hmmm, You must assume a programmer's perspective. Not a user's.
The program must do what the user says not viceversa.
The terms of the problem are: given a set of tables and relationships
and given a set of fields, possibly equipped with aggregate function,
which result in the report, determine the correct split of
relationships and the subqueries that will yield the desired result.
You can see an implementation of that, for instance, in Business
Objects (the well know BI program) [I believe that implementation fails
under some conditions]
For instance in my example the first query is a wrong result. Report
computation is actually wrong. The second query (a UNION of 2
