Subject [jira] Commented: (HIVE-1517) ability to select across a database
Date Fri, 18 Feb 2011 23:01:38 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12996641#comment-12996641
] 

John Sichi commented on HIVE-1517:
----------------------------------

Hey Siying,

This case from my original comment way at the top of this JIRA issue is not handled by your
patch.

{noformat}
create database db1;
use db1;
create table t(i int);

create view v as select * from t;

create database db2;
use db2;
select * from db1.v;
{noformat}

This will take some work in the unparse when we store the view definition.
