0. 簡介
|
||||
|
||||
MB 支援是為了讓 PostgreSQL 能處理多位元組字元 (multi-byte character),
|
||||
例如: EUC (Extended Unix Code), Unicode (統一碼) 和 Mule internal code
|
||||
(多國語言內碼). 在 MB 的支援下, 你可以在正規表示式 (regexp), LIKE 及
|
||||
其他一些函式中使用多位元組字元. 預設的編碼系統可取決於你安裝 PostgreSQL
|
||||
時的 initdb(1) 命令, 亦可由 createdb(1) 命令或建立資料庫的 SQL 命令決定.
|
||||
所以你可以有多個不同編碼系統的資料庫.
|
||||
|
||||
MB 支援也解決了一些 8 位元單位元組字元集 (包含 ISO-8859-1) 的相關問題,
|
||||
(我並沒有說所有的相關問題都解決了, 我只是確認了迴歸測試執行成功,
|
||||
而一些法語字元在 MB 修補下可以使用. 如果你在使用 8 位元字元時發現了
|
||||
任何問題, 請通知我)
|
||||
|
||||
1. 如何使用
|
||||
|
||||
編譯 PostgreSQL 前, 執行 configure 時使用 multibyte 的選項
|
||||
|
||||
% ./configure --enable-multibyte[=encoding_system]
|
||||
% ./configure --enable-multibyte[=編碼系統]
|
||||
|
||||
其中的編碼系統可以指定為下面其中之一:
|
||||
|
||||
SQL_ASCII ASCII
|
||||
EUC_JP Japanese EUC
|
||||
EUC_CN Chinese EUC
|
||||
EUC_KR Korean EUC
|
||||
EUC_TW Taiwan EUC
|
||||
UNICODE Unicode(UTF-8)
|
||||
MULE_INTERNAL Mule internal
|
||||
LATIN1 ISO 8859-1 English and some European languages
|
||||
LATIN2 ISO 8859-2 English and some European languages
|
||||
LATIN3 ISO 8859-3 English and some European languages
|
||||
LATIN4 ISO 8859-4 English and some European languages
|
||||
LATIN5 ISO 8859-5 English and some European languages
|
||||
KOI8 KOI8-R
|
||||
WIN Windows CP1251
|
||||
ALT Windows CP866
|
||||
|
||||
例如:
|
||||
|
||||
% ./configure --enable-multibyte=EUC_JP
|
||||
|
||||
如果省略指定編碼系統, 那麼預設值就是 SQL_ASCII.
|
||||
|
||||
2. 如何設定編碼
|
||||
|
||||
initdb 命令定義 PostgresSQL 安裝後的預設編碼, 例如:
|
||||
|
||||
% initdb -E EUC_JP
|
||||
|
||||
將預設的編碼設定為 EUC_JP (Extended Unix Code for Japanese), 如果你喜歡
|
||||
較長的字串, 你也可以用 "--encoding" 而不用 "-E". 如果沒有使用 -E 或
|
||||
--encoding 的選項, 那麼編繹時的設定會成為預設值.
|
||||
|
||||
你可以建立使用不同編碼的資料庫:
|
||||
|
||||
% createdb -E EUC_KR korean
|
||||
|
||||
這個命令會建立一個叫做 "korean" 的資料庫, 而其採用 EUC_KR 編碼.
|
||||
另外有一個方法, 是使用 SQL 命令, 也可以達到同樣的目的:
|
||||
|
||||
CREATE DATABASE korean WITH ENCODING = 'EUC_KR';
|
||||
|
||||
在 pg_database 系統規格表 (system catalog) 中有一個 "encoding" 的欄位,
|
||||
就是用來紀錄一個資料庫的編碼. 你可以用 psql -l 或進入 psql 後用 \l 的
|
||||
命令來查看資料庫採用何種編碼:
|
||||
|
||||
$ psql -l
|
||||
List of databases
|
||||
Database | Owner | Encoding
|
||||

|
||||
euc_cn | t-ishii | EUC_CN
|
||||
euc_jp | t-ishii | EUC_JP
|
||||
euc_kr | t-ishii | EUC_KR
|
||||
euc_tw | t-ishii | EUC_TW
|
||||
mule_internal | t-ishii | MULE_INTERNAL
|
||||

