DB2: How to set encoding for db2clp under Windows? - windows

Question

I have a DB2 that was created with encoding set to UTF-8
db2 create database mydb using codeset UTF-8
My data insert scripts are also stored in encoding UTF-8.
The problem now is that the command line processor seems to work with a different encoding as the Windows installation doesn't use UTF-8:
C:\Users\Administrator>chcp
Active code page: 850
This leads to the problem that my data (which contains special characters) is not stored correctly to the database.
Under Linux/AIX I could change the command line encoding by setting
export LC_ALL=en_US.UTF-8
How do I achieve this under Windows? I already tried
chcp 65001
UPDATE:
But that won't have any effect? It seems like the db2clp can't deal with the UTF-8 encoded file because it will print out junk:
D:\Program Files\ibm_db2\SQLLIB\BIN>chcp 65001
Active code page: 65001
D:\Program Files\ibm_db2\SQLLIB\BIN>type d:\tmp\encoding.sql
INSERT INTO MY_TABLE (ID, TXT) VALUES (99, 'äöü');
D:\Program Files\ibm_db2\SQLLIB\BIN>db2 connect to mydb
Datenbankverbindungsinformationen
Datenbank-Server = DB2/NT64 9.5.0
SQL-Berechtigungs-ID = MYUSER
Aliasname der lokalen Datenbank = MYDB
D:\Program Files\ibm_db2\SQLLIB\BIN>db2 -tvf d:\tmp\encoding.sql
INSERT INTO MY_TABLE (ID, TXT) VALUES (99, 'äöü')

Answer 1

You need to set both:
CHCP 65001
SET DB2CODEPAGE=1208
on the db2cmd command line, before running db2 -tvf. This works for databases that have CODESET set to UTF-8. To check the CODESET setup for database run:
db2 get db cfg for <your database>
and look for "Database code page" and "Database code set" they should be 1208 and UTF-8 respectively.

Answer 2

when dealing with encodings, you have to take a careful look into your envirnoments, and where you are currently. So in your case:
the Server stores its data in encoding A (like UTF-8)
the client resides in an environment which has encoding B (like windows-1252)
in your client, you have to have to use the encoding of your client (or tell the client you intentionally use another encoding on client side (like UTF-8-encoded file inside a windows-1251 environment)!). The connection between the Client and the server is doing the work for you to change encoding B into encoding A for storing the data into the database.

It's work for me by setting db2codepage, thanks to Mr. Zoran Regvart.
by the way, after setting, you need to execute "db2 terminate" to reset client, and then reconnect.
