Re: idea to have driver return immediately after a query

For what it's worth, you don't even need to ask for 1 row. At Truviso,
we have a layer on top of the driver that asks for 0 rows initially,
and this works fine (in terms of providing query metadata). There
*may* be some plans with significant startup overhead where the cost
of returning zero rows is much less than that of returning one row.

Thanks,
