BUG #3277: error occurs between different versions

The command line:

was working properly in Postgre SQL 8.0 but in version Postgre SQL 8.2 the
second "and" gives an error.
And it is :

" Project dym.exe raised exception class EPSQLDatabaseError with message
'PostgreSQL Error Code : (1)
ERROR: missing FROM-clause entry for table "onay_durum" at character 152'
.Process stopped.Use Step or Run to continue. "

I don't understand how that query could have worked on PostgreSQL 8.0
either. There's no table or alias with name "onay_durum" in the FROM clause.

Are you sure this is the exactly same query you tried on PostgreSQL 8.0?

Seems to be dependant on the config parameter add_missing_from. The default
changed between 8.0 and 8.1 from on to off.

Nilay, you can try setting add_missing_from=on in postgresql.conf and
reload the service to fix this. Or better yet, fix your query to reference
all tables in the from clause.

Didn't the default in postgresql.conf for add_missing_from change in 8.1?

Yes,it is the same query, and had worked on PostgreSQL8.0 ,but although I
had already added "onay_durum" to from clause and it did not work on 8.2,I
have changed the 'add_missing_from = off ' and made it on in conf. file but
it didn't work too.
I have no idea about what to do:(

Please keep the list CC'd so others can help.

There must be something wrong with the way you added onay_durum to the
FROM-clause, but it's impossible to say what without seeing the modified
query and error message. Just check the query again carefully.

I presume you meant that you changed 'add_missing_from = on', not off,
in the config file.

I'm suprised it worked in 8.0. You should have got column reference is
ambiguous errors on seri_no since it appears in both dokuman and
onay_durum and there are 3 places where you don't specify which one you
want. (Someone who knows more than I do might comment on what happens
to unqualfied field names when the add missing from brings in another
field with the same name?)

try fully qualifying where everything comes from.

select
??.seri_no,
???.ad as baslik,
????.kull_ref as Kullanıcı_Referansi,
?????.sorumlu

from onay,

dokuman,
onay_durum
where onay_durum.p_id='yonetici'
and onay.dokuman_id=dokuman.seri_no
and onay_durum.seri_no=??????.seri_no
and onay_durum.p_id='yonetici'
and (
dokuman.durum=1
or dokuman.durum=2
or dokuman.durum=6
or dokuman.durum=7)
and onay_durum.durum=0
and ???????.seri_no>0

klint.

Nothing --- it's always been the case that unqualified field names have
to reference one of the explicitly-listed FROM tables.
