Alexander,
I believe this problem was fixed in the latest JDBC driver, that is
supposed to be shipped with 7.1. It asks your database which encoding
is used for particular database while connecting to the database. So
you should be able to see "select getdatabaseencoding" if you turn on
a debugging option for postmaster.
I also think the latest driver is compatible with 7.0.3, but I'm not
sure. Peter T?
It should be at the basic level, but methods in DatabaseMetaData will fail as
they are specific to 7.1's system table changes etc.

Subject: PostgreSQL JDBC Unicode Support

Message-ID: [EMAIL PROTECTED]
Tatsuo,
my name is Alex Vaysman, and I saw your numerous posts in the
newsgroups
regarding Postgres and mutli-language support. I have a problem with
our
Postgres database, and intensive searches on the Internet/newsgroups
didn't
provide me with an answer. I was wondering if you would know the
answer or
point me towards it.
In the nutshell, we are trying to get Postgres DB running that
supports
Unicode and interacts with clients via JDBC. We have PostgreSQL
version
7.0.3 installed. I have downloaded the latest JDBC driver from
http://jdbc.postgresql.org.
I have created a Unicode database (confirmed through \l command in
psql,
reported encoding is 'UNICODE'). In that DB I've created a table with
two
fields integer and varchar(64). Then I store a record into this table.
In my
code I specify the string through Unicode escapes. After that I
retrieve
this value and write it out. I don't get my value back but rather
?. I'm
attaching the code I use for reference.
My Internet searches for the solution indicated that I need to apply
some
patches to JDBC driver. However, I don't know how to do that. Do you
know
where I may download the JDBC driver version with the appropriate
patches
applied? If you're using one, would you be kind enough and e-mail it
to me.
Also, having some experience with SQL Server, I know that if I wanted
to
store Unicode values into some column I was creating that column as
nvarchar
rather the varchar. Is anything like this required for Postgres?
Your help is greatly appreciated. Thanks in advance,
Alex Vaysman.
