为此，您可以使用MD5()。让我们首先创建一个表-mysql> create table DemoTable1887
(
Password text,
HashPassword text
);
使用插入命令在表中插入一些记录-mysql> insert into DemoTable1887(Password) values('John@9089');
mysql> insert into DemoTable1887(Password) values('90987_Carol');
mysql> insert into DemoTable1887(Password) values('656464_David_4343');
使用插入命令在表中显示一些记录-mysql> select * from DemoTable1887;
这将产生以下输出-+-------------------+--------------+
| Password | HashPassword |
+-------------------+--------------+
| John@9089 | NULL|
| 90987_Carol | NULL|
| 656464_David_4343 | NULL|
+-------------------+--------------+
3 rows in set (0.00 sec)
这是使用名称的md5版本更新所有条目的查询：mysql> update DemoTable1887 set HashPassword=md5(Password);
Rows matched: 3 Changed: 3 Warnings: 0
让我们再次检查表记录：mysql> select * from DemoTable1887;
这将产生以下输出-+-------------------+----------------------------------+
| Password | HashPassword |
+-------------------+----------------------------------+
| John@9089 | 7f92a7e09ab1a0cd3f36ec164f035c9a |
| 90987_Carol | 1578fa8c47f0e53a898c8ada5c0111b4 |
| 656464_David_4343 | e5ec2bd2cb55b2252be7ca9eb546659e |
+-------------------+----------------------------------+
