Question

I’m having a bit of trouble figuring out how to make a query to achieve the following situation. I want a user to be able to view their events and activities (two different tables), along with any events/activities of organizations they belong to sorted by date

Events Table

eventID |  eventTitle   | eventBy   | eventDate
1           Event 1        1          2012/10/11
2           Event 2        2          2012/10/08
3           Event 3        3          2012/10/05

Activities table

postID     |   postTitle  |  postBy  |    postDate
  1            activity 1       1          2012/10/07
  2            activity 2       2          2012/10/09   

orgMembers table

orgID  |  userID
 2             1            //userID 1 is a member of groupID 2

Anyway, I’m trying to get the results to look be the following if userid 1 is viewing the page

 Title            By            Date
Activity 1        1          2012/10/07
Event 2           2          2012/10/08
Activity 2        2          2012/10/09
Event 1           1          2012/10/11

This query results in ONLY my posts only showing, not the organization that I’m a member of too.

select eventTitle as title, eventID as ids, eventBy as byUser, users.username, eventDate as date from events
inner join users on users.userid = events.eventBy
where eventBy in (select distinct g1.userID from orgMembers g1
                 inner join orgMembers g2 on g1.orgID = g2.orgID
                 where g2.userID = '$id') 
                 or eventBy = '$id' 

UNION 

select postTitle as description, postID as ids, postBy as byUser, users.username, postDate as date from posts
inner join users on users.userid = posts.postBy
where postBy in (SELECT distinct g1.userID FROM orgMembers g1
                 inner join orgMembers g2 on g1.orgID = g2.orgID
                 where g2.userID = '$id') 
                 or postBy = '$id'

Order BY date"

Answer 1

using

WHERE eventby IN 

replace 1 with your user id

you might want to use UNION to select from 2 tables events and activities

(select eventInfo as Ttile,eventBy as By, eventDate as Date from Events where Eventby in (SELECT userid FROM groups WHERE groupid = (SELECT groupid FROM groups WHERE userid = 1)))
UNION
(select activityInfo as Ttile,activityInfo as By, activityDate as Date from Activities where activityBy in (SELECT userid FROM groups WHERE groupid = (SELECT groupid FROM groups WHERE userid = 1))) Order BY Date

do the same with activities and the do union and sort
