convert(... using windows_1251_to_utf8) - works on cli, but not in a c prog.
Hello,
I'm programming a small Flash game with PostgreSQL 8.1.4
and phpBB serving as backend. The data in the database is
in windows_1251 encoding. For my game I have to convert
it into utf8, and at the command prompt it seems to work (I recon
this because 7 win1251 chars seem to produce 14 utf8 bytes):
phpbb=> show client_encoding;
client_encoding
-----------------
SQL_ASCII
(1 row)
phpbb=> select username from phpbb_users where user_id=179;
----------
Василий
(1 row)
phpbb=> select convert(username using windows_1251_to_utf8) from
phpbb_users where user_id=179;
convert_using
----------------
Р'асилий
(1 row)
But when I call the same command from my C program,
I get the result in Windows-1251 and not in utf8:
#define SQL_FETCH_USER \
"select (username using windows_1251_to_utf8), " \
"user_avatar from phpbb_users where user_active = 1 " \
"and user_id = $1 and user_password = $2 and user_id not in " \
"(select ban_userid from phpbb_banlist where ban_userid is not null)"
PQprepare(....);
PQexecPrepared(....);
[ and as result I get only 7 bytes, in Win1251 encoding:
%C2%E0%F1%E8%EB%E8%E9 ]
I realize that my question is a bit chaotic, but maybe someone
already knows, why wouldn't convert() work in my C program?
Otherwise I'll try to prepare a simple test case
Thank you
Alex
I started to prepare a test case and realized I had a bug.
So convert() works for me, sorry for my previous message!

In any case, it's probably saner if you SET client_encoding at the start
of the session instead of using convert() everywhere. The
server_encoding should be correctly set to Win1251 though! (Using
SQL_ASCII, while not technically incorrect, is probably not doing you
any favor).

thanks for your comment! I've dropped my db
and recreated it with encoding set to WIN1251:
pref:afarber> psql
Welcome to psql 8.1.4, the PostgreSQL interactive terminal.
.....
phpbb=> \l+
List of databases
Name | Owner | Encoding | Description
-----------+-------------+-----------+---------------------------
phpbb | _postgresql | WIN1251 |
postgres | _postgresql | SQL_ASCII |
template0 | _postgresql | SQL_ASCII |
template1 | _postgresql | SQL_ASCII | Default template database
(4 rows)
phpbb=> show client_encoding;
client_encoding
-----------------
WIN1251
(1 row)
Seems to work ok... My prepared query seems to work too:
#define SQL_FETCH_USER \
"select convert(username using windows_1251_to_utf8), " \
"user_avatar from phpbb_users where user_active = 1 " \
"and user_id = $1 and user_password = $2 and user_id not in " \
"(select ban_userid from phpbb_banlist where ban_userid is not null)"

Well, what I was suggesting (not explicitely enough, now that I look)
was that you SET client_encoding to UTF8, and then use the query this
way:
#define SQL_FETCH_USER \
"select username, " \
"user_avatar from phpbb_users where user_active = 1 " \
"and user_id = $1 and user_password = $2 and user_id not in " \
"(select ban_userid from phpbb_banlist where ban_userid is not null)"
Good to hear that it worked anyway.
