Example which works:
select tb from TransportBooking as tb and TIMESTAMP(tb.bookingDate, tb.bookingTime) >= current_timestamp() order by tb.bookingDate Example which does not work:
select tb from TransportBooking as tb and TIMESTAMP(tb.bookingDate, tb.bookingTime) >= current_timestamp() order by :order

Hibernate Named Query helps us in grouping queries at a central location rather than letting them scattered all over the code. Hibernate Named Query syntax is checked when the hibernate session factory is created, thus making the application fail fast in case of any error in the named queries.
The Order class has two methods to set the sorting order: asc(String attribute) : Sorts the query by attribute in ascending order. desc(String attribute) : Sorts the query by attribute in descending order.
You call the createNamedQuery method on the EntityManager with the name of the named query you want to execute. That gives you an instance of a Query or TypedQuery interface. You then call the setParameter method on the returned interface for each bind parameter used in your query.
Not supported, input parameters are only allowed in the WHERE and HAVING clauses and you cannot use parameters for the ORDER BY clause. Or if I rephrase, you can't use parameters for columns, only values. So, either:
