[hibernate-issues] [JIRA] (HHH-16815) add methods to SelectionQuery to add order by items

Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16815 ( https://hibernate.atlassian.net/browse/HHH-16815?atlOrigin=eyJpIjoiYzMzNz... ) Re: add methods to SelectionQuery to add order by items ( https://hibernate.atlassian.net/browse/HHH-16815?atlOrigin=eyJpIjoiYzMzNz... ) For those who weren’t in love with putting ascending() and descending() directly on Query , and wanted a separate object representing a sort order which can be passed around, how about the following “compromise” API which has nice features of both options: * Introduce an Order object which is some sort of linked list. * Add only Query.setOrder(Order)}}to {{Query. The most naive usage would look like: session.createSelectionQuery( "from Book" ) .setOrder(Order.asc(Book_.title).desc(Book_.isbn)) .getResultList(); Or, for sorting by column index: session.createSelectionQuery( "select isbn, title from Book" ) .setOrder(Order.asc(0).desc(1)) .getResultList(); The Order API itself could be quite flexible, accommodating stuff like: session.createSelectionQuery( "from Book" ) .setOrder(Order.by(Book_.title, SortOrder.ASCENDING).by(Book_.isbn, SortOrder.DESCENDING)) .getResultList(); along with other stuff we haven’t even thought of yet. Thus, Order would occupy a very similar role in the architecture that EntityGraph occupies for fetching.
