Recreate table

Code:

Database error in vBulletin 4.2.2:



Invalid SQL:



        INSERT INTO taggregate_temp_1492976820

                SELECT threadid, COUNT(*) AS views

                FROM threadviews

                GROUP BY threadid;



MySQL Error   : Can't find file: 'threadviews' (errno: 2)

Whats the query to recreate that table in vbulletin 4.2?
Thanks!

You can get it from the mysql-schema.php file, in the install folder.

Thanks!

The missing threadviews table caused the database to create lots of taggregate_temp_xxxx tables.
Is there sql query to delete them all at once? Because I cant manually delete them because phpmyadmin hangs when I tried to load the database. Thanks!

Unfortuatenly, there is no way to delete all those tables with one query.

You could do some trickery with information_schema though:

Alternatively you could run a simple script:

PHP Code:


		
			
require('./global.php');

$tables = $db->query_read("SHOW TABLES LIKE 'taggregate\_temp\__%'");
while ($table = $db->fetch_row($tables))
{
    $db->query_write("DROP TABLE `$table[0]`");
}

No guarantees whatsoever, eg. you should be prepared to have a backup ready if anything goes wrong :)

Thanks Andreas! Problem solved :)
More than 100,000 temp tables have been removed :D
