Hi .
I have a problem with reading some Strings from a XML file (unicode encoding)
and storing them into database.
what i do is :
I read my nodes content into a String variable and then pass it to
the SQL statement , then i execute the statement.what i get in database is just ??? for my fields with unicode content.
does any one help me to solve it ?
thank you very much
The database is Daffodil , i set database encoding to Unicode when i create it
