> Support "ANY" or sub-query for Pivot "IN" clause
> ------------------------------------------------
>
> Key: SPARK-24163
> URL: https://issues.apache.org/jira/browse/SPARK-24163
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.3.0
> Reporter: Wei Xue
> Priority: Major
>
> This is part of a functionality extension to Pivot SQL support as SPARK-24035.
> Currently, only literal values are allowed in Pivot "IN" clause. To support
> ANY or a sub-query in the "IN" clause (the examples of which provided below),
> we need to enable evaluation of a sub-query before/during query analysis time.
> {code:java}
> SELECT * FROM (
> SELECT year, course, earnings FROM courseSales
> )
> PIVOT (
> sum(earnings)
> FOR course IN ANY
> );{code}
> {code:java}
> SELECT * FROM (
> SELECT year, course, earnings FROM courseSales
> )
> PIVOT (
> sum(earnings)
> FOR course IN (
> SELECT course FROM courses
> WHERE region = 'AZ'
> )
> );
> {code}