|
||||

|
||||
test | t-ishii | EUC_JP
|
||||
unicode | t-ishii | UNICODE
|
||||
(9 rows)
|
||||
|
||||
3. 前端與後端編碼的自動轉換
|
||||
|
||||
[註: 前端泛指客戶端的程式, 可能是 psql 命令解譯器, 或採用 libpq 的 C
|
||||
程式, Perl 程式, 或者是透過 ODBC 的視窗應用程式. 而後端就是指 PostgreSQL
|
||||
資料庫的伺服程式]
|
||||
|
||||
PostgreSQL 支援某些編碼在前端與後端間做自動轉換: [註: 這裡所謂的自動
|
||||
轉換是指你在前端及後端所宣告採用的編碼不同, 但只要 PostgreSQL 支援這
|
||||
兩種編碼間的轉換, 那麼它會幫你在存取前做轉換]
|
||||
|
||||
encoding of backend available encoding of frontend
|
||||
--------------------------------------------------------------------
|
||||
EUC_JP EUC_JP, SJIS
|
||||
|
||||
EUC_TW EUC_TW, BIG5
|
||||
|
||||
LATIN2 LATIN2, WIN1250
|
||||
|
||||
LATIN5 LATIN5, WIN, ALT
|
||||
|
||||
MULE_INTERNAL EUC_JP, SJIS, EUC_KR, EUC_CN,
|
||||
EUC_TW, BIG5, LATIN1 to LATIN5,
|
||||
WIN, ALT, WIN1250
|
||||
|
||||
在啟動自動編碼轉換之前, 你必須告訴 PostgreSQL 你要在前端採用何種編碼.
|
||||
有好幾個方法可以達到這個目的:
|
||||
|
||||
o 在 psql 命令解譯器中使用 \encoding 這個命令
|
||||
|
||||
\encoding 這個命令可以讓你馬上切換前端編碼, 例如, 你要將前端編碼切換為 SJIS,
|
||||
那麼請打:
|
||||
|
||||
\encoding SJIS
|
||||
|
||||
o 使用 libpq [註: PostgreSQL 資料庫的 C API 程式庫] 的函式
|
||||
|
||||
psql 的 \encoding 命令其實只是去呼叫 PQsetClientEncoding() 這個函式來達到目的.
|
||||
|
||||
int PQsetClientEncoding(PGconn *conn, const char *encoding)
|
||||
|
||||
上式中 conn 這個參數代表一個對後端的連線, encoding 這個參數要放你想用的編碼,
|
||||
假如它成功地設定了編碼, 便會傳回 0 值, 失敗的話傳回 -1. 至於目前連線的編碼可
|
||||
利用以下函式查知:
|
||||
|
||||
int PQclientEncoding(const PGconn *conn)
|
||||
|
||||
這裡要注意的是: 這個函式傳回的是編碼的代號 (encoding id, 是個整數值),
|
||||
而不是編碼的名稱字串 (如 "EUC_JP"), 如果你要由編碼代號得知編碼名稱,
|
||||
必須呼叫:
|
||||
|
||||
char *pg_encoding_to_char(int encoding_id)
|
||||
|
||||
o 使用 PGCLIENTENCODING 這個環境變數
|
||||
|
||||
如果前端底設定了 PGCLIENTENCODING 這一個環境變數, 那麼後端會做編碼自動轉換.
|
||||
|
||||
[註] PostgreSQL 7.0.0 ~ 7.0.3 有個 bug -- 不認這個環境變數
|
||||
|
||||
o 使用 SET CLIENT_ENCODING TO 這個 SQL 的命令
|
||||
|
||||
要設定前端的編碼可以用以下這個 SQL 命令:
|
||||
|
||||
SET CLIENT_ENCODING TO 'encoding';
|
||||
|
||||
你也可以使用 SQL92 的語法 "SET NAMES" 達到同樣的目的:
|
||||
|
||||
SET NAMES 'encoding';
|
||||
|
||||
查詢目前的前端編碼可以用以下這個 SQL 命令:
|
||||
|
||||
SHOW CLIENT_ENCODING;
|
||||
|
||||
切換為原來預設的編碼, 用以下這個 SQL 命令:
|
||||
|
||||
RESET CLIENT_ENCODING;
|
||||
|
||||
[註] 使用 psql 命令解譯器時, 建議不要用這個方法, 請用 \encoding
|
||||
|
||||
4. 關於 Unicode (統一碼)
|
||||
|
||||
統一碼和其他編碼間的轉換可能要在 7.1 版後才會實現.
|
||||
|
||||
5. 如果無法轉換會發生什麼事?
|
||||
|
||||
假設你在後端選擇了 EUC_JP 這個編碼, 前端使用 LATIN1, (某些日文字元無法轉換成
|
||||
LATIN1) 在這個狀況下, 某個字元若不能轉成 LATIN1 字元集, 就會被轉成以下的型式:
|
||||
|
||||
(十六進位值)
|
||||
|
||||

