java - JPA: NamedQuery parameter in query string for switches -


i wondered how in jpa if want call namedquery stored in entity different settings example order desc or asc use in way parameters (setparameter()). example not working:

@namedquery(name = "entry.findall", query = "select e entry e e.switch = :switch order e.name :order)

is way use 2 queries like:

@namedquery(name = "entry.findalldesc", query = "select e entry e e.switch = :switch order e.name desc) @namedquery(name = "entry.findallasc", query = "select e entry e e.switch = :switch order e.name asc)

or generate query string in code?

i wondered found no way, because in queries have change such things , make programming style prefer use central namedqueries stored in entities impossible.

namedquery static query. can't put dynamic query value (i.e asc or desc) in namedquery. should use dynamicquery(i.e. jpql) or native query or criteria desired output.
