Solution 1

Not sure if I understand correctly but simply put a space in the separator string

SQL

CONCAT(Lastname,',',Firstname,' ',Middlename) as Fullname

However, remember that if any of the columns is null, the result is null. So you probably want to use

SQL

CONCAT(Lastname, ',', IFNULL(Firstname, ''), ' ' , IFNULL(Middlename, ''))
