[Tommi Vd]

Hi i have a problem when i want to get some date out of my oracle database:

The table is empty but normally that may not be the cause, this is the error:

Caused by: java.sql.SQLException: ORA-00932: inconsistent datatypes: expected DATE got BINARY

This is the code that queries the database:

    
Date now = DateUtil.now();
		Query qry = getSession().createQuery("from VehicleAssignment where user = ? and (toDate <= ? or toDate = ?)");
		qry.setParameter(0, user);
		qry.setParameter(1, now);
		qry.setParameter(2, null);
		try{
			return (List<VehicleAssignment>) qry.list();
		}catch(Exception ex){
			ex.printStackTrace();
		}
		return null;

In my database there is a from date and a to date, both are stored as dates in the database...
the now Date is java.util

Anyone who has an idea?

regards,

Kwast

change "date = ?" to "date is null" and remove the extra parameter.
