hi,

i have created a user defined aggregate function
function MySum.

now, how can i access the intermediate results
computed by the query evaluator.

for example, if a table has 10000 tuples over which
the sum is calculated, i would like to get the
intermediate value, when only 50 or 100 tuples have
been procesed.  or say, the intermediate results
calculated after every 1ms.

john
