Davies Liu commented on SPARK-14781: ------------------------------------ PR 12720 is pretty close, we should wait for that. > Support subquery in nested predicates > ------------------------------------- > > Key: SPARK-14781 > URL: https://issues.apache.org/jira/browse/SPARK-14781 > Project: Spark > Issue Type: New Feature > Components: SQL > Reporter: Davies Liu > > Right now, we does not support nested IN/EXISTS subquery, for example > EXISTS( x1) OR EXISTS( x2) > In order to do that, we could use an internal-only join type SemiPlus, which > will output every row from left, plus additional column as the result of join > condition. Then we could replace the EXISTS() or IN() by the result column. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
