* The tree below illustrates the canonical plan (plus access nodes). 'y' and
* 'z' are two inline views. Notice each has a SELECT node underneath - the
* criteria represented by each of those SELECT nodes is on the inner side of
* their respective left outer joins (LOJ). So, each criteria needs to be
* migrated to the join criteria.

* / \
* LOJ SRC z
* / \ |
* SRC SRC y SEL
* MedB | |
* SEL ACC
* | |
* ACC SRC SmA

* SRC MedA
* </pre>
* Here's a diagram of what the join plan of the resulting atomic query should
* look like.
