one more thing that i assume must work this way, but you don't seem to have documented, is how to test for exceptions. i guess SQL_Exception (a return value, right?) is false when there's no error?
related: do you have any examples that include all the error handling that would be necessary in a real app? how do you display the exception details (it seems to be an opaque type) to the user? perhaps i am missing something here (can't even find exception in the clickable API image)?
(wish i had known about this a few months ago as it would have saved me some work - thanks).
