------------------------------------

             Summary: Support ANY subquery
                 Key: SPARK-26854
                 URL: https://issues.apache.org/jira/browse/SPARK-26854
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Mingcong Han


ANY syntax
{quote}
SELECT column(s)
FROM table
WHERE column(s) operator ANY
    (SELECT column(s) FROM table WHERE condition);
{quote}
`ANY` subquery can be regarded as a generalization of `IN` subquery. And `IN` subquery is a special case of `ANY` subquery whose operator should be "=". The expression evaluates to `true` if the comparison between `column(s)` and any row in the subquery's result set returns `true`.
