Thanks for quick reply.
This is Custom Post type and usin Table-based storage and it have only custom fields.
So should this work without inserting the rows ALSO to wp_posts? Or do I have to add the same rows also to wp_posts?
What I want to do is make own table (different from wp_posts table) for about 70.000 rows. And then make listings from these rows.
I don′t like to add them to wp_post, because this data will be updated daily and it is not good to do so in wp_posts table…
