Subject [jira] Commented: (HIVE-1517) ability to select across a database
Date Thu, 10 Feb 2011 05:58:57 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12992875#comment-12992875
] 

Siying Dong commented on HIVE-1517:
-----------------------------------

Looks like we have some trouble with printing token location in error message. new CommonToken(int,
String) doesn't include location information there, so that the error message will always
be "line 0:-1". Maybe we have to move from this approach to separate tokens for db and tab
name.
