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");
?>

Comments
  • first of all, your syntax is invalid. Second, describe better what are you trying to do?
  • "password" as md5 is 5f4dcc3b5aa765d61d8327deb882cf99
  • Thanks @sergiot, I used this UPDATE Users SET password = MD5(password); with slight modification for my database and it worked like a charm! This saved me from updating every record manually... :)
  • Small hint: If the new password (hash) is the same like the existing - the sql result will show you: 0 row will be affected ;)
  • I do not understand why this is voted down. This question has "php" tag and upper code solves it clearly.
  • stackoverflow sometimes just pisses me of! i ask a genuine quesiton here and i get voted down by some so called 'reputable users' who think they are the best at everything!!!
