Set Country Code to Phone Numbers in MySQL

To set country code to phone numbers would mean to concatenate. You can use CONCAT() for this.

Let us first create a table −

mysql> create table DemoTable769 (MobileNumber varchar(100));
Query OK, 0 rows affected (0.54 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable769 values('8799432434');
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable769 values('9899996778');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable769 values('7890908989');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable769 values('9090898987');
Query OK, 1 row affected (0.20 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable769;

This will produce the following output -

+--------------+
| MobileNumber |
+--------------+
| 8799432434   |
| 9899996778   |
| 7890908989   |
| 9090898987   |
+--------------+
4 rows in set (0.00 sec)

Following is the query to set country code to column values with phone numbers in MySQL −

mysql> update DemoTable769
   set MobileNumber=concat('+91',MobileNumber);
Query OK, 4 rows affected (0.20 sec)
Rows matched: 4 Changed: 4 Warnings: 0

Let us check the description of the view −

mysql> select *from DemoTable769;

This will produce the following output -

+---------------+
| MobileNumber  |
+---------------+
| +918799432434 |
| +919899996778 |
| +917890908989 |
| +919090898987 |
+---------------+
4 rows in set (0.00 sec)
