Subject [jira] Commented: (DERBY-2602) TIMESTAMP value is truncated when return to client
Date Tue, 13 Apr 2010 14:10:56 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12856431#action_12856431
] 

Knut Anders Hatlen commented on DERBY-2602:
-------------------------------------------

Thanks for the updated patch, Rick. I think you can get rid of the changes in the Agent classes
by declaring serverSupportsTimestampNanoseconds() as an abstract method in am.Connection.
There's precedence for that, see supportsSessionDataCaching() and serverSupportsLocators().
Then you can access it from am.Cursor via agent_.connection_.

> In ParameterMappingTest   I see the following differences between embedded and client.
 Client is truncating the TIMESTAMP value.  Look for this bug number in the test for reproduction.
