Now for the hard part. We now have to execute a loop. On each pass of the loop we are looking for all items whose dependencies have all been sequenced. We will do this over and over until the command is not affecting any rows. It is important that we cannot exit the loop by testing if all rows are sequenced, because a circular dependency will prevent this from happening and we will have an infinite loop.
Theoretically here to serve as a Google magnet so people can find me, though this also serves as a place for me to gather interesting things I mean to work on later when I find time. It is undistinguished in any meaningful way from the trillions of navel-gazing blogs out there and I am in no way recommending you actually read it.My public github projects, sorrowfully waylaid by always more-pressing matters...
