Well do you have any connector available? I don't know Netezza at all.
Basically assuming there is a connector for Netezza for sql server you
setup a new connection to Netezza in sql server that you can transfer data
from Netezza to sql server using a sort of INSERT INTO TABLE SELECT ...
FROM NETEZZA TABLE.

Head code does. But if I understood you are converting everything to
characters and then back to database. Pay lot of attention to separators or
you risk to corrupt data!

A tool that would use just ODBC would do. I don't know any such tool.
Datacopy is written to transfer sql server to sql server only. And use
dblib which is bound to sql server.
