Subject [jira] Commented: (DERBY-4550) Using ij to copy data from one DB to an other
Date Tue, 16 Feb 2010 18:53:27 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12834381#action_12834381

Rick Hillegas commented on DERBY-4550:
--------------------------------------

Hi Sylvain,

I think that we should allow your second example:

ij> set connection fred_conn;
ij> prepare fred_conn.second_select as 'select * from t1';

There ought to be a name-resolution phase in ij (or at least identifier-resolution). A connection-qualified
identifier could be allowed in this situation provided that the connection is the current
connection.

Thanks,
-Rick

> It is possible to have open connections to several databases while running ij, but it
is not currently possible to copy data from one DB to an other one.
> Not only such a feature would allow to copy data between Derby databases. But, ij being
mostly DB agnostic, if will ease import/export from any JDBC compliant data source.
