[
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2647?page=c...
]
Dennis Fleurbaaij commented on HHH-2647:
----------------------------------------
Just some code to get you started.
@Entity
public Class Entity
{
private Date dateTime;
}
With the following HQL code:
FROM Entity
WHERE
( ( entity.dateTime is null AND entity.toDateTime < :dateTime)
OR
( entity.dateTime >= :dateTime AND entity.toDateTime is null )
OR
( entity.dateTime >= :dateTime AND entity.toDateTime < :dateTime )
)

will be balanced to:
