Subject [jira] [Resolved] (CASSANDRA-4854) Can not select the "Schema" table
Date Wed, 24 Oct 2012 17:00:13 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-4854?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sylvain Lebresne resolved CASSANDRA-4854.
-----------------------------------------

    Resolution: Not A Problem

"Schema" is the old-style, pre-1.1 schema table so as soon as you've correctly started a 1.1
it is expected to be empty. So
{noformat}
select * from "Schema"
{noformat}
is correct and is working as expected.

The new-style schema tables are: schema_keyspaces, schema_columnfamilies and schema_columns.
