[teiid-issues] [JBoss JIRA] Commented: (TEIID-1589) metadata per translator per request

[Mark Addleman (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-1589?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12603532#comment-12603532 ] 

Mark Addleman commented on TEIID-1589:
--------------------------------------

I think it only makes sense to apply this at the column level since multiple translators are potential involved in a single result set.  Further complicating this problem is that multiple translators could be involved on a row basis if we're talking about a UNION statement.  I'm not sure how to address attaching metadata on a row-wise basis but an extension to the ResultSetMetadata interface to handle column-wise metadata would look something like:
   public Serializable getExecutionFactoryMetadata(String columnName);

> I'd like to the translator to attach metadata to the results it passes back to the Teiid JDBC client.  For example, I'd like the translator to examine the connection object and decorate the returned data with which datasource provided the data.
