I want to be able to select a distinct group of rows from 2 tables and then once selected to group and total the results from the previous sql statement I have been trying the following
select a.id_fk_accommodation, a.id_fk_selection,a.type,sum(1) from acommodationlog a, log l where (id_fk_accommodation) in (select distinct a.id_fk_accommodation, a.id_fk_selection, a.type, l.sessionid from accommodationlog a, log l where a.id_fk_log = l.id_pk and id_fk_accommodation = 159 ) group by a.id_fk_accommodation,a.id_fk_selection,a.type I know this won't work due to incorrect number of columns in the in statement but how do I achieve the above Any help appreciated Thanks Regards David Inglis ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
