How to select multi tables with WHERE clause

I want to get id and name of user, who have mhId = "AAA" (mhId is a column in table User_MonHoc. In User_MonHoc, mhid + user_id are primary key).
Table User:
<hibernate-mapping>
<class name="entites.User" table="user" catalog="bthibernate" optimistic-lock="version">
<id name="username" type="string">
<column name="username" length="100" />
<generator class="assigned" />
</id>
<property name="password" type="string">
<column name="password" length="100" not-null="true" />
</property>
<property name="note" type="byte">
<column name="note" not-null="true" />
</property>
<property name="name" type="string">
<column name="name" length="100" not-null="true" />
</property>
<set name="userMonhocs" table="user_monhoc" inverse="true" lazy="true" fetch="select">
<key>
<column name="user_id" length="100" not-null="true" />
</key>
<one-to-many class="entites.UserMonhoc" />
</set>
</class>
Table User_MonHoc
<hibernate-mapping>
<class name="entites.UserMonhoc" table="user_monhoc" catalog="bthibernate" optimistic-lock="version">
<composite-id name="id" class="entites.UserMonhocId">
<key-property name="userId" type="string">
<column name="user_id" length="100" />
</key-property>
<key-property name="mhId" type="string">
<column name="mh_id" length="100" />
</key-property>
</composite-id>
<many-to-one name="monhoc" class="entites.Monhoc" update="false" insert="false" fetch="select">

</many-to-one>
<many-to-one name="user" class="entites.User" update="false" insert="false" fetch="select">

I want to get id and name of user, who have mhId = "AAA" (mhId is a column in table User_MH).
Thank you!

You should join User and User_MH table in a SQL or HQL query. set alias to User_MH in your query o access User_MH table in where clause:
SQL :
SELECT tbl_user.useranme,tbl_user_mh.user_id FROM User AS tbl_user
INNER JOIN User_MH AS tbl_user_mh ON tbl_user.id=tbl_user_mh.user_id
WHERE tbl_user_mh.mhdl = 'AAA

Hibernate - load children

I have the following Hibernate Mappings:
<class name="Database.Content" table="..." schema="" catalog="...">
<id name="id">
<column name="id" sql-type="int" not-null="true"/>
</id>
<property name="week">

</property>
<property name="type">

</property>
<many-to-one name="group" class="Database.Group">

</many-to-one>
<many-to-one name="table" class="Database.Table">
<column name="table" not-null="true"/>
</many-to-one>
<list name="entries" inverse="true" table="...">
<key>

</key>
<list-index column="id"/>
<one-to-many not-found="ignore" class="Database.Entry"/>
</list>
</class>
<class name="Database.Entry" table="..." schema="" catalog="...">

</property>
<many-to-one name="content" class="Database.Content" fetch="join" lazy="false">
<column name="content" not-null="true"/>
</many-to-one>
</class>
Now I am trying to query all contents with the corresponding entries:
List<Content> contents = session.createQuery("from Content c WHERE c.day IN :days ").setParameterList("days", days).list();
The query returns the correct response. However, when I do the following:
contents.get(0).getEntries()
there is a bunch of null values. What is the correct way to eager load all corresponding entries for each content?
I have about 20,000 content records, and most of the records have only one entry.
If I set lazy="false" for the list of entries, I get Java heap space error.
I ended up fetching entries and joining contents:
List<Entry> entries = session.createQuery("select e from Entry e Join e.content c WHERE c.day IN :days ").setParameterList("days", days).list();
I also changed lazy to proxy in:
<many-to-one name="content" class="Database.Content" fetch="join" lazy="proxy">
<column name="content" not-null="true"/>
</many-to-one>

Add lazy=false attribute:
<list name="entries" inverse="true" table="up_timetable_entries" lazy="false">
Hope helped you!

Try calling:
contents.get(0).getEntries().size();
To force hibernate to load the children.

Hibernate org.hibernate.MappingException... an associon ..to unmapped class- Many toMany

I have auto generated the code using netbeans to create a Hibernate configuration; so I have two tables mapped like this (Many-to-Many) :
<hibernate-mapping auto-import="true">
<class name="com.antoiovi.jobprograms.entity.Roles" table="roles" catalog="jobprograms">

