如何在MySQL中使用其他域屏蔽用户电子邮件地址？
让我们首先创建一个表-
mysql> create table DemoTable1345 -> ( -> UserEmailAddress text -> );
使用insert命令在表中插入一些记录。我们在这里插入了电子邮件地址-
mysql> insert into DemoTable1345 values('Carol123@gmail.com');
mysql> insert into DemoTable1345 values('987Sam@gmail.com');
mysql> insert into DemoTable1345 values('David_Miller@gmail.com');
mysql> insert into DemoTable1345 values('Bob@gmail.com');使用select语句显示表中的所有记录-
mysql> select * from DemoTable1345;
这将产生以下输出-
+------------------------+ | UserEmailAddress | +------------------------+ | Carol123@gmail.com | | 987Sam@gmail.com | | David_Miller@gmail.com | | Bob@gmail.com | +------------------------+ 4 rows in set (0.00 sec)
以下是查询以掩盖MySQL中具有不同域的用户电子邮件地址-
mysql> update DemoTable1345 set UserEmailAddress=replace(UserEmailAddress, '@gmail.com','@amz.com'); Rows matched: 4 Changed: 4 Warnings: 0
让我们再次检查表记录-
mysql> select * from DemoTable1345;
这将产生以下输出-
+----------------------+ | UserEmailAddress | +----------------------+ | Carol123@amz.com | | 987Sam@amz.com | | David_Miller@amz.com | | Bob@amz.com | +----------------------+ 4 rows in set (0.00 sec)
