One cannot generalize from tsql to odbc because ODBC requires
additional setup. "tsql servername" and "isql servername" may use
different servers and even different copies of FreeTDS.

No, the reply you quoted showed column headers only, no data.

Your freetds.conf and odbc.ini look correct to me.  I think isql is
swallowing an error from the server.  I would try the same query using
bsqldb using TDSDUMP viz:

        $ TDSDUMP=stdout bsqldb -S txeis -U dba -P sql

HTH.
