Re: How to insert Chinese (big5) through JDBC?

Hi,
I can now insert Chinese!!
I'm now using EUC_TW as the database encoding.
However, the default client encoding is now EUC_TW. (that's why I cannot insert Chinese). I have to exe "set client_encoding to 'Big5';" when inserting and selecting.

Can I set Big5 as the default client_encoding ?

Best Regards,

Hi Kris Jurka,

When initializing the data, I can move the big5 data from MSSQL7 and insert into the postgresql database through VB. Why?

Another case: I write the insert statement to the debug file. I can read the Chinese there. If I copy and paste in "putty", I can also insert those Chinese correctly.

Thus, I guess the problem is inserting through JDBC.

You cannot store Big5 data in a SQL_ASCII encoded database. Consider
using UNICODE. Also the ?charset=xxx argument in the database URL is no
longer valid in the Postgresql JDBC drivers starting with 7.3.
