[teiid-issues] [JBoss JIRA] (TEIID-4796) Support automatic pushdown of unsupported functions in JDBC connectors.

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13371815#comment-13371815 ] 

Steven Hawkins commented on TEIID-4796:
---------------------------------------

Unfortunately this is more complicated than it seems.  We need to be able to resolve the function to at least know the return type.  

It's very straight-forward to add a source function to a source model.  

Also depending upon the source the function may be listed by the DatabaseMetadata.getFunctions.  It would be easier to enhance the importer to import functions from there.
