| we are trying to execute a remote sql query from one sql server against
another. Both servers are in the same domain. The query is a simple select
* from tablename where surname = whatever. We precede this with an
'opendatasource' statement. The query returns only a few rows. When we run
the query between two sql servers on the same lan segment the query runs in a
second or two. When we run the query between servers on two different
network segments (seperated by a firewall) but still both in the same domain
the same query takes 50+ seconds to run. Looking further, it seems that the
query is actually being executed on the local server so the entire table
(over 1 million rows) is copied locally before running the query. How can I
run the query as a remote query so that the entire query is run on the remote
sql server and only the query results are passed accross the network to the
local server? I have also tried creating a linked server and using OPENQUERY
but still takes ages to run.
Thanks
