Thank you for your answer. I tried to delete the threads from the inline moderation but I get a timeout. For three threads the database stalls for 1 minute almost. I need to delete 60.000 threads or so.

This is the error:
>Request Timeout
This request takes too long to process, it is timed out by the server. If it should not be timed out, please contact administrator of this web site to increase 'Connection Timeout'.

I have 2 databases. From the first one I must delete all the posts before the 27th on November 2012. After that I must merge this database with a second database which has posts and threads begging 2002 until the 27th of November 2012.
