Question

My mysql query is not updating my database correctly can some one help me fix this problem I think it has something to do with the JOIN.

Here is my mysql query.

"UPDATE users 
 SET users.last_login = NOW() 
 FROM users JOIN info ON info.user_id = users.user_id 
 WHERE (info.email = '" . $e . "' OR users.username = '" . $e . "') 
 AND users.password = '" . $sha512 . "' 
 AND users.active IS NULL"

Here is the working query before I used the JOIN.

"UPDATE users SET last_login = NOW() WHERE (email = '" . $e . "' OR username = '" . $e . "') AND password = '" . $sha512 . "' AND active IS NULL"

Answer 1

Your query syntax is wrong. The syntax for cross-table update in MySQL is somewhat
different than T-SQL. It should be as below.

 UPDATE users JOIN info ON info.user_id = users.user_id
 SET users.last_login = NOW()   
 WHERE (info.email = '" . $e . "' OR users.username = '" . $e . "') 
 AND users.password = '" . $sha512 . "' 
 AND users.active IS NULL
