Subject [jira] Updated: (DERBY-2487) Enhance Derby with EXPLAIN Functionality
Date Tue, 07 Apr 2009 02:38:13 GMT

     [ https://issues.apache.org/jira/browse/DERBY-2487?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bryan Pendleton updated DERBY-2487:
-----------------------------------

    Attachment: userSchemaPrototyping.diff

I made some good progress on 'userSchemaPrototyping.diff' and wanted to update it again.

It now passes many of the tests, which is very cool!

I am having a bit of problems with jdbc:default:connection, I'll post
a message to derby-dev trying to explain the problem and ask for help.

than they`re getting with the current RuntimeStatistics facility. This extension is based
