> Currently, Spark does not resolve star expressions in subqueries correctly. It can only resolve the star expressions using the inner query attributes. For example:
> {{CREATE VIEW t(a) AS VALUES (1), (2);}}
> {{SELECT * FROM t WHERE a in (SELECT t.*)}}
> {{SELECT * FROM t, LATERAL (SELECT t.*)}}
> {{org.apache.spark.sql.AnalysisException: cannot resolve 't.*' given input columns '';}}
> Instead, we should try to resolve star expressions in subquery first using the inner attributes and then using the outer query attributes.
