ulysses you updated SPARK-33131:
--------------------------------
Description:
Grouping sets construct new aggregate lost the qualified name of grouping
expression. 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}
was:
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}
> Fix grouping sets with having clause can not resolve qualified col name
