Subject [jira] [Commented] (FLINK-22804) "CREATE VIEW" statement loses computed columns, metadata columns, watermark and table constraint
Date Mon, 31 May 2021 02:08:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-22804?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17354176#comment-17354176

Jark Wu commented on FLINK-22804:
---------------------------------

Hi [~yulei0824], I'm afraid view doesn't support this, because view will lose meta information
of table. You can get this information by calling {{desc table}}.
