Adding/ concatenating text values within a MySQL SELECT clause?

MySQLMySQLi Database

To add/ concatenate text values within a select clause, you can use concat() function.

Let us create a table

mysql> create table ConcatenatingDemo
   -> (
   -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> UserName varchar(20),
   -> UserCountryName varchar(20)
   -> );
Query OK, 0 rows affected (0.82 sec)

Now you can insert some records in the table using insert command. The query is as follows −

mysql> insert into ConcatenatingDemo(UserName,UserCountryName) values('John','US');
Query OK, 1 row affected (0.14 sec)
mysql> insert into ConcatenatingDemo(UserName,UserCountryName) values('Carol','UK');
Query OK, 1 row affected (0.13 sec)
mysql> insert into ConcatenatingDemo(UserName,UserCountryName) values('Bob','AUS');
Query OK, 1 row affected (0.15 sec)
mysql> insert into ConcatenatingDemo(UserName,UserCountryName) values('David','US');
Query OK, 1 row affected (0.29 sec)

Display all records from the table using select statement. The query is as follows −

mysql> select *from ConcatenatingDemo;

The following is the output

+--------+----------+-----------------+
| UserId | UserName | UserCountryName |
+--------+----------+-----------------+
|      1 | John     | US              |
|      2 | Carol    | UK              |
|      3 | Bob      | AUS             |
|      4 | David    | US              |
+--------+----------+-----------------+
4 rows in set (0.00 sec)

Here is the query for adding/ concatenating text values within a SELECT clause

mysql> select concat(UserName,' belongs to ( ',UserCountryName,' )') as AddingTextDemo from ConcatenatingDemo;

The following is the output

+-------------------------+
| AddingTextDemo          |
+-------------------------+
| John belongs to ( US )  |
| Carol belongs to ( UK ) |
| Bob belongs to ( AUS )  |
| David belongs to ( US ) |
+-------------------------+
4 rows in set (0.00 sec)
