Adding characters in values for an existing int column in MySQL?


To add characters to an existing int column values, use MySQL CONCAT(). Let us first create a table −

mysql> create table DemoTable
(
   Amount int
);
Query OK, 0 rows affected (1.44 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values(709);
Query OK, 1 row affected (0.67 sec)
mysql> insert into DemoTable values(34560);
Query OK, 1 row affected (0.30 sec)
mysql> insert into DemoTable values(90854);
Query OK, 1 row affected (0.28 sec)
mysql> insert into DemoTable values(3456);
Query OK, 1 row affected (0.15 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+--------+
| Amount |
+--------+
|    709 |
|  34560 |
|  90854 |
|   3456 |
+--------+
4 rows in set (0.00 sec)

Following is the query to add characters in column values −

mysql> select concat('The Product Amount is=',Amount) AS AddingCharacters from DemoTable;

This will produce the following output −

+-----------------------------+
| AddingCharacters            |
+-----------------------------+
| The Product Amount is=709   |
| The Product Amount is=34560 |
| The Product Amount is=90854 |
| The Product Amount is=3456  |
+-----------------------------+
4 rows in set (0.00 sec)
