SQL Query depending on another query

Question

I'm trying to make a query that returns the result of two different querys.

I have this one :

'test'

to return :

SELECT idtravel, travel, status FROM travel_db.travel
inner join travel_db.status
on travel.status_idstatus=status.idstatus
order by idtravel desc

Also have this query :

idtravel | travel | status
1          London   Completed
2          NY       Planned
3          Lisbon   Completed

which returns :

select sum(value) as total
from
( select a.value
from desp_housing a
where travel_idtravel = 1
union all
select t.value
from desp_transport t
where travel_idtravel = 1
union all
select tu.value
from desp_turism tu
where travel_idtravel = 1
) z

My point is to merge this two querys to have something like this :

Value
600

Can anyone help?

*Edit 13-05-15: After some ideas, i'm one field short from my final result. Here's where i'm at :

idtravel | travel | status    | Value
1          London   Completed   600
2          NY       Planned     1500
3          Lisbon   Completed   150

to return :

select idtravel, travel, sum(value) as total
from travel_db.travel 
inner join
( select a.travel_idtravel, a.value
from desp_housing a
union all
select t.travel_idtravel, t.value
from desp_transport t
union all
select tu.travel_idtravel, tu.value
from desp_turism tu
union all
SELECT idtravel, travel
FROM travel_db.travel
) z
on travel.idtravel=z.travel_idtravel
group by travel_idtravel

It's only missing the field status

*Edit 14-05-15: Guys, finaly it's completed.

Here's the final query :

idtravel | travel | value
1          London   600
2          NY       1500
3          Lisbon   150

returning :

Select idtravel, travel, sum(value) as total, status
From travel_db.travel
inner join
(select a.travel_idtravel, a.value, a.status_idstatus
from desp_housingo a
union all
select t.travel_idtravel, t.value, t.status_idstatus
from desp_transport t
union all
select tu.travel_idtravel, tu.value, t.status_idstatus
from desp_turism tu
union all
select idtravel, travel, status_idstatus
from travel_db.travel
) z
on travel.idtravel=z.travel_idtravel
inner join travel_db.status
on travel.status_idstatus=status.idstatus
group by travel_idtravel

The thing is, because of how the query is made you have to select fields that you are not going to use (a.status_idstatus, t.status_idstatus, t.status_idstatus) to ensure that you have the same number of fields. Maybe can be optimized but for now is working.

Answer 1

How about this?

getPosts

or you replace INNER JOIN with LEFT JOIN if your secondary columns may not have a value for all travel ids.

Answer 2

Assuming that parseFloat field belongs to idtravel and serves as a foreign key to all travel_db.travel tables.
