// doing this with execute_sql rather than set_field and friends because of
// adodb retardedly trying to make "order"+1 and friends into a string
// I couldn't find a way to shift a bunch of rows in step even with set constraints deferred.
// the two options I found were to move them all out of range (eg start at max +1) and then back again
// or move them into negative and back into positive (Grant's suggestion) which I like more.
* We need to use execute_sql here because ADODB naturally
* wants to convert "order+1" into string fields.
* Additionally, we need to move a set of rows in step, and
* sign-switching is one way to do that without violating constraints.
