Description:
Current {{Substitution#getRexShuttle}} does not take {{RexLiteral}} into
consideration.
Thus below query & mv fails matching:
{code:java}
MV:
select deptno, sum(salary), sum(commission), sum(k)
from
(select deptno, salary, commission, 100 as k
from emps)
group by deptno
Query:
select deptno, sum(salary), sum(k)
from
(select deptno, salary, 100 as k
from emps)
group by deptno
{code}
The root cause is that {{ProjectToProjectUnifyRule}} compensates a {{Project}}
which contains {{RexLiteral}}, but {{AggregateOnProjectToAggregateUnifyRule}}
works only when the {{Project}} in query is a mapping
