Getting resuls asynchronous from SQL Server

Hi,
Suppose I have following T-SQL statements :
INSERT #T SELECT ... -- takes c. 10 minutes
SELECT * FROM #T
-- Calculation in cycle over #T
-- on end of cycle will be inserted new row to #NextTable
-- end of cycle
SELECT * FROM #NextTable;
All this I run as batch.
Can I get results SQL when batch is still running but
SELECT * FROM #T
is already executed ?
And after finishing batch SQL will return only rest of results ?
Something like IIS (Internet Information Server) when returns big page to
client. It starts return page while page is still executing.
I don't want to divide this batch to multiple queries because then I would
must pass several megabytes to and from these queries multiple times. So if
it is in single batch I reduce roundtrips of data over 100 MB from SQL serev

when SQL server process statement and not whole batch.

Yes, you can use the FAST x query hint hto have SQL Server generate the
first X rows in the result set as quickly as possible at the expense of
full query optimization.
Select col1
From TableA OPTION (FAST 100)
But asynchronous execution is the domain of the client library and not
SQL Server. .Net does not include async calls (if I'm not mistaken). If
you're using ADO, you can issue an async execute and you should be able
to get results back faster.\
I've never tested the FAST option myself.
