Non blocking query on a table in SQL Server 2000

Hi Folks,
How can I invoke a non blocking ODBC query on a table in a SQL Server
database. Our current design requires the method invoking the query to
'return' immediately after invoking the query. The results of the query
should be put in a globally accessible location.
I think SQLFetch is a blocking call.
Thanks,
Vishal

You have to use muliple threads. It is SQL Execute that usually takes
long time, not SQLFetch(). A call to single SQLFetch usually does not
take long unless you have some network connection problem.
Here is what you can do:
From your main application thread spawn a new one that does
SQLExecute(). The same spawned thread will call SQLFetch and put the
result in a shared buffer, possibly a global to you app. Then send a
Window message to you application notifying it that some data has be put
in the buffer. Read this data from your primary thread.
