Wenchen Fan updated SPARK-46526:
--------------------------------
Parent: SPARK-35553
Issue Type: Sub-task (was: Bug)
> Limit over certain correlated subqueries results in Nosuchelement exception
> ---------------------------------------------------------------------------
>
> Key: SPARK-46526
> URL: https://issues.apache.org/jira/browse/SPARK-46526
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: Andrey Gubichev
> Assignee: Andrey Gubichev
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0
>
>
> The types of queries that result in errors are:
> * have LIMIT in the subquery
> * predicate with correlated references does not depend on the inner query
> (references exclusively outer table).
> For example:
> {code:java}
> SELECT COUNT(DISTINCT(t1a))
> FROM t1
> WHERE t1d IN (SELECT t2d
> FROM t2
> WHERE t1a IS NOT NULL
> LIMIT 10);
> {code}
> Here, WHERE t1a IS NOT NULL can be conceptually lifted to the join that
> connects inner and outer query.
> Currently, this query results in an error ("no such element exception").
