How to mask user email addresses with a different domain in MySQL?
Let us first create a table −
mysql> create table DemoTable1345
-> (
-> UserEmailAddress text
-> );
Query OK, 0 rows affected (0.42 sec)
Insert some records in the table using insert command. We have inserted email address here −
mysql> insert into DemoTable1345 values('Carol123@gmail.com');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable1345 values('987Sam@gmail.com');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable1345 values('David_Miller@gmail.com');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1345 values('Bob@gmail.com');
Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1345;
This will produce the following output −
+------------------------+
| UserEmailAddress |
+------------------------+
| Carol123@gmail.com |
| 987Sam@gmail.com |
| David_Miller@gmail.com |
| Bob@gmail.com |
+------------------------+
4 rows in set (0.00 sec)
Following is the query to mask user email addresses with different domains in MySQL −
mysql> update DemoTable1345 set UserEmailAddress=replace(UserEmailAddress, '@gmail.com','@amz.com');
Query OK, 4 rows affected (0.18 sec)
Rows matched: 4 Changed: 4 Warnings: 0
Let us check the table records once again −
mysql> select * from DemoTable1345;
This will produce the following output −
+----------------------+
| UserEmailAddress |
+----------------------+
| Carol123@amz.com |
| 987Sam@amz.com |
| David_Miller@amz.com |
| Bob@amz.com |
+----------------------+
4 rows in set (0.00 sec)
