Hi All,
I am using a Hibernate named sql query in my app, which contains a
clause "where deliverydate between :startdate and :enddate".
In my java code, I'm loading this into an org.hibernate.Query object and
then setting the parameter values like this:
Query query = session.getNamedQuery("delivery.date.range");
query.setParameter("startdate", startDate);
query.setParameter("enddate", endDate);
return query.list();
When I executed this code, I got the following error:
JDBCExceptionReporter.logExceptions | Error: operator does not exist
date >= bytea
I had the feeling I should be specifying a type for my query parameters
(the setParameter method has a third parameter that is an
org.hibernate.Type type), but I couldn't find a value that seemed
suitable for a Joda LocalDate object.
In the end, I supplied my date values as java.util.Date types like this:
query.setParameter("startdate", startDate.toDateAtStartOfDay().toDate());
and that allows my tests to pass. However, I kind of expected the
joda-hibernate package to have some classes that implement the
org.hibernate.type
(http://www.hibernate.org/hib_docs/v3/api/org/hibernate/type/Type.html)
interface that could be used in query parameters.
Has anyone else used joda date and/or time values in Hibernate named
queries? Can you provide any tips for new players?
TIA,
