Apache Spark reassigned SPARK-38155:
------------------------------------

    Assignee:     (was: Apache Spark)

> Disallow distinct aggregate in lateral subqueries with unsupported correlated 
> predicates
> ----------------------------------------------------------------------------------------
>
>                 Key: SPARK-38155
>                 URL: https://issues.apache.org/jira/browse/SPARK-38155
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL
>    Affects Versions: 3.3.0
>            Reporter: Allison Wang
>            Priority: Major
>
> Block lateral subqueries in CheckAnalysis that contain DISTINCT aggregate and 
> correlated non-equality predicates. This can lead to incorrect results as 
> DISTINCT will be rewritten as Aggregate during the optimization phase.
> For example
> {code:java}
> CREATE VIEW t1(c1, c2) AS VALUES (0, 1)
> CREATE VIEW t2(c1, c2) AS VALUES (1, 2), (2, 2)
> SELECT * FROM t1 JOIN LATERAL (SELECT DISTINCT c2 FROM t2 WHERE c1 > t1.c1)
> {code}
> The correct results should be (0, 1, 2) but currently, it gives  be[(0, 1, 
> 2), (0, 1, 2)].
