outer joins to more than one table
Hi everybody,
I had to do this :
select thf.idhtmlfile as idPage,twa.idwebtemplatesareas as idarea,
twa.name as name,twa.t_row as t_row,toc.content as content,
toc.name as title,ta.tagxml as tag
from tblarea ta,tblhtmlfile thf,tblwebtemplatesareas twa,
tblonlinecontent toc,tbltemplateandcontent ttc
where thf.idtemplate=twa.idwebtemplate
and ta.idarea=twa.idarea
and toc.idonlinecontent=ttc.idonlinecontent
and thf.idhtmlfile=ttc.idhtmlfile(+)
and twa.idwebtemplatesareas=ttc.idwebtemplatesareas(+)
order by idpage,twa.idarea asc;
but U can not outer join a table to more than one table so I was wondering how can this be done.
Is this right :
select tg1.idhtmlfile as idPage,tg1.idwebtemplatesareas as idarea,
tg1.name as name,tg1.t_row as t_row,tg2.content as content,
tg2.name as title,tg1.tagxml as tag
from tblonlinecontent toc,tbltemplateandcontent ttc,
(select ta.tagxml,ta.idarea,thf.idhtmlfile ,
idwebtemplatesareas,twa.name,twa.t_row
from tblarea ta,tblhtmlfile thf,tblwebtemplatesareas twa
where ta.idarea=twa.idarea and thf.idtemplate=twa.idwebtemplate) tg1,
(select ttc.idhtmlfile,ttc.idwebtemplatesareas,toc.content,toc.name
from tblonlinecontent toc,tbltemplateandcontent ttc
where toc.idonlinecontent=ttc.idonlinecontent) tg2
where tg1.idhtmlfile=tg2.idhtmlfile(+)
and tg1.idwebtemplatesareas=tg2.idwebtemplatesareas(+)
order by idpage,tg1.idarea asc
or this one is right:
select thf.idhtmlfile as idPage,twa.idwebtemplatesareas as idarea,
twa.name as name,twa.t_row as t_row,toc.content as content,
toc.name as title,ta.tagxml as tag
from tblarea ta,tblhtmlfile thf,tblwebtemplatesareas twa,
tblonlinecontent toc,tbltemplateandcontent ttc,tbltemplateandcontent ttc2
where thf.idtemplate=twa.idwebtemplate
and ta.idarea=twa.idarea
and toc.idonlinecontent=ttc.idonlinecontent
and thf.idhtmlfile=ttc.idhtmlfile(+)
and twa.idwebtemplatesareas=ttc2.idwebtemplatesareas(+)
order by idpage,twa.idarea asc;
They give different results and I don't actually know why?
Can anyone have a look at it please.
Thank you
