Question

I have to remove data and count for facebbok like notification. there are 3 tables from where i need to remove data
1st company table where i remove company id.
2nd table is mark_question where i mark the question as read/unread, fav/unfav, notification status
3rd is the forum topic questions where the data regarding the questions asked

1st query is removed on the result of a query where i get a set of values.

select * 
       from gl_mark_ques 
       where user_id =".$this->session->userdata('user_id')." and 
             vs_ques_status=0

after this i get a set of id’s these id’s should not be present in the next query i execute

SELECT uc.*,count(mq.vs_ques_status) 
       from gl_user_comp as uc 
       inner join gl_mark_ques as mq 
             on uc.user_id=mq.user_id and 
                uc.comp_id='$comp_id' 
       where mq.user_id<>".$this->session->userdata('user_id')." and 
             mq.new_ques_id!=2 and 
             mq.vs_ques_status=1

mq.new_ques_id=2 <– here i need to add the id’s i got from first query. There may be only one id or multiple id’s. How do i integrate this kindly help, thanks in advance

 SELECT uc.*,count(mq.vs_ques_status) as cnt_status_advhub 
from gl_user_comp as uc inner join gl_mark_ques as mq 
on uc.user_id=mq.user_id and uc.comp_id='$comp_id' 
where mq.user_id<>".$this->session->userdata('user_id')." and 
mq.vs_ques_status=1 and mq.new_ques_id NOT IN 
(select new_ques_id from gl_mark_ques where user_id 
=".$this->session->userdata('user_id')." and vs_ques_status=0)
