Subject [jira] Commented: (HIVE-701) lots of reserved keywords in hive
Date Tue, 28 Jul 2009 22:13:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12736332#action_12736332

Ashish Thusoo commented on HIVE-701:
------------------------------------

This came up on show table status. It so happens as you pointed out that status is being used
for column names and if we put it into a keyword now, it will break existing scripts. Any
ideas on how to address this? I think this is going to be tricky with antlr.

> There is a problem if we want to use some reserved keywords:
> for example, creating a function of name left/right ? left/right is already a reserved
keyword.
> The other way around should also be possible - if we want to add a 'show tables status'
and some applications already use status as a column name, they should not break
