Yuanjian Li updated SPARK-31663:
--------------------------------
Labels: (was: correct)
> Grouping sets with having clause returns the wrong result
> ---------------------------------------------------------
>
> Key: SPARK-31663
> URL: https://issues.apache.org/jira/browse/SPARK-31663
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.5, 3.0.0
> Reporter: Yuanjian Li
> Priority: Major
>
> Grouping sets with having clause returns the wrong result when the condition
> of having contained conflicting naming. See the below example:
> {quote}
> select sum(a) as b FROM VALUESÂ (1, 10), (2, 20) AS T(a, b) group by GROUPING
> SETS ((b), (a, b)) having b > 10
> {quote}
> The `b` in `having b > 10` should be resolved as `T.b` not `sum(a)`, so the
> right result should be
> {quote}
> +---+
> | b|
> +---+
> | 2|
> | 2|
> +---+
> {quote}
> instead of an empty result.
> The root cause is similar to SPARK-31519, it's caused by we parsed HAVING as
> Filter(..., Agg(...)) and resolved these two parts in different rules. The
> CUBE and ROLLUP have the same issue.
