Insert Euro and Dollar symbol to a column in MySQL?

MySQLMySQLi Database

For this, use CASE statement with UPDATE command. Let us first create a table −

mysql> create table DemoTable1874
   (
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   Amount varchar(100)
   );
Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1874(Amount) values('3450');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1874(Amount) values('190');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1874(Amount) values('7600');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1874(Amount) values('4500');
Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1874;

This will produce the following output −

+----+--------+
| Id | Amount |
+----+--------+
|  1 | 3450   |
|  2 | 190    |
|  3 | 7600   |
|  4 | 4500   |
+----+--------+
4 rows in set (0.00 sec)

Here is the query to insert Euro and Dollar symbol to a column in MySQL −

mysql> UPDATE DemoTable1874 SET Amount=
   CASE
      WHEN Id = 1 THEN Concat('$','',Amount)
      WHEN Id = 3 THEN Concat('€','',Amount)
   else
      Amount
      END
   ;
Query OK, 2 rows affected (0.00 sec)
Rows matched: 4  Changed: 2 Warnings: 0

Let us check the table records once again −

mysql> select * from DemoTable1874;

This will produce the following output −

+----+---------+
| Id | Amount  |
+----+---------+
|  1 | $3450   |
|  2 | 190     |
|  3 | €7600   |
|  4 | 4500    |
+----+---------+
4 rows in set (0.00 sec)
