criteria-api

I have 2 classes mapped with db Tables. Composite Primary Key Class : @Embeddable public class Pk implements Serializable, Cloneable { @Column(name = "dataId") private String dataId; @Column(name = "occurrenceTime") private Timestamp occurrenceTime; public String getDataId() { return dataId; } public Pk setDataId(String dataId) { this.dataId = dataId; return this; } public Timestamp getOccurrenceTime() { return occurrenceTime; } public Pk setOccurrenceTime(Timestamp occurrenceTime) { this.occurrenceTime = occurrenceTime; return this; } @Override public boolean equals(Object o) { if (this == o)

I have document structure like this - { "_id" : "11223344", "orderId" : "00001041", "key" : "56h68ab4c876dbe1cd0b1ee" "status" : [ { "updatedTimeStamp" : ISODate("2017-06-01T16:05:42.737Z"), "orderStatus" : "INITIATED" }, { "updatedTimeStamp" : ISODate("2017-06-01T16:05:42.737Z"), "orderStatus" : "CONFIRM_PAYMENT" }, { "updatedTimeStamp" : ISODate("2017-06-01T16:07:36.797Z"), "orderStatus" : "RESTAURENT_CONFIRMATION_PENDING" }, { "updatedTimeStamp" : ISODate("2017-06-01T16:20:36.798Z"), "orderStatus" : "ORDER_CONFIRMED" }, { "updatedTimeStamp" : ISODate("2017-06-01T16:51:27.562Z"),

The current code: CriteriaQuery criteriaQuery = cb.createQuery(MinutisPreke.class); Root<MinutisPreke> from = criteriaQuery.from(MinutisPreke.class); Join<LankomumasDiena, MinutisPreke> ld = from.join("lankomumasDiena", JoinType.LEFT); cb.and(cb.equal(ld.get("intervalas"), 7)); generates the following query: SELECT COUNT(t0.pr_id) FROM preke AS t0 LEFT OUTER JOIN lankomumas AS t1 ON (t1.pr_id = t0.pr_id) WHERE (t1.intervalas = 7) How to add statement in the LEFT OUTER JOIN ON clause using criteria query so my code would generate this query: SELECT COUNT(t0.pr_id) FROM preke AS t0 LEFT OUTER

I'm using JPA 2.0 in EclipseLink 2.3.2 in which I have a many-to-many relationship between products and their colours. A product can have many colours and a colour can be associated with many products. This relationship is expressed in the database by three tables. product prod_colour (join table) colour The prod_colour table has two reference columns prod_id and colour_id from its related parent tables product and colour respectively. As obvious, the entity class Product has a set of colours - java.util.Set<Colour> which is named colourSet . The entity class Colour has a set of products -

Is the criteria api of eclipselink jpa2 supported for java se 6 projects? If not, that's my problem. Do I need to specify anything special to the criteria api in the persistence.xml? This is my criteria query: final EntityType<Meaning> Meaning_ = em.getMetamodel().entity(Meaning.class); final CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Integer> cq = cb.createQuery(Integer.class); final Root<Meaning> meng = cq.from(Meaning.class); cq.where(meng.get(Meaning_.lastPublishedDate)); //this attributes are not recognized/found cq.select(meng.get(Meaning_.objId)); // " " TypedQuery

I'm using jpa and I have the following entity: @Entity @Table(name="favorites_folders") public class FavoritesFolder { private static final long serialVersionUID = 1L; @Id private String id; @NotNull @Size(min = 1, max = 50) public String name; @ElementCollection(fetch = FetchType.LAZY) @CollectionTable( name="favorites_products", joinColumns=@JoinColumn(name="folder_id") ) @Column(name="product_id") @NotNull private Set<String> productsIds = new HashSet<String>(); } What I want to do is to get a set of FavoritesFolder entities that contains the string "favorite-id" in their productsIds member
