Description:
This query does work in Spark SQL:
{noformat}
select (with cte(x) as (select 1) select x from cte) from test10
{noformat}
But the following query can't handle the outer reference to the {{c}} column of
{{test10}} table:
{noformat}
select (with cte(x) as (select c) select x from cte) from test10
org.apache.spark.sql.AnalysisException: Expressions referencing the outer query
are not supported outside of WHERE/HAVING clauses:
Project [outer(c#41)]
+- OneRowRelation
;;
