
Without Space function
The below screen shot displays an output where 2 string values are concatenated without using space function and the resulting string is an output that may not be acceptable. See that the resulting string is a single string without any break between first and last name.
Using Space function
The below screen shot displays an output where 2 string values are concatenated and separated by space function. Using space(1) generated a single space (1 space) and when that is used in the string concatenation, output string is now better and acceptable.
