This or more general approach supported by SQLTemplate - "#bind" directive
(User Guide, chapter 7.7.3 -
http://objectstyle.org/cayenne/userguide/fetch/sqltemplate-scripting.html).
Using #bind($date) or #bind($date 'DATE') will delegate date formatting
task to the underlying Oracle JDBC driver. And you can contol how the date
is treated (i.e. date, timestamp, etc.)
