One of the downsides to this setup is we lose the power of a primary listing_id. The only way around that I could think of would be to have a separate listing table that kept track of what state an item was in and pointed to the primary key of that item in whatever state table it belonged too. You could just have a listing_id sequence that you get new numbers from and use that in your other tables. It can still be a primary key because it will be unique across your different tables. -- Postgresql php tutorials http://www.designmagick.com/ ---(end of broadcast)--- TIP 5: don't forget to increase your free space map settings

[GENERAL] UTF-8 context of BYTEA datatype??
Hi!
Within a UTF-8 encoded database, I have a table:
CREATE TABLE pics (id serial not null unique, img bytea);
The table is originally initialized with a set of IDs. Then I'm using
perl-script to insert apropriate images by means of UPDATEing rows:
--within my script called 'job'---
my $db = DBI-connect('DBI:Pg:dbname=mydb') or die DBI;
my $z = $db-prepare(UPDATE pics set img=? where id=?) or die
PREPARE;
my $rc = $z-execute($content, $FILEID) or die EXEC;
-
But the result is somewhat unexpected:
---console output--
DBD::Pg::st execute failed: ERROR: invalid byte sequence for encoding
UTF8: 0x89
EXEC at ./job line 22, chunk 1.

How come the bytearea is *interpreted* as having encoding?

Actually, it's not the bytea type that is being interpreted, it's the
string you're sending to the server that is. Before you send bytea data
in a query string, you have to bytea encode it first. The DBD::Pg
manpage seems to suggest something like:
$rv = $sth-bind_param($param_num, $bind_value,
{ pg_type = DBD::Pg::PG_BYTEA });
Hope this helps,

manpage seems to suggest something like:

Hmmm, despite initial euphoria, this doesn't actually work.
Subsequently I've also tried putting SQL_BINARY in place of that
hash-ref, and plain DBD::Pg::PG_BYTEA, and also I tried to use 'TYPE ='
instead of pg_type. (All those hints in man DBI). None of that worked
either.
But I also did:
$db-do('SET client_encoding = LATIN1') or die SET;
just after connect and before prepare, and this produced a slightly
different result no ERROR, but the image was cut short to 9-bytes
inside the database data-row.
Would perl have interpreted this command according to it's semantics?
And change it's own default string handling accordingly!?
Not knowing the internals, I wouldn't bet on whichever, but I have my
doughts - my quess is thet DBI driver doesn't go that far. So if it
hasn't interpretted the 'SET client_encodding' internally, but just
passed that to database, the only thing that changed is the database
frontend context.
So may be the original error came from the database itself anyway?
Any ideas? (still hopping I wont have to write a C-level interface

The record in ctable AND the record in ptable are both deleted even though I

Because there was only one record, the one in ctable, and you deleted
it. When you inserted the record into ctable that's the only place
it went. The query against ptable showed records in the parent
table (none) and records in its child tables (one). After you
delete the record from the child the subsequent query against the
parent returns zero rows because both tables are now empty (the
parent was always empty and the child had its one record deleted).

Re: [GENERAL] Restoring databases from a different installment on Windows
Berislav Lopac [EMAIL PROTECTED] wrote I have recently reinstalled my Windows mychine, including the PostgreSQL server, but (due to a system crash, unrelated to Postgres) I wasn't able to dump my databases to import them now. However, I have a full copy of the original system, including all the files of the original Postgres installation. Is there a way to restore the databases from the original installation into the new one? For example, in MySQL I would be able to just copy the data files; is there something similar in Postgres? If you don't have a tablespace built (i.e. all data are in your initial data directory), then just like MySQL, you can replace your current data directory with that folder.

At least for pt_BR (Brazilian Portuguese) there are lots of functions around that can be used. What they have of bad is that the names are expressed as an array inside the function itself. I believe that the suggestion was to use one of these functions -- for any language, with modifications for number gender, as said it is needed in arabian -- and instead of storing the names in an array storing them in a table would be interesting. I believe that this table should contain: - numbers from 0 to 20, 30, 40, 50, 60, 70, 80, 90, 100 (this has a variation in pt_BR), 200, 300, 400, 500, 600, 700, 800, 900, 1000 - suffixes for thousands, millions, billions, etc. - suffixes for fractions (cents, dimes, quarters, etc.) - gender (in pt_BR they are genderless, in pt the male gender is the dominant with regards to the language, so I'd define the male gender as default in a function...) - language (if this becomes a function to share with other people, I'd make English the default) - groupping character, decimal separator (in pt_BR and en_US they are reversed, for example) I don't see it easily done in a multi-language way due to several particularities of each language... If this is going to be used for money, things might get a bit harder (IIRC, in Portugal they have the money symbol after the integer part and before the decimal part, making it a new decimal separator...)...
