If I am executing a select query via isc_dsql_execute in a background
thread under Windows, what is the best way to abort the execution if
the user cancels the operation in a foreground thread? Can I issue a
rollback on the transaction? Do I just orphan the execution thread
until it completes? Or is there some other mechanism?

TIA,
