I am using hibernate 3.0 and mysql 4.0.15.

I have some problems with turkish chars(i-with no dot, s-with dot and some others).
hibernate save records that include some of the chars above as '?'. for example when i save 'kamıl' it saves it like 'kam?l'.

Also i have an other question. after enabling show_sql i see the sql queries on the console but i cannot see the values like below.

insert into ...... values(?,?,?)

Hi, maybe the problme is absed on your JDBC Driver,
Java handles Strings as UTF (Unicode), so your Turkish characters will be visible without any problems on Java side.
I guess the problem is that the JDBC driver of Mysql does not save it as UTF in your mysql Table and tries to convert them without success.
Ther are 2 Ways to change this.
1. You add the usage of UTF to your JDBC driver
For this use in your hibernate config the following connection string:
jdbc:mysql://localhost/testchar?useUnicode=true&character
Encoding=utf8

or
2. You create your Table or Database per default with UTF encoding.
You may try with:

CREATE TABLE `testchar` (
`testchar` varchar(100) NOT NULL default ''
) ENGINE=MyISAM DEFAULT CHARSET=utf8;


This should help you.

That could be a problem with your database encoding (see posting above), but you should also use the following query style:






Use log4j.logger.org.hibernate.type=DEBUG in your log4j.properties. and the parameters will be logged as well.
