Affects Version/s: (was: 3.0.0)

> Handling outer links in CTE subquery expressions
> ------------------------------------------------
>
> Key: SPARK-28297
> URL: https://issues.apache.org/jira/browse/SPARK-28297
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Peter Toth
> Priority: Major
>
> 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
> ;;
> Project [scalar-subquery#167 [] AS scalarsubquery()#169]
> : +- Project [x#168]
> : +- SubqueryAlias `cte`
> : +- Project [c#41 AS x#168]
> : +- Project [outer(c#41)]
> : +- OneRowRelation
> +- SubqueryAlias `default`.`test10`
> +- Relation[c#41] parquet
> {noformat}
> where test10:
> {noformat}
> CREATE TABLE test10 (c INTEGER);
> INSERT INTO test10 SELECT generate_sequence(1, 10);
> {noformat}
