I didn’t read the query, only the requirement for subqueries. J

Hi Teddy,

Thanks for the suggestion. I’ll give it a go and see if it works.

Doug,
Couldn't this be simply re-written as:

select
    *
from
    jobs j
    join jobLocation l
        k.jobID = l.jobID
where
    j.category = x
    and
    j.type = y
    and
    l.locationID = z

And use the linked table notation in the <objects /> to use the join query notation to get what Gareth is looking for?

This sounds to me like a case where it would be most appropriate to write a custom query.

Hi Doug,

My apologies if this has already been covered, but I couldn't see anything about this in the list archive.

I'm building a search on a jobs table, in which the user can specify a number of optional criteria

e.g.

SELECT *

FROM jobs

WHERE category=X

AND type=Y

……

Doing this in reactor, I've found the getByFields(), or using an OOP query in the gateway to work very well.

My problem, is that each job can belong to several locations – this is modelled in the DB using a 'location' table and linking via 'jobLocation' table.

Normally I would use a subquery to allow the user to narrow search results to a particular location e.g.

SELECT *

FROM jobs

WHERE category=X

AND type=Y

AND jobID IN (SELECT jobID FROM jobLocation WHERE locationID=Z)

Is this possible with reactor?

If not, it's no problem as I can very easily build a custom method into my job gateway

Thanks
