Hi Tom,

Unfortunately I can't have pure SQL output in my org files for two reasons:

1. The result set I am dealing with for this particular problem is about
20000 records
2. My SQL server (Netezza, "big data appliance") is not supported by
Babel-SQL. I configured sql-mode to work with Netezza but session-based SQL
is not supported by Babel either. I started adding support for SQL sessions
to ob-sql.el and it kind of works but the results I am getting are
inconsistent and only a small subset of header parameters is supported. Of
course I haven't tested is with any other database. I can share what I've
done if anybody is interested.

Regards,
Alex
