Freddy,

Its the data returned by a server when a "compute" clause is present on a
query.

You may not know (as I didn't ) that you can specify a compute clause like
this :

USE pubs

SELECT type, price, advance
FROM titles
ORDER BY type
COMPUTE SUM(price), SUM(advance) BY type

On the wire the server sends back some extra "results" messages , describing
the computed data, and extra "row" messages, containing the computed data.
We currently don't handle this data very well.
