Description
"SELECT ID FROM FOO WHERE ID NOT IN (SELECT 1 AS ID FROM FOO)" throws duplicated field 'null'.
Here is logical plan from Calcite.
LogicalFilter(condition=[NOT(CASE(=($3, 0), false, IS NOT NULL($7), true, IS NULL($5), null, <($4, $3), null, false))]): rowcount = 1.0, cumulative cost = {10.375 rows, 16.0 cpu, 0.0 io}, id = 24 LogicalJoin(condition=[=($5, $6)], joinType=[left]): rowcount = 1.0, cumulative cost = {9.375 rows, 15.0 cpu, 0.0 io}, id = 23 LogicalProject($f0=[$0], $f1=[$1], $f2=[$2], $f3=[$3], $f4=[$4], $f5=[$0]): rowcount = 1.0, cumulative cost = {5.25 rows, 11.0 cpu, 0.0 io}, id = 18 LogicalJoin(condition=[true], joinType=[inner]): rowcount = 1.0, cumulative cost = {4.25 rows, 5.0 cpu, 0.0 io}, id = 17 EnumerableTableScan(table=[[FOO]]): rowcount = 1.0, cumulative cost = {0.0 rows, 1.0 cpu, 0.0 io}, id = 12 LogicalAggregate(group=[{}], agg#0=[COUNT()], agg#1=[COUNT($0)]): rowcount = 1.0, cumulative cost = {3.25 rows, 4.0 cpu, 0.0 io}, id = 16 LogicalProject($f0=[$0], $f1=[true]): rowcount = 1.0, cumulative cost = {2.0 rows, 4.0 cpu, 0.0 io}, id = 15 LogicalProject(ID=[1]): rowcount = 1.0, cumulative cost = {1.0 rows, 2.0 cpu, 0.0 io}, id = 14 EnumerableTableScan(table=[[FOO]]): rowcount = 1.0, cumulative cost = {0.0 rows, 1.0 cpu, 0.0 io}, id = 13 LogicalAggregate(group=[{0}], agg#0=[MIN($1)]): rowcount = 1.0, cumulative cost = {3.125 rows, 4.0 cpu, 0.0 io}, id = 22 LogicalProject($f0=[$0], $f1=[true]): rowcount = 1.0, cumulative cost = {2.0 rows, 4.0 cpu, 0.0 io}, id = 21 LogicalProject(ID=[1]): rowcount = 1.0, cumulative cost = {1.0 rows, 2.0 cpu, 0.0 io}, id = 20 EnumerableTableScan(table=[[FOO]]): rowcount = 1.0, cumulative cost = {0.0 rows, 1.0 cpu, 0.0 io}, id = 19
In this case AggregateCall.name could be null, so there could be duplicated fields in trident tuple which are having 'null' as name.
We should refer the RowType of LogicalAggregate, but another issue is that its name could be same as upstream's output field name, so it makes another duplication.
One way to resolve this is assigning temporal field names while aggregating, and finally replace them with fields name in RowType of LocalAggregate.
We can achieve this easier when STORM-2072 will be merged.
