Hi

Thank for you reply. I have data which need to be transfered from MSSQL 2005 to Oracle 10g database. The data is storing with double-byte (i.e. chinese characters or other language characters). Therefore, I use nvarchar2 to store data.

I hope I can know further detail about this kind of unsupported datatype. And, I would like to get the alternatives with examples from you.

I look forward to receive your reply.

Cheers,
Gary
