Hi Richard At the end of discussion, the best bet for something that "approaches" a threaded version of multiple queries would be something like: 1. open connection to database 2. issue query using asynchronous call (mysql and postgresql support this, haven't checked the others) 3. pick up result when ready To get the threaded-ness, just open a connection per query you want to run asynchronous and pick it up when you're ready for it - i.e. iterate over steps 1-2, then do step 3 when things are ready.
