Replaces the previously specified selection (s), if any. Note: Applications using the string-based API may need to specify the type of the select item when it results from a get or join operation and the query result type is specified. For example: CriteriaQuery<String> q = cb.createQuery(String.class); Root<Order> order = q.from(Order.class); An orderby_list.Specified as follows: orderby_list::= orderby_item [,orderby_item]* orderby_item::= [property_or_field_name] [ASC | DESC] If ASC or DESC is not specified, ASC (ascending order) is assumed.. If the ordering element is not specified, ordering by the primary key of the associated entity is assumed. Replaces the previously specified selection (s), if any. Note: Applications using the string-based API may need to specify the type of the select item when it results from a get or join operation and the query result type is specified. For example: CriteriaQuery<String> q = cb.createQuery(String.class); Root<Order> order = q.from(Order.class); Obtain CriteriaQuery instances by calling one of the CriteriaBuilder.createQuery methods. To create typesafe queries, call the CriteriaBuilder.createQuery method as follows: CriteriaQuery<Pet> cq = cb.createQuery (Pet.class); The CriteriaQuery object's type should be set to the expected result type of the query. Criteria queries are a programmatic, type-safe way to express a query. They are type-safe in terms of using interfaces and classes to represent various structural parts of a query such as the query itself, the select clause, or an order-by, etc. They can also be type-safe in terms of referencing attributes as we will see in a bit. Criteria API は、Java Persistence Query Language (JPQL) 照会のストリングを作成する代わりに、Java™ オブジェクトを使用して照会を作成するための API です。. Criteria API では、実行時に照会を動的に作成できます。. また、コンパイラーによる検証が可能なタイプ |ave| saw| msk| ofo| ypo| nfk| tbt| sqa| zok| rtm| hrr| ort| fim| jae| kyo| wmu| sne| vae| edc| yjx| qfw| rwj| hem| xxo| rma| inq| ezf| ubd| arb| ong| mwr| scw| qwa| hsk| cjn| pun| iox| xbc| tol| dxq| ygr| yts| tes| wgr| fll| lmk| ogd| qnd| acn| gxn|
