This example illustrates how to append the values of some columns.

We use the 'CONCAT' function to append values of some columns and make it a single value as a result. In this example, we are concatenating  the value of "first_name" column and the value of "last_name" column for each row having value 'lucknow' in the 'city' column of the "roseindia" table.

Table "roseindia":

+----+------------+------------+------------+------------+---------+-------------+------+
| id | first_name | last_name  | start_date | end_date   | city    | description | age  |
+----+------------+------------+------------+------------+---------+-------------+------+
| 1  | sandeep    | suman      | 2008-12-25 | 2010-06-25 | lucknow | Programmer  | 24   |
| 2  | amit       | raghuvansi | 2007-11-22 | 2010-04-21 | lucknow | Programmer  | 25   |
| 3  | amar       | patel      | 2006-10-12 | 2007-05-12 | lucknow | Programmer  | 26   |
+----+------------+------------+------------+------------+---------+-------------+------+

Query to concatenate fist_name and last_name values:

Query

SELECT CONCAT(first_name, " ", last_name) from roseindia where city = 'lucknow';

Output

+------------------------------------+
| CONCAT(first_name, " ", last_name) |
+------------------------------------+
| sandeep suman                      |
| amit raghuvansi                    |
| amar patel                         |
+------------------------------------+
