MySQL query to display columns name first name, last name as full name in a single column?

For this, use CONCAT() method in MySQL. Let us first create a table −

mysql> create table DemoTable
(
   FirstName varchar(50),
   LastName varchar(50)
);
Query OK, 0 rows affected (0.63 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('Chris','Brown');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable values('David','Miller');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('John','Doe');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable values('Adam','Smith');
Query OK, 1 row affected (0.25 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-----------+----------+
| FirstName | LastName |
+-----------+----------+
| Chris     | Brown    |
| David     | Miller   |
| John      | Doe      |
| Adam      | Smith    |
+-----------+----------+
4 rows in set (0.00 sec)

Following is the query to concatenate first name and last name to full name −

mysql> select concat(FirstName,' ',LastName) AS FullName from DemoTable;

This will produce the following output −

+--------------+
| FullName     |
+--------------+
| Chris Brown  |
| David Miller |
| John Doe     |
| Adam Smith   |
+--------------+
4 rows in set (0.00 sec)
