------------------------------------
Summary: subqueries always must be aggregated before
Key: SPARK-28553
URL: https://issues.apache.org/jira/browse/SPARK-28553
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.0.0
Reporter: Dylan Guedes
Looks like Spark subqueries does not work well with variables and values from
outside of subquery. For instance, this query work on PgSQL:
{code:sql}
-- SELECT lead(ten, (SELECT two FROM tenk1 WHERE s.unique2 = unique2)) OVER
(PARTITION BY four ORDER BY ten)
-- FROM tenk1 s WHERE unique2 < 10;{code}
However, it does not work in Spark.
