AS400 DB2 national characters into SQL Server linked server

Question

I have a SQL Server 2012 Enterprise edition linked server connection to an IBM AS400 DB2 database. I am using the IBMDASQL provider for the connection.

I have problems with some Hungarian characters: the letter Ő is converting to O during the select.

In this example the name_converted column will be OK, the Ő letter remains Ő .

The name column will be converted to O .

SELECT * FROM openquery (g,
   SELECT 
       cast(name as char(35) ccsid 870) as name_converted,
       name,
   FROM libr.mytable')

My question is: can I create the linked server so that all the character is using the CCSID 870?

EXEC master.dbo.sp_addlinkedserver @server = N'G', @srvproduct = N'HUN00101', @provider  = N'IBMDASQL', @datasrc = N'HUN00101'

EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'G', @useself=N'False', 
            @locallogin=NULL, @rmtuser=N'query', @rmtpassword='########' 
GO

EXEC master.dbo.sp_serveroption @server = N'G', @optname = N'collation compatible', 
                                @optvalue = N'false' 
GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'data access', @optvalue=N'true' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'dist', @optvalue=N'false' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'pub', @optvalue=N'false' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'rpc', @optvalue=N'false' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'rpc out', @optvalue=N'false' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'sub', @optvalue=N'false' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'connect timeout', @optvalue=N'0' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'collation name', @optvalue=null GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'lazy schema validation', @optvalue=N'false' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'query timeout', @optvalue=N'0' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'use remote collation', @optvalue=N'true' GO
EXEC master.dbo.sp_serveroption @server=N'G', @optname=N'remote proc transaction promotion', @optvalue=N'true' GO

Thanks

It looks like the data may not have been properly tagged with CCSID 870 on the IBM i system. Can you try using the "Force Translate" custom property and setting it to 870? Note: This will cause all data not properly tagged with a CCSID to be handled as CCSID 870.
