I have a table in which certain words or word groups are stored. I want to select entries which start with an uppercase letter, cointain no space and contain only letters. My SQL looks like this: select word from words where w_id > 100 AND word REGEXP '^[A-Z][A-Za-z]*$' limit 2000; How do I do the same thing using criteria? user3487063 Try this: List words = session.createCriteria(Word.class) .setProjection(Projections.property("word")) .add(Restrictions.and(Restrictions.gt("w_id",100), Restrictions.sqlRestriction(word REGEXP '^[A-Z][A-Za-z]*$'))) .setMaxResults(2000).list(); 来源： https:/

I have two entities: public class Photo { Long id; String url; @ManyToOne @JoinColumn(name ="user_id") User user; // other fields and getters/setters } And second: public class User { Long id; @OneToMany(mappedBy = "user") private Collection<Photo> photos; // other fields and getters/setters } I am trying to get this DTO: public class UserDTO { Long id; List<String> photosUrls; } But I can't find the right solution. I wrote next criteria - find user with photos by login: getCurrentSession().createCriteria(User.class, "user") .createAlias("user.photos", "photos") .setProjection

I have a question very similar to this question . I am selecting all data from table1 for all matching unique combinations of field3 and field4 from table2. Here is my stripped down SQL: select * from table1 as t1 where (t1.field1, t1.field2) in (select distinct field3, field4 from table2 as t2 where t2.id=12345); I need to translate my SQL to Hibernate Criteria. I have my entity objects mapping correctly to the tables and transform the response into the correct result entity, but I cannot get my where clause translated correctly. What I Have Criteria criteria = getSession().createCriteria

I need to send a query to retrieve values that has a specific group of characters as following: Lets say I am interested in 'XX' so it should search for any field that its value starts with 'XX' or has ' XX' (space XX). For example XXCDEF , PD XXRF and CMKJIEK XX are valid results. I have following query that returns the correct results but I need to sort them in a way that it first return those with XX at the beginning then other results. As following: XXABCD XXPLER XXRFKF AB XXAB CD XXCD ZZ XXOI POLO XX Code Criteria criteria = session.createCriteria(Name.class, "name") .add(Restrictions

How can I express this query in hibernate criteria. SELECT anId, SUM(fieldA) AS A, SUM(fieldB) AS B, SUM(fieldA)+SUM(fieldB) AS 'total' FROM tableA GROUP BY anId ORDER BY 'total' DESC LIMIT 5 following criteria should do the trick Criteria criteria = hibernateSession .createCriteria(YourEntity.class); criteria.setProjection(Projections .projectionList() .add(Projections.property("anId").as("prop1")) .add(Projections.sum("fieldA").as("prop2")) .add(Projections.sum("fieldB").as("prop3")) .add(Projections.sqlProjection( "sum(fieldA) + sum(fieldB) as total", new String[] { "total" }, new Type[] {

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 am doing a LEFT OUTER JOIN, but I am only able to apply Restrictions on the first table. Is there a way ti apply on the second table as well? Here is my code: Criteria criteria = this.crudService .initializeCriteria(Applicant.class).setFetchMode("products", FetchMode.JOIN);. This works (applicant has an applicantName property): criteria.add(Restrictions.eq("applicantName", "Markos") Neither of these works (product has a productName property) criteria.add(Restrictions.eq("productName", "product1") criteria.add(Restrictions.eq("products.productName", "product1") // products: the name of the
