<li> The "[select-stmt]"
     must be a [compound select] where the right-most [compound-operator] is
     either UNION or UNION ALL.
<li> The table named on the left-hand side of the AS keyword must appear
     exactly once in the FROM clause of the right-most SELECT statement
     of the compound select, and nowhere else.


</ol>

<p>To put it another way, a recursive common table expression must
look like the following:
