Обсуждение: problems with this wiew
Hi.
I've got a problem with this "wiew":
select gallery_id, multimedia_id
from (view_multimedia_file A inner join ( select gallery_id, multimedia_id,
element_type_id, result_type_id, subevent_id,
subevent_type_id, event_id, championship_id,
championship_type_id, season_id, c_language_id as language_id
from ( view_gallery B inner join ( select gallery_id as c_gallery_id,
result_type_id, subevent_id,
subevent_type_id, event_id,
championship_id, championship_type_id,
season_id, language_id as c_language_id
from view_gallery_result_type ) C on (B.gallery_id =
C.c_gallery_id) ) D
) E
on ( (A.mm_id = E.multimedia_id) )
);
select *
from (view_multimedia_file A inner join ( select gallery_id, multimedia_id,
element_type_id, result_type_id, subevent_id,
subevent_type_id, event_id, championship_id,
championship_type_id, season_id, c_language_id as language_id
from ( view_gallery B inner join ( select gallery_id as c_gallery_id,
result_type_id, subevent_id,
subevent_type_id, event_id,
championship_id, championship_type_id,
season_id, language_id as c_language_id
from view_gallery_result_type ) C on (B.gallery_id =
C.c_gallery_id) ) D
) E
on ( (A.mm_id = E.multimedia_id) )
);
The postgresql show error.
Anybody can help me, please??
Thank you very much.
Have a nice day ;-)

Well if you have spelled view "wiew" - that may be part of your problem, sincerely, Aasmund.

Since I don't know the definitions of his tables, I can't affirm what type of an error happened. But if his tables are correctly defined, his error is probably: ERROR: Column reference "***" is ambiguous. If so, the vague columns reference of his query ought to be adjusted with explicitly using aliases: B, C, and E (e.g. see below). select E.gallery_id, E.multimedia_id from view_multimedia_file A inner join (select B.gallery_id, B.multimedia_id, B.element_type_id, C.result_type_id, C.subevent_id, C.subevent_type_id, C.event_id, C.championship_id, C.championship_type_id, C.season_id, C.c_language_id as language_id from view_gallery B inner join(select gallery_id as c_gallery_id, result_type_id, subevent_id, subevent_type_id, event_id, championship_id, championship_type_id, season_id, language_id as c_language_id from view_gallery_result_type ) C on (B.gallery_id = C.c_gallery_id) ) E on (A.mm_id =E.multimedia_id) ; Regards, Masaru Sugawara
