How to put multiples results in just one column

Hi,

The problem is, I'm working in a list of hotels which should have
availability of rooms and list the hotel and its rooms on the application.

I have this function which already is used to get the rooms available
select cms.sp_get_supplier_availability(2, '2013-02-01', '2013-02-02',
'pt_BR', 1, '{1}')

which result is a list of rooms ( type ) for a specific hotel.

("Apartment single",2117,"Apartamento
Superior",1681,4,10,100.00,100.00,100.00,127.32,127.32,3,1,{1},)"
"("Apartment single 2",4981,"Apartamento
Superior",1681,6,10,100.00,100.00,100.00,149.80,149.80,5,1,{1},)"
"("Apartment double",13862,"Apartamento
Luxo",4311,11,10,100.00,100.00,100.00,107.99,107.99,2,1,{1},)"
"("Suite double",13867,"Suíte
Executiva",4313,15,10,100.00,100.00,100.00,174.32,174.32,1,1,{1},)

I need to get one result of hotel's table and a way to return all the rows
available in a single column as a array with all the data showed below.

Is that possible?

thank you,
