> Teiid has already applied a fix to support the JDBC spec change for when an alias is used in the select clause. The spec change says the "AS" name will now be returned when getColumnLabel() is called, instead of getColumnName(). Unfortunately, this breaks backwards compatibility. To resolve the issue, the JDBC driver, to provide support for backwards compatibility, can allow the user to specify the useJDBC4ColumnNameAndLabelSemantics=true (default is false) property on the url (this is the recommended spec property).

> Currently, in order to use a database function, even if pushdown is required, it is still necessary to add the function interface to a Java class within the connector, and the connector then must be deployed to the server in order to allow for this pushdown function to be used within the Designer. This creates a lot of extra effort every time you want to make use of a new database function. Particularly, given the schema designer doesn't necessarily have access to either the connector code or the server, and then must involve other parties simply to be able to use an additional database function. It would be very beneficial to speedy schema development if that was not necessary, and if, say, the interface could be defined on the Designer side, added to the VDB, and then deployed as part of the VDB.
