To concatenate more than one columns into a single value, we can user
CONCAT function like below. The good thing is that even if columns are of different types, it can be concatenated. Like we can concatenate string with integer, datetime etc.
SELECT CONCAT( FirstName, SPACE(1), LastName, SPACE(1), Age, space(2), Active ) FROm PersonalDetails
Here, we are concatenating FirstName a space separated by LastName one space separated by Age and two space separated by Active field from the PersonalDetails table.
