blog posts not showing up after import
 

I'm building custom modules through impex for a blog.
I have successfully imported blog categories.
Now carefully examine other application's modules I've noticed that
In order to import blog posts I will need to
import head blog posts except comments nor replies into `blog_text` first
then grab the last insert ID of the inserted row (blogid), and insert a new row into `blog` table with the blogid that I retrieved.

SO FAR SO GOOD HOWEVER,,,

ALL MY POSTS DOES NOT SHOWING UP IN THE FRONTEND.
Seriously, am I missing anything?

If this is cache issue, Is there anything I can clear the BLOG cache in the adminCP?

has anyone successfully imported blog without any problems??
