Clob column are not getting updated, even if there is real updated in the Clob data, when we do merge operation --------------------------------------------------------------------------------------------------------------- Key: HHH-5566 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5566 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2 Environment: Spring2.5.6, Hibernate3.3.2, Weblogic10.3.1, Red Hat Linux, Oracle10G Reporter: Srinivasa Rao Yedluri Assignee: Gail Badner Below is the hbm file snippet <hibernate-mapping> <class name="......OrderLineDTO" table="ORDER_LINES" dynamic-update="true"> <id name="lineId" type="long" column="LINE_ID" length="15"> <generator class="sequence"> <param name="sequence">xyz</param> </generator> </id> .................................. .................................. .................. <property name="installationDetailClob" type="clob" column="ORDER_LINE_ATTRIBUTES_MAP" not-null="false" lazy="true" /> <property name="attathmentMetadataClob" type="clob" column="ORDER_ATTACHMENT_METADATA" not-null="false" lazy="true"/> <!-- Associations --> <!-- bi-directional many-to-one association to OrderHeader --> <many-to-one name="orderHeader" class="......" fetch="select"> <column name="HEADER_ID" not-null="true" length="15" /> </many-to-one> <!-- bi-directional many-to-one association to SmartHand --> <set name="smartHands" inverse="true" lazy="false" cascade="all,delete-orphan"> <key> <column name="LINE_ID" /><!-- a foreign key in SMART_HANDS referencing the primary key of this table. --> </key> <one-to-many class="...................SmartHandDTO" /> </set> </class> </hibernate-mapping> DAO Code snippet: public void update(OrderHeaderDTO orderHeaderDTO) throws DataAccessException { getOrdersHibernateTemplate().merge(orderHeaderDTO); } 1. Create a table with clob column and have some other columns. Have one column with timestamp. 2. Insert a record in to it. 3. Now create detached object with new operator and populate all the information programatically including pk. Populate clob column and timestamp with different data than already persisted data. 3. Now do merg operation on this object, we find only timestamp column is part of update query but not clob column. Please let me know if you need any more details.
