MySQL Error 1054

I have a small site developed in vBulletin and MySQL. I am having problem with this site. I am getting the error message as "MySQL error: 1054 - Unknown column 'languagesId' in 'field list'". I recently upgraded my database to MySQL 5.0. How can I get rid of MySQL error 1054?

This is a small bug in MySQL 5. It occurs if you are using LEFT JOIN in your query. If you want to get rid of this error message then temporarily don't use LEFT JOIN in your query. I hope developer of MYSQL will sooner come up with some patches or something that will fix this problem.

Check your config.php file and make sure it is similar to as given below:

Quote:

---

'dbconfig' =>
array (
'db_host_name' => 'localhost',
'db_host_instance' => '',
'db_user_name' => 'opaper',
'db_password' => 'opaper',
'db_name' => 'opaper',
'db_type' => 'mysql', ),

---

Here replace "opaper" with your user name, password and database name respectively.

Simply change your query to one below (for example):

Code:

---

SELECT id, field1, field2, field3
FROM ( table1, table2 )
LEFT OUTER JOIN condition1
ON condition2
WHERE condition3;

---

So the most important changes that you should implement is use parenthesis in your FROM clause.
