Instead of PROC_RUN_ID_SEQ I am getting-> DEBUG main SQL logStatement:92 - select hibernate_sequence.nextval from dual
The causes can be different:
The name of the sequence you have mapped in your pojo is different
You have no permission to use sequence
You have no defined a sequence on your database
Solutions
Fix the sequence name on your pojo
Grant the sequence for your database user
Add the sequence on your database
EDIT AFTER UPDATED QUESTION
Try as follow:
<id name="propName" type="long" unsaved-value="null">
<column name="columnName" not-null="true" unique="true"
index="pkName" />
<generator

I need to configure hibernate session manager for right inserting records with autoincrement ID. I use Java DB (Derby) and there's probably some problem with application of right dialect (hibernate uses last_insert_id() instead of IDENTITY_VAL_LOCAL()), but its definition looks ok. Or not? I do not have much experience with that yet, so thanks for a little hint.

I want to get the result using this query
select * from sys_def_user where id not in (select UserId from SYS_DEF_GROUP_MEMBERS where GroupID =5)
What can be the nhibernate syntax for this? Please its urget...
You can use NHibernate's LINQ provider for this. The examples listed here, http://code.msdn.microsoft.com/101-LINQ-Samples-3fb9811b, are a good starting point for learning LINQ. Most of those examples are written in the from ... select syntax, but I prefer the extension method syntax:
var subquery = session.Query<GroupMember>()
.Where(gm => gm.Group.Id == 5)
.Select(gm => gm.User.Id);
var users = session.Query<User>()
.Where(u => !subquery.Contains(u.Id));
Hopefully this example will get you started on the right track, and you'll be writing your own LINQ queries in no time.
I'm learning spring hibernate zk stack, and doing my first crud following this tutorial
I put applicationContext.xml into webapp/WEB-INF, and .hbm.xml to resources/mappings
But I dont know why my hbm files keep showing can not find my pojos.
in github https://github.com/kossel/firstzk
I have this structure
applicationContext.xml
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- set other Hibernate properties in hibernate.cfg.xml file -->
<property name="configLocation" value="classpath:/com/iknition/firstzk/hibernate/hibernate.cfg.xml" />
</bean>

</class>
</hibernate-mapping>
UPDATE:
I have reference to contact.hbm.xml too, I missed to put it here.
by "why my hbm files keep showing can not find my pojos" I mean, when I try to build the application, I keep getting error of "Caused by: org.hibernate.MappingException: entity class not found: com.iknition.firstzk.beans.Contact" I have changed many times the location of those configuration files, and still getting same error.
Hmmm... never tried using an external hibernate.cfg.xml. But I think specifying that only loads the properties. You might still need to set the mapping in a separate property.
Here's what my config usually looks like:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<bean
class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="propertiesArray">
<list>
<props>...</props>
</list>
</property>
</bean>
</property>
<property name="mappingLocations" value="classpath:com/iknition/firstzk/hibernate/*.hbm.xml"/>
</bean>
I think you have to specify mappingLocations one-by-one like:
<property name="mappingLocations">
<util:list>
<value>hibernate/Company.hbm.xml</value>
<value>hibernate/Contact.hbm.xml</value>
</util:list>
</property>
Hello,
i have simple J2EE application that shows first 100 Employee records from db (Oracle DB) with Hibernate (version 3). All of the tables have about 10000 records. There are Country(id, name), City(id, name, country_id), Address(id, address, city_id), Company(id, name), Office(id, company_id, address_id), Employee(id, name, address_id), Position(id, name) and Employee_Position_Office(employee_id, position_id, office_id) in db. And i have some problems with batch-size. I need to do it in 4 sql-request (generated by Hibernate). Let's show you what i have:
In my class-mappings i set batch-size=100 and Hibernate creates 3 sql-request for Employee, OfficePosition and Address loading, look:
select * from ( select employee0_.ID as ID6_, employee0_.NAME as NAME6_, employee0_.ADDRESS as ADDRESS6_ from EMPLOYEE employee0_ ) where rownum <= ?
select officeposi0_.EMPLOYEE_ID as EMPLOYEE1_6_1_, officeposi0_.POSITION_ID as POSITION2_1_, officeposi0_.OFFICE_ID as OFFICE3_1_, position1_.ID as ID5_0_, position1_.NAME as NAME5_0_ from EMPLOYEE_POSITION_OFFICE officeposi0_ inner join POSITION position1_ on officeposi0_.POSITION_ID=position1_.ID where officeposi0_.EMPLOYEE_ID in (100x ?)
select address0_.ID as ID2_2_, address0_.ADDRESS as ADDRESS2_2_, address0_.CITY_ID as CITY3_2_2_, city1_.ID as ID1_0_, city1_.NAME as NAME1_0_, city1_.COUNTRY_ID as COUNTRY3_1_0_, country2_.ID as ID0_1_, country2_.NAME as NAME0_1_ from ADDRESS address0_ left outer join CITY city1_ on address0_.CITY_ID=city1_.ID left outer join COUNTRY country2_ on city1_.COUNTRY_ID=country2_.ID where address0_.ID in (100x ?)
And if i change batch-size to number more than 100 nothing changes - this is good.
But then (after these requests) Hibernate generates request(s) for Office loading, and i have some problems with it, let's show you:
My 100 first Employees work in 397 offices (randomly generated) and Hibernate should loads they with 1 request when batch-size is more than 397, when i set batch-size to 397 it works fine (in 1 sql-request),
select office0_.ID as ID4_4_, office0_.COMPANY_ID as COMPANY2_4_4_, office0_.ADDRESS_ID as ADDRESS3_4_4_, (SELECT COUNT(*) FROM EMPLOYEE_POSITION_OFFICE
E WHERE
E.OFFICE_ID=office0_.ID)
as formula0_4_, company1_.ID as ID3_0_, company1_.NAME as NAME3_0_, address2_.ID as ID2_1_, address2_.ADDRESS as ADDRESS2_1_, address2_.CITY_ID as CITY3_2_1_, city3_.ID as ID1_2_, city3_.NAME as NAME1_2_, city3_.COUNTRY_ID as COUNTRY3_1_2_, country4_.ID as ID0_3_, country4_.NAME as NAME0_3_ from OFFICE office0_ left outer join COMPANY company1_ on office0_.COMPANY_ID=company1_.ID left outer join ADDRESS address2_ on office0_.ADDRESS_ID=address2_.ID left outer join CITY city3_ on address2_.CITY_ID=city3_.ID left outer join COUNTRY country4_ on city3_.COUNTRY_ID=country4_.ID where office0_.ID in (397x ?)
but when i set any another number (less or more than 397) Hibernate generates several sql-requests with same "body" but others "tails".
For example, there are results when batch-size = 400.
...in (200x ?)
...in (100x ?)
...in (50x ?)
...in (25x ?)
...in (12x ?)
...in (10x ?)
Tell, please, what i do wrong and can it be fixed. Thx.
