[jira] [Commented] (SPARK-29630) Not allowed to create a permanent
view by referencing a temporary view in EXISTS
[ https://issues.apache.org/jira/browse/SPARK-29630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16961765#comment-16961765 ]
Aman Omer commented on SPARK-29630:
-----------------------------------
[~maropu] I think when we project some constant in subquery, Spark will not link subquery's table/view. Hence table _v8_temp_ is not dependent on _temp_table_.
Please check the output for following query.
$ CREATE VIEW v8_temp AS SELECT * FROM base_table WHERE EXISTS (SELECT * FROM temp_table);
