I think it would be best to construct the window separately ( createWindow ) and add a windowFunction(String name, Class<T> type, JpaWindow window, Expression<?>... args) , which also allows reuse of the window. For ordered set-aggregate functions, we should add a functionWithinGroup(String name, Class<T> type, Order order, Expression<?>... args). Also, add a variant that allows passing the filter clause predicate. It would be nice to add some convenience methods for certain functions * ordered set-aggregate functions: listagg , mode , percentile_cont , percentile_disc * window functions: row_number , first_value , last_value , nth_value , dense_rank , rank , percent_rank , cume_dist ( https://hibernate.atlassian.net/browse/HHH-15654#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-15654#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
