Hey Keith,

Sorry, not quite. I should have been more specific. Here is the table I
have:

HouseRooms(int houseId, varchar type, varchar description)

What I want to find out are the homes that have the rooms that I desire.
So if I wanted a home with a grand bedroom, regular study, and an
ensuite bathroom, I would have to join the table with itelf many times
as such:

SELECT distinct houseId
FROM
HouseRooms AS Bedroooms,
HouseRooms AS Bathrooms,
HouseRooms AS Studies
WHERE
Bedrooms.houseId = Bathrooms.houseId
AND Bathrooms.houseId = Studies.houseId
AND Bedrooms.type = 'grand'
AND Bedrooms.description = 'bedroom'
AND Bathrooms.type = 'ensuite'
AND Bathrooms.description = 'bathroom'
AND Studies.type = 'regular'
AND Studies.description = 'study';


This joins the table with itself and produces homes that have ALL of
these different rooms. I need to do this in torque, but I have no idea
how. Aliasing maybe?


Thanks,


Chris
