How do I get first name and last name as whole name in a MYSQL query?

You can use a query to get the same:

SELECT CONCAT(FirstName , ' ' , MiddleName , ' ' , Lastname) AS Name FROM TableName;

Note: This query return if all columns have some value if anyone is null or empty then it will return null for all, means Name will return "NULL"

To avoid above we can use the IsNull keyword to get the same.

SELECT Concat(Ifnull(FirstName,' ') ,' ', Ifnull(MiddleName,' '),' ', Ifnull(Lastname,' ')) FROM TableName;

If anyone containing null value the ' ' (space) will add with next value.

SELECT CONCAT_WS(" ", `first_name`, `last_name`) AS `whole_name` FROM `users`
