Scenario 1 is entirely dependent upon your RDBMS and your JDBC driver... I don't believe it works in iBATIS 2 either. Most JDBC drivers seem to strip the table prefix from the column name. So unfortunately, column aliases are your only hope there.
If you find a JDBC driver that works differently (either for the column name or label) I'd love to know, just in case there is a flag or something we can use. I'll look into Scenario 2 and respond in the JIRA ticket.
