Comment (by shaib):
The first comment is not clear to me: It may refer to
{{{
cast (coalesce (field, now) as datetime)
}}}
or to
{{{
coalesce (field, cast (now as datetime))
}}}
The latter may be done completely automatically by Django, the former may
also be done automatically if an output field is provided.
Also note https://dev.mysql.com/doc/refman/5.6/en/date-and-time-
literals.html -- before 5.6.4 !MySql understood date literals as strings,
not sure how that applies to embedded variables; please try to re-test
this with a later-than-5.6.4 version.
