SQL querry to delete an entire category and threads inside

[geovadim]

Hello,

I need to delete many threads. I tried using admincp > forum manager > delete category. The server goes in timeout.

I need a querry to delete an entire category and threads inside as well.

I tried: DELETE FROM wp_posts WHERE post_category = 53;

I get the error desc: Table 'onlinesp_vb4.wp_posts' doesn't exist

I don't know what table prefix I have. I don't know to have any special table prefix.

May I get some help?
