In order to get the fetch stats, you have to fetch the records, so it
is a bit of a nonsense to consider the fetch statistics of a query
without retrieving the data. Of course we are often interested in the
execution time rather than the fetch time when checking plans, so I
use FIRST 1 (which doesn't tend to modify the plan) until I am
satisfied, then check it again without the FIRST 1 constraint.

Perhaps you could rather send the output to a file than the screen?

try iSQL -o

or piping the output to a file through your OS provided mechanism.
