I appreciate the video. You did a good job of explaining everything. Maybe next time go through how it works within the code of the recursion kind of like debugging mode so we can see how the process works within the sql code.

Maybe I'm being a bit slow, but the bit I'd still like to understand is why Fuller is returned to the result set when his 'ReportsTo' is null and the same field is linking the recursion via an inner join.

don't worry, I've just seen it.... Level one is returned in the first union....
