Subject [jira] [Commented] (FLINK-8868) Support Table Function as Table for Stream Sql
Date Tue, 21 Aug 2018 05:26:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-8868?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16586949#comment-16586949
] 

Hequn Cheng commented on FLINK-8868:
------------------------------------

Would it better to write the SQL as: SELECT * FROM TABLE(tf("a")), i.e, remove the Lateral
key word, since Lateral sounds like containing an outer reference?
