MySQL query to update all entries with md5 version of name?
For this, you can use MD5(). Let us first create a table −
mysql> create table DemoTable1887 ( Password text, HashPassword text ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1887(Password) values('John@9089');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1887(Password) values('90987_Carol');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1887(Password) values('656464_David_4343');
Query OK, 1 row affected (0.00 sec)Display some records in the table using insert command −
mysql> select * from DemoTable1887;
This will produce the following output −
+-------------------+--------------+ | Password | HashPassword | +-------------------+--------------+ | John@9089 | NULL| | 90987_Carol | NULL| | 656464_David_4343 | NULL| +-------------------+--------------+ 3 rows in set (0.00 sec)
Here is the query to update all entries with md5 version of name:
mysql> update DemoTable1887 set HashPassword=md5(Password); Query OK, 3 rows affected (0.00 sec) Rows matched: 3 Changed: 3 Warnings: 0
Let us check the table records once again:
mysql> select * from DemoTable1887;
This will produce the following output −
+-------------------+----------------------------------+ | Password | HashPassword | +-------------------+----------------------------------+ | John@9089 | 7f92a7e09ab1a0cd3f36ec164f035c9a | | 90987_Carol | 1578fa8c47f0e53a898c8ada5c0111b4 | | 656464_David_4343 | e5ec2bd2cb55b2252be7ca9eb546659e | +-------------------+----------------------------------+ 3 rows in set (0.00 sec)
