Question

i am trying to get data from four tables with respect to the the “type”. Types can be comment, cover pic change, friend request accept etc. but the problem is the query i made is not working by repeating the types for all and timestamp for all. the query i made is

SELECT c.up_date, c.user_id, c.id, f.id,
       f.up_date, f.friend1, f.friend2, f.status,
       s.postdate, s.status, s.id, s.display_name, s.userid, s.userid1, s.type,
       c.type, f.type
FROM cover_pic c, wp_userstatus s, wp_friends f
WHERE s.userid = f.friend1
AND s.userid = c.user_id
AND f.status =3
AND c.user_id =4
ORDER BY s.postdate
LIMIT 0 , 30

can anyone help me with the right query with respect to timestamp and the type

here is the result its giving me

what i want

timestamp userid_id id display_name type

233232323 1 1 paramveer comment

1212121212 1 2 paramveer coverpic

Answer 1

Maybe you want an union of joins

(select distinct s.postdate as postdate, s.userid, c.id, c.type
 from wp_userstatus s
 join cover_pic c on s.userid = c.user_id)
union
(select distinct s.postdate, s.userid, f.id, f.type
 from wp_userstatus s
 join wp_friends f on s.userid = f.friend1)
order by postdate
limit 30

It’s really hard to tell.
