> The method `ResolveAggregateFunctions.resolveFilterCondInAggregate` aims to do the two things
> 1. resolve the expression in having.
> 2. push the having extra agg expression to `Aggregate`
> However we only care about 2 now. If having clause resolution is successful but not exists extra agg expression, we will ignore the resolution. Here is a example:
> {code:java}
> -- Works resolved by ResolveReferences
> select c1 from values (1) as t1(c1) group by grouping sets(t1.c1) having c1 = 1
> -- Works because of the extra expression c1
> select c1 as c2 from values (1) as t1(c1) group by grouping sets(t1.c1) having t1.c1 = 1
> -- Failed
> select c1 from values (1) as t1(c1) group by grouping sets(t1.c1) having t1.c1 = 1{code}
