Wang Weidong updated CALCITE-3466:
----------------------------------
Description:
While convert RelNode to SqlNode, the "group by" statement in subquery was
dropped unexpectedly. For example,
original sql is:
{code:sql}
select a, avg(c1) from (select a,sum(d),b as c1 from t_testProjectMerge group
by b,a) as t group by a
{code}
RelNode converted by SqlNode is
{code:txt}
_LogicalAggregate(group=[{0}], EXPR$1=[AVG($1)])
LogicalProject(A=[$1], C1=[$0])
LogicalAggregate(group=[{0, 1}], EXPR$1=[SUM($2)])
LogicalProject(B=[$1], A=[$0], D=[$3])
EnumerableTableScan(table=[[T_TESTPROJECTMERGE]])
{code}
