How to replace a part of the string (domain name after @) using MySQL?

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> EmailId varchar(30)
   -> );
Query OK, 0 rows affected (0.53 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('John123@example.com');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('John123@gmail.com');
Query OK, 1 row affected (0.26 sec)
mysql> insert into DemoTable values('John123@yahoo.com');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable values('John123@example.com');
Query OK, 1 row affected (0.10 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+---------------------+
| EmailId             |
+---------------------+
| John123@example.com |
| John123@gmail.com   |
| John123@yahoo.com   |
| John123@example.com |
+---------------------+
4 rows in set (0.00 sec)

Here is the query to replace a part of the string −

mysql> update DemoTable
   -> set EmailId=replace(EmailId,'John123@example.com','John123@gmail.com');
Query OK, 2 rows affected (0.16 sec)
Rows matched: 4 Changed: 2 Warnings: 0

Let us check the table records once again −

mysql> select *from DemoTable;

This will produce the following output −

+-------------------+
| EmailId           |
+-------------------+
| John123@gmail.com |
| John123@gmail.com |
| John123@yahoo.com |
| John123@gmail.com |
+-------------------+
4 rows in set (0.00 sec)
