I'm trying to execute the following equivalent sql expression with
cayenne V2.0.3
select * from appointments where status < 2 and group_id = 2 and
date(dt_appointment) = '20070724'
where the intent is to select all appointments where the date matches
the provided date string. The underlying database is MySQL and the
expression above provides the correct results when directly executed.
The corresponding Appointments object contains columns named groupId
(integer), status (integer) and dtAppointment (datetime)
This is what I've coded...
Date item = Calendar.getTime();
String anExp = "groupId = " + identity +
" and status < 2" +
" and date(dtAppointment) = '" +
new
SimpleDateFormat("yyyyMMdd").format(item.getTime()) + "'";
Expression exp = Expression.fromString(anExp);
SelectQuery qAppointments = new SelectQuery(Appointments.class, exp);
List appointments = dc.performQuery(qAppointments, true);
However I am getting the following error...
Exception in thread "Thread-55"

What am I doing wrong in my expression builder?
Thanks,