[Here is a good documentation explaining how to use WIN1250 on
|
||||
Windows/ODBC from Pavel Behal. Please note that Installation step 1)
|
||||
is not necceary in 6.5.1 -- Tatsuo]
|
||||

||||
Version: 0.91 for PgSQL 6.5

||||
Sorry for my Eglish and C code, I'm not native :-)
|
||||
|
||||
!!!!!!!!!!!!!!!!!!!!!!!!! NO WARRANTY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
|
||||
|
||||
Instalation:
|
||||
------------
|
||||
1) Change three affected files in source directories
|
||||
(I don't have time to create proper patch diffs, I don't know how)
|
||||
2) Compile with enabled locale and multibyte set to LATIN2
|
||||
3) Setup properly your instalation, do not forget to create locale
|
||||
variables in your profile (environment). Ex. (may not be exactly true):
|
||||
LC_ALL=cs_CZ.ISO8859-2
|
||||
LC_COLLATE=cs_CZ.ISO8859-2
|
||||
LC_CTYPE=cs_CZ.ISO8859-2
|
||||
LC_MONETARY=cs_CZ.ISO8859-2
|
||||
LC_NUMERIC=cs_CZ.ISO8859-2
|
||||
LC_TIME=cs_CZ.ISO8859-2
|
||||
4) You have to start the postmaster with locales set!
|
||||
5) Try it with Czech language, it have to sort
|
||||
5) Install ODBC driver for PgSQL into your M$ Windows
|
||||
6) Setup properly your data source. Include this line in your ODBC
|
||||
configuration dialog in field "Connect Settings:" :
|
||||
SET CLIENT_ENCODING = 'WIN1250';
|
||||
7) Now try it again, but in Windows with ODBC.
|
||||
|
||||
Description:
|
||||
------------
|
||||
- Depends on proper system locales, tested with RH6.0 and Slackware 3.6,
|
||||
with cs_CZ.iso8859-2 loacle
|
||||
- Never try to set-up server multibyte database encoding to WIN1250,
|
||||
always use LATIN2 instead. There is not WIN1250 locale in Unix
|
||||
- WIN1250 encoding is useable only for M$W ODBC clients. The characters are
|
||||
on thy fly re-coded, to be displayed and stored back properly
|
||||
|
||||
Important:
|
||||
----------
|
||||
- it reorders your sort order depending on your LC_... setting, so don't be
|
||||
confused with regression tests, they don't use locale
|
||||
- "ch" is corectly sorted only in some newer locales (Ex. RH6.0)
|
||||
- you have to insert money as '162,50' (with comma in aphostrophes!)
|
||||
- not tested properly

Sorry for my Eglish and C code, I'm not native :-)
|
||||
|
||||
!!!!!!!!!!!!!!!!!!!!!!!!! NO WARRANTY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
|
||||
|
||||
Instalation:
|
||||
------------
|
||||
1) Change three affected files in source directories
|
||||
(I don't have time to create proper patch diffs, I don't know how)
|
||||
[PostgreSQL 6.5.1$B$G$O$3$N%9%F%C%W$OI,MW$"$j$^$;$s!%(B-- $B@P0f(B]
|
||||
2) Compile with enabled locale and multibyte set to LATIN2
|
||||
3) Setup properly your instalation, do not forget to create locale
|
||||
variables in your profile (environment). Ex. (may not be exactly true):
|
||||
LC_ALL=cs_CZ.ISO8859-2
|
||||
LC_COLLATE=cs_CZ.ISO8859-2
|
||||
LC_CTYPE=cs_CZ.ISO8859-2
|
||||
LC_MONETARY=cs_CZ.ISO8859-2
|
||||
LC_NUMERIC=cs_CZ.ISO8859-2
|
||||
LC_TIME=cs_CZ.ISO8859-2
|
||||
4) You have to start the postmaster with locales set!
|
||||
5) Try it with Czech language, it have to sort
|
||||
5) Install ODBC driver for PgSQL into your M$ Windows
|
||||
6) Setup properly your data source. Include this line in your ODBC
|
||||
configuration dialog in field "Connect Settings:" :
|
||||
SET CLIENT_ENCODING = 'WIN1250';
|
||||
7) Now try it again, but in Windows with ODBC.
|
||||
|
||||
Description:
|
||||
------------
|
||||
- Depends on proper system locales, tested with RH6.0 and Slackware 3.6,
|
||||
with cs_CZ.iso8859-2 loacle
|
||||
- Never try to set-up server multibyte database encoding to WIN1250,
|
||||
always use LATIN2 instead. There is not WIN1250 locale in Unix
|
||||
- WIN1250 encoding is useable only for M$W ODBC clients. The characters are
|
||||
on thy fly re-coded, to be displayed and stored back properly
|
||||
|
||||
Important:
|
||||
----------
|
||||
- it reorders your sort order depending on your LC_... setting, so don't be
|
||||
confused with regression tests, they don't use locale
|
||||
- "ch" is corectly sorted only in some newer locales (Ex. RH6.0)
|
||||
- you have to insert money as '162,50' (with comma in aphostrophes!)
|
||||
- not tested properly
