I have a cutomer object that contains a collection of phone objects. The mapping file looks like this ( Note both tables use the version tag).

customer.hbm.xml

<version name="updateCount" type="integer" column="UPDATE_CNT"/>

<bag name="phoneNumbers" inverse="true" cascade="all">
<key column="CUST_ID"/>
<one-to-many class="PhoneNumber">
</bag>

phonenumber.hbm.xml

<version name="updateCount" type="integer" column="UPDATE_CNT"/>

<many-to-one name="customer" column="CUST_ID" not-null="false"/>




Every time I try to insert a customer object with x phone numbers, in addtion to the inserts, I see 1 customer "update" and x phone number "update". This understandably sets the version to 1 in all the inserted rows.

My questions is, why does hibernate do an update after the insert. I want the version field to be 0 not 1.

These are the sql statements generated when i save a customer object with 2 phone number objects in the collection.

Hibernate: select CUST_SEQUENCE.nextval from dual
Hibernate: select PHONE_SEQUENCE.nextval from dual
Hibernate: select PHONE_SEQUENCE.nextval from dual

Hibernate: insert into SC01_CUST (CIF_ID, FRB_CD, NAICS_CD, SIC_CD, PREFERRED_NAME, BIRTH_DT, CITIZENSHIP_STAT, DRIVER_LIC_NBR, DRIVER_LIC_STATE, FIRST_NAME, LAST_NAME, MIDDLE_NAME, GENERATION, HONORIFIC, MARITAL_STAT, SALES_TAX_STAT, TIN, SS_COUNTRY_CD, UPDATE_CNT, CUST_NBR, PREFERRED_CONT, ORG_TYPE, PREFERRED_LANG, CLASS_TYPE, CUST_ID) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 'IND', ?)
Hibernate: insert into SE04_PHONE_NBR (UPDATE_CNT, CUST_ID, EFF_DT, EXP_DT, COUNTRY_CD, AREA_CD, PHONE_NBR, EXT, TYPE, SERVICE_IND, PHONE_NBR_ID) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
Hibernate: update SC01_CUST set CIF_ID=?, FRB_CD=?, NAICS_CD=?, SIC_CD=?, PREFERRED_NAME=?, BIRTH_DT=?, CITIZENSHIP_STAT=?, DRIVER_LIC_NBR=?, DRIVER_LIC_STATE=?, FIRST_NAME=?, LAST_NAME=?, MIDDLE_NAME=?, GENERATION=?, HONORIFIC=?, MARITAL_STAT=?, SALES_TAX_STAT=?, TIN=?, SS_COUNTRY_CD=?, UPDATE_CNT=?, CUST_NBR=?, PREFERRED_CONT=?, ORG_TYPE=?, PREFERRED_LANG=? where CUST_ID=? and UPDATE_CNT=?
Hibernate: update SE04_PHONE_NBR set UPDATE_CNT=?, CUST_ID=?, EFF_DT=?, EXP_DT=?, COUNTRY_CD=?, AREA_CD=?, PHONE_NBR=?, EXT=?, TYPE=?, SERVICE_IND=? where PHONE_NBR_ID=? and UPDATE_CNT=?
Hibernate: update SE04_PHONE_NBR set UPDATE_CNT=?, CUST_ID=?, EFF_DT=?, EXP_DT=?, COUNTRY_CD=?, AREA_CD=?, PHONE_NBR=?, EXT=?, TYPE=?, SERVICE_IND=? where PHONE_NBR_ID=? and UPDATE_CNT=?

Thanks in Advance.

Every update to the relation will update the parent version. The best advice is to let Hibernate do it's job on versioning
