Subject [jira] Commented: (HIVE-675) add database/scheme support Hive QL
Date Wed, 09 Sep 2009 17:05:58 GMT

    [ https://issues.apache.org/jira/browse/HIVE-675?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12753166#action_12753166

Prasad Chakka commented on HIVE-675:
------------------------------------

Yes, by default currentDatabase() can be used and since only Hive.java holds the current database
name, it should be fine.

otherwise patch looks good.

> Currently all Hive tables reside in single namespace (default). Hive should support multiple
namespaces (databases or schemas) such that users can create tables in their specific namespaces.
These name spaces can have different warehouse directories (with a default naming scheme)
and possibly different properties.
> There is already some support for this in metastore but Hive query parser should have
this feature as well.
