So maybe I was not precise enough, but it seems we still have two bugs: one with trimming multibute characters (which happens when databse is capable of storing them as normal CHARs), the other with replacing them with '?' (when the database cannot store them as CHAR, but still should process them correctly as NCHAR). And as I do not have the administration rights on the database I use for tests (and can not change the encoding), I'll have to cope with mine bug first before I can even test yours. ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

So: Gr8. At least I know why I have problems getting this to work on MS.Net: it won't work. (see http://support.microsoft.com/default.aspx?scid=kb;en-us;322158# ) I'd have to use their exact versions of Oracle8, none other are basicly supported... so cross-testing this problem on windows is not possible. On the other hand - after reading other people's mail, it seems to me that all who experience the trimming have Oracle database setup as UTF8. Mine works in EEMSWIN1250 (you can check this with "SELECT value FROM nls_database_parameters WHERE parameter='NLS_CHARACTER_SET';"). This, however, should not be an issue, as NVARCHAR2 is meant for storing Unicode data even when the database does not operate in UTF8 (consult http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10749/ch6unicode.htm#i1007039). So there is ANOTHER bug, this one presenting only with non-UTF8 databases... Oh shit. Somewhere before the string gets inserted, mono (or OCI) replaces all non-ascii chars with character number 63 (yes, the question mark). [btw - I read the results through nunit gui runner, or KDE Konsole, both of which display UTF8 fine.] ___ Mono-devel-list mailing list Mono-devel-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-devel-list

He may not be able to help with Oracle, but he knows unicode very well. jonp is another good person to to talk to. If possible, write a Windows.Forms application with a rich text box or a Gtk# application with a TextView and output your result there. This is so unicode characters will show up for you.

I have started (finally!) to work on this bug. The test I am currently using fails, with or without patch... although in an unexpected way. On mono, it breaks with: Failures: 1) MonoTests.System.Data.OracleClient.Oci.OciDefineHandleTest.TrimsWideUnicodeStringsTest : Directly passed value mismatched String lengths are both 25.

The string doesn't get trimmed. I suppose this is a problem with the setup of my Oracle database. To verify, I tried to run the code on MS.Net 1.1.

It *can* be, to encode the entire 31-bit address space of UCS-4, but since IIRC they limited Unicode & ISO 10646 to be a 21-bit character set you'll generally only see 3-byte long UTF-8 sequences as a maximum.

Re: [Mono-dev] Maybe a System.Data.OracleClient.dll bug
Could you please clarify this? If I get you right, you mean that the
code in the repository does not work, and mono 1.1.17.1 does not
work.
Surely the code will work if you do it as a single sql statement (if
it does not, things are FUBAR ;-) ), but it is (in regard to
performance) better to use OracleParameter. Inserting values into the
query string manualy is a workaround, but an ugly one, if you ask me.
Yes,I mean the OracleParameter bugs still exist in the newest version
of System.Data.OracleClient.dll and Mono 1.17.1.
Can you please send me both the code you use to create the table and
the c# code you have tried to execute? And information about such
things as locale settings, encoding and so on, both on your machine
and in the database?
code are:
using System;
using System.Data ;
using System.Data.OracleClient;
namespace Test{
class MainEntry{
public static void Main(string[] args){
String connString = "server=video;User Id=mono;password=jcyjcy";
String insertSql = "INSERT INTO test(name) values (:name)";
OracleConnection conn = new OracleConnection(connString);
try{
conn.Open();
OracleCommand command = new OracleCommand();
command.Connection = conn;
command.CommandText = insertSql;
command.CommandType = CommandType.Text;
OracleParameter parm = new OracleParameter(":name",
OracleType.NVarChar);
// insert a Chinese string into table test(the
string's length is 4)
parm.Value = "测试插入";
command.Parameters.Add(parm);
command.ExecuteNonQuery();
}
catch(Exception ex){
Console.WriteLine(String.Format("Error is: {0}",ex.Message));
}
finally{
conn.Close();
}
}
}
}

create table test (name nvarchar2(1000)

Re: [Mono-dev] Maybe a System.Data.OracleClient.dll bug
You have to have the column as NVarchar, Which is national character
set, It saves all data as unicode (utf8) instead of ASCII

I use System.Data.OracleClient to connect and operate oracle database;
But I find a problem when inserting into oracle database with chinese
character;
Here is a simple exapmle:
using System;
using System.Data ;
using System.Data.OracleClient;
namespace Test{
class MainEntry{
public static void Main(string[] args){
String connString = "server=video;User Id=mono;password=jcyjcy";
String insertSql = "INSERT INTO test(name) values (:name)";
OracleConnection conn = new OracleConnection(connString);
try{
conn.Open();
OracleCommand command = new OracleCommand();
command.Connection = conn;
command.CommandText = insertSql;
command.CommandType = CommandType.Text;
OracleParameter parm = new OracleParameter(":name",
OracleType.VarChar);
// insert a Chinese stiing into oracle database(the string's
length is 4)
parm.Value = "测试插入";
command.Parameters.Add(parm);
command.ExecuteNonQuery();
}
catch(Exception ex){
Console.WriteLine(String.Format("Error is:
{0}",ex.Message));
}
finally{
conn.Close();
}
}
}
}
and the create table is :
create table test(name varchar(1000));
in sqlplus :
select * from test;
You will see the result is not we expected,not all the character insert into
the database.
Can't anybody tell me how to resolve this problem?
