Someone else pointed it out already, but perhaps it's worthwhile repeating:
LuaSQL
http://www.keplerproject.org/luasql/
Also:
LuaDBI
http://code.google.com/p/luadbi/
Both support Oracle to various degree.
If you write your own Oracle interface, one would hope that you will provide a LuaSQL compatible API as a courtesy :)
As far as result set goes, here is the API I personally find convenient [1]:
local aDB = DB( 'sqlite3://localhost/test.db' )
for aContact in aDB( 'select * from contact' ) do
print( aContact.name, aContact.email )
end
FWIW, bellow is a more fullfledge example, with associated DML:
