Hibernate (XML mapping) insert fail - java
I'm trying to insert a new register but when Hibernate creates the insert it doesn't put the FK value.

On the insert is there isn't the Id_Socio value.
INFO [STDOUT] Hibernate: insert into Turno (Nombre,
Apellido, PlanMedico, FechaHoraLlegada, FechaHoraAtencion, Importe,
Observaciones) values (?, ?, ?, ?, ?, ?, ?)

ERROR [JDBCExceptionReporter] Værdien NULL kan ikke indsættes i
kolonnen 'Id_Socio', tabellen 'grupo1.dbo.Turno'. Kolonnen tillader
ikke null-værdier. INSERT kan ikke udføres.
UPDATE
I've already checked that the Socio's, Practica's, and Prestador's ID exists in the database.
I'm giving to Turnos all these classes as attributes, it gets them correctly but at the time it does the Insert operation, is not inserting the FK values.

Hibernate insert query
During insertion in hibernate query i'm passing some fields as table class objects which i've mapped to corresponding tables, The query works fine but the query is becoming too large because each of these mapped objects are getting updated individually to their corresponding tables.

The unwanted updates come from the "cascade all" settings. You may want to configure it properly according to your needs. For example, have a look here: http://www.mkyong.com/hibernate/hibernate-cascade-example-save-update-delete-and-delete-orphan/
Use dynamic-insert=true and dynamic-update=true at class level After this your query will be short. It will insert and update only the specified not null values.
Insert into join table in many-to-many relationship
Problem #1:
I have three tables; User, UserRole, and UserRoleRelationships (join table). The UserRole table contain all the user roles which I want to associate with the user. When I insert a new user I want to add a new user and add a new association in the join table. Now, when I'm running the query for inserting a new user:
IWUser iwUser = new IWUser();
iwUser.setUsername("username");
iwUser.setFullName("fullName");
iwUser.setEmail("email");
iwUser.setPassword("password");
iwUser.setPrivatephone("55555");
iwUser.setWorkphone("777");
Set<IWUserRole> roleList = new HashSet<IWUserRole>();
IWUserRole iwUserRole = new IWUserRole();
iwUserRole.setRole("ROLE_USER");
roleList.add(iwUserRole);
iwUser.setUserRole(roleList);
iwUserManagementService.saveOrUpdate(iwUser);
hibernate is running the following queries:
Hibernate: insert into dbo.Users (Username, Password, Email, Workphone, Privatephone, FullName) values (?, ?, ?, ?, ?, ?)
Hibernate: insert into dbo.UserRoles (Role) values (?)
Hibernate: insert into UserRoleRelationships (UserId, RoleId) values (?, ?)
My hibernate mapping looks like:
IWUser.hbm.xml:

</hibernate-mapping>
How can I get hibernate to save the new user with an existing user role in the join table?
Problem #2:
When I update the user, hibernate delete the relations in the join table. How can I avoid this?
How can I get hibernate to save the new user with an existing user role in the join table?
Retrieve the user role entity and put that into the list instead of always creating a new one.
I mean this part:
IWUserRole iwUserRole = new IWUserRole();
iwUserRole.setRole("ROLE_USER");
Instead, you'd issue a query like select r from IWUserRole where r.role = 'ROLE_USER'

Hibernate without primary keys generated by db?
I'm building a data warehouse and want to use InfiniDB as the storage engine. However, it doesn't allow primary keys or foreign key constraints (or any constraints for that matter). Hibernate complains "The database returned no natively generated identity value" when I perform an insert. Each table is relational, and contains a unique integer column that was previously used as the primary key - I want to keep that, but just not have the constraint in the db that the column is the primary key. I'm assuming the problem is that Hibernate expects the db to return a generated key. Is it possible to override this behaviour so I can set the primary key field's value myself and keep Hibernate happy? -- edit -- Two of the mappings are as follows: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated Jun 1, 2010 2:49:51 PM by Hibernate Tools 3.2.1.GA --> <hibernate-mapping> <class name="com.example.project.Visitor" table="visitor" catalog="orwell"> <id name="id" type="java.lang.Long"> <column name="id" /> <generator class="identity" /> </id> <property name="firstSeen" type="timestamp"> <column name="first_seen" length="19" /> </property> <property name="lastSeen" type="timestamp"> <column name="last_seen" length="19" /> </property> <property name="sessionId" type="string"> <column name="session_id" length="26" unique="true" /> </property> <property name="userId" type="java.lang.Long"> <column name="user_id" /> </property> <set name="visits" inverse="true"> <key> <column name="visitor_id" /> </key> <one-to-many class="com.example.project.Visit" /> </set> </class> </hibernate-mapping> and: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated Jun 1, 2010 2:49:51 PM by Hibernate Tools 3.2.1.GA --> <hibernate-mapping> <class name="com.example.project.Visit" table="visit" catalog="orwell"> <id name="id" type="java.lang.Long"> <column name="id" /> <generator class="identity" /> </id> <many-to-one name="visitor" class="com.example.project.Visitor" fetch="join" cascade="all"> <column name="visitor_id" /> </many-to-one> <property name="visitId" type="string"> <column name="visit_id" length="20" unique="true" /> </property> <property name="startTime" type="timestamp"> <column name="start_time" length="19" /> </property> <property name="endTime" type="timestamp"> <column name="end_time" length="19" /> </property> <property name="userAgent" type="string"> <column name="user_agent" length="65535" /> </property> <set name="pageViews" inverse="true"> <key> <column name="visit_id" /> </key> <one-to-many class="com.example.project.PageView" /> </set> </class> </hibernate-mapping>
As you noted in a comment, there're many id generators you can use. E.g., you many find 'increment' convenient. Complete overview http://docs.jboss.org/hibernate/core/3.3/reference/en/html/mapping.html#mapping-declaration-id And hibernate won't care about your db restrictions (both primary keys and foreign keys). In fact, hibernate has no way of knowing about certain db restriction until it's violated. And if restriction doesn't exist, it can never be violated :)
You can remove the <generator class="identity" /> element and set the id manually before saving the object.
