Subject [jira] [Commented] (FLINK-5441) Directly allow SQL queries on a Table
Date Thu, 02 Mar 2017 16:50:45 GMT

    [ https://issues.apache.org/jira/browse/FLINK-5441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15892592#comment-15892592

ASF GitHub Bot commented on FLINK-5441:

Github user twalthr commented on the issue:

    I think the point is that we don't know if the table will ever be used again. If we unregister
them after optimization, we can not have multiple `toDataStream()` calls for one table.

> Right now a user has to register a table before it can be used in SQL queries. In order
to allow more fluent programming we propose calling SQL directly on a table. An underscore
can be used to reference the current table:
> {code}
> myTable.sql("SELECT a, b, c FROM _ WHERE d = 12")
> {code}
