------------------------------------
Summary: Unify the logic to handle COUNT bug for scalar and
lateral subqueries
Key: SPARK-36113
URL: https://issues.apache.org/jira/browse/SPARK-36113
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.2.0
Reporter: Allison Wang
Currently, for scalar subqueries, the logic to handle the count bug is in
`RewriteCorrelatedScalarSubquery` (constructLeftJoins) while lateral subqueries
rely on `DecorrelateInnerQuery` to handle the COUNT bug.
We should unify them without introducing additional left outer joins for scalar
subqueries.