I have made some modification as you can see above (auto-import=true, lazy=false), cause i have the error message
rg.hibernate.MappingException: An association from the table users_roles refers to an unmapped class: com.antoiovi.jobprograms.entity.Roles

public Set<Roles> getRoleses() {
return this.roleses;
}
wHEN RUNNING I HAVE THE ERROR org.hibernate.exception.SQLGrammarException, and in fact the entiti is loaded, but the set<> not..,
When testing the error is
org.hibernate.MappingException: An association from the table users_roles refers to an unmapped class: com.antoiovi.jobprograms.entity.Roles, and the HSQL ar not executed.
I tried to look in others post but i couldn't find an answer. Can anybody help me?
In config file the entities are all declared;
I think yhe promlem is in the mapping :
e <set name="roleses" table="users_roles" inverse="false" lazy="true" fetch="select" >
<key >
<column name="user_name" length="15" not-null="true" />
</key>
<many-to-many entity-name="test.Roles" property-ref="rolesName">

</many-to-many>
</set>
<set name="jobprograms" table="jobprogram" inverse="true" lazy="true" fetch="select">
<key>
<column name="users_idusers" not-null="true" />
</key>
<one-to-many class="test.Jobprogram" />
</set>
and
enter <class name="test.Roles" table="roles" catalog="jobprograms">
<id name="rolesName" type="string">
<column name="roles_name" length="20" />
<generator class="assigned" />
</id>

</many-to-many>
</set>
</class>
....

this error
org.hibernate.MappingException: An association from the table users_roles refers to an unmapped class: com.antoiovi.jobprograms.entity.Roles
comes when hibernate configuration dont know about entity(Roles) mapping , either you have missed introducing enitity Roles to the hibernate configuration or you have not used correct name , please check configuraiton file and included com.antoiovi.jobprograms.entity.Roles as resourse

I think to have resolved the problem. Actually the proble are unmapped entities. But this happens because the database is not 'well formed'. Indeed the database ha 3 table users, users_roles, roles; the table roles has only one column as primarykey (varchar),and the table user_roles refers to it from its column user_roles; when forword enginering the ide (in the case netbeans) creates only 2 entities: 'Users', and 'Roles'; So i have re-designed the schema putting some virtual primary key, and creating unique constaint instead. Now i have 3 entities : Users,UserRoles, and Roles.

I want to achieve something like this:
whereClause.append(" and a.jurisdiction_id not in (select distinct (j.jurisdiction_id) from " +
"task_category_jurisdiction j)" );
There is another Hibernate file for "a" which contains jurisdiction. And where clause is a StringBuffer.
I have tried this:
DetachedCriteria dc1 = DetachedCriteria.forClass(TaskCategory.class);
dc1.setProjection(Projections.distinct(Projections.property("jurisdictions")));
criteriaQuery.add(Restrictions.not(Subqueries.in("a.jurisdiction", dc1)));

Hibernate performance issue with updates more than 10K records

I am presently trying to do a bulk upload operation where in i need to parse an excel and update the details into the database. The problem is the data needs to be stored into multiple tables and the relationship is maintained. The problem is not when i have about 50-100 records to updated, but hugely affected when i have around 50000 records to be updated. It takes ages to upload and sometimes the browser gives up waiting for the response to arrive. Please find below the code and the mapping files. Please let me know what i can do to increase the performance and complete the processing quicker.
Note: The cascades are all required.

Please let me know how i can increase my performance.

The problem is that you are trying to do this from a browser, where the default timeout for a page is 30 seconds. You should be doing this from an application so that you can control the amount of time you wait to upload the records.

I am having lookalike problems.
Make sure that you have all keys for join and search fields.
May be you can store your file in temporary location and then handle it by paralell thread.
Another option is to use Stateless Sessions (there is almost no info on the net, see hibernate manual) I am not sure if there is an option to fill ManyToMany collections.
Caching getOrCreate queries by saving copy of table in memory may help you (but you may run into OutOfMemory exception, so pass -Xmx param to your app).
All these may not solve your problem. I've decided to implement these inserts using native sql queries.

There are multiple issues that should be looked at:
Long-running operations should be run asynchronously. If you are using Spring, you can annotate #Async, for instance. Then your transaction is not beholden to network connectivity or browser/HTTP timeouts.
Batch operations in Hibernate can be very slow. Even if you set up JDBC batching, and even if you follow the instructions in the Hibernate documentation, you are still beholden to the fact that you are using an ORM. ORMS are best used for maintaining state for object-oriented operations, not for batch operations, where any individual object's state is less relevant.
Batch operations in Hibernate can be very finicky. For instance, the Hibernate batching documentation fails to note that you need to set additional flags in the configuration to make sure that it batches correctly. See this post for details.
At the end of the day, ORMs will always be slower than base SQL. Consider swtiching over to base SQL, maybe concatenating SQL statements so that you have fewer database trips, or using a stored proc, passing bactches of data to the proc and have it run the inserts.

when you open session use openStatelessSession and call session.update at the end. this way persistentcontext cannot have 10000 object in cache and all the updates happens in db.
