SELECT CONCAT(empfname, '  ', emplname) AS fullname FROM namesInfo;

CONTACT is a function in a database that accepts multiple columns or strings as arguments and concatenates them to create a single column or string value. A comma is placed between the arguments.

In the above query, the function CONTACT is used to display the first name and the last name as a single full name. In order to separate the first name and the last name in the resulting full name column, a space character, in single quotes (' '), is used between the arguments of the CONTACT function in the query.
