SQL Update of MD5 Passwords
I am new to PHP & SQL. I am trying to update a password from my database and I cant figure out the SQL statement so I done some research and came across this SQL statement:
UPDATE `Users` SET password= passwordmd5 (password)
I then added a bit more to the code as follows:
UPDATE `Users` SET password= tony123 MD5 (password) WHERE user_id = 55
I get the following error:
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'MD5 (password) WHERE user_id = 55' at line 1
What do I do?
Correct syntax would be this:
UPDATE Users SET password = MD5('tony123') WHERE user_id = 55;
Or, if you were storing password in plain text and you want to convert them to hashes, do this:
UPDATE Users SET password = MD5(password);

this will work after you add db connection strings to your php file:
<?php $password = 'tony123'; $passwordmd5 = md5($password); $q = mysql_query("UPDATE `Users` SET password = '$passwordmd5' WHERE user_id = 55"); ?>

0 row will be affected;)
