kangkaisen commented on issue #1356: Wrong query result with constant URL: https://github.com/apache/incubator-doris/issues/1356#issuecomment-504405059 why the poi_second_city_id IN (-1) predicate is used to prune partition? 1 poi_second_city_id IN (-1) is -1 in (-1) 2 In `SingleNodePlanner`, List<Expr> conjuncts = analyzer.getUnassignedConjuncts(scanNode), conjuncts will contain -1 in (-1); 3 In `PartitionColumnFilter keyFilter = createPartitionFilter(slotDesc, conjuncts);` -1 in (-1) will set setInPredicate `partitionColumnFilter.setInPredicate(inPredicate);` 4 So the `RangePartitionPruner.partitionColumnFilters` will contain -1 in (-1) inPredicate. I think the root cause is -1 in (-1) shouldn't be contained analyzer.getUnassignedConjuncts(scanNode). So I think simplify -1 in (-1) to BoolLiteral(true) will fix this issue and reasonable.
