Hi
We are developing something like a social networking website. I've got task to do
'follow me' functionality. In our website objects are users, teams, companies, channels and groups (please don't ask why there are groups and teams - it is complicated for me too, but teams are releated to user's talent)
Users, teams, channels, companies and groups have all their own tables.
I have a query which gets me all the follower's leaders like this
select
--fo.leader_id,
--fo.leader_type,
us.name as user_name,
co.name as company_name,
ch.title as channel_name,
gr.name as group_name,
tt.name as team_name
from
follow_up fo
left join users us
on (fo.leader_id = us.id and fo.leader_type = 'user')
left join companies co
on (fo.leader_id = co.user_id and fo.leader_type = 'company')
left join channels ch
on (fo.leader_id = ch.id and fo.leader_type = 'channel')
left join groups gr
on (fo.leader_id = gr.id and fo.leader_type = 'group')
left join talent_teams tt
on (fo.leader_id = tt.id and fo.leader_type = 'team')
where
follower_id = 83
I need to get all fields like:
user_name,
company_name,
channel_name,
group_name,
team_name
as one field in SELECT's product.
I have tried to alias them all the same 'name' but Oracle numbered it.
Please help :)
