Subject [jira] [Commented] (HIVE-1977) DESCRIBE TABLE syntax doesn't support specifying a database qualified table name
Date Sat, 02 Aug 2014 21:20:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1977?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14083734#comment-14083734
] 

Lefty Leverenz commented on HIVE-1977:
--------------------------------------

This could be documented in the wiki, but [~thejas] recommended leaving it undocumented:

Yes, DOT is also optional now, but I am not a fan of that syntax. It has
made it almost impossible
to extend describe statements to other commands, as you can see from
HIVE-5931<https://issues.apache.org/jira/browse/HIVE-5931?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13924779#comment-13924779>
.
Lets just document the syntax with DOT for now. That way it be easier to
fix the syntax later if we choose to.

So if I get agreement here, I'll remove the TODOC10 label from this JIRA ticket.

> The syntax for DESCRIBE is broken. It should be:
> {code}
> DESCRIBE [EXTENDED] [database DOT]table [column]
> {code}
> but is actually
> {code}
> DESCRIBE [EXTENDED] table[DOT col_name]
> {code}
