Insert on an optional joined table with non insertable properties ----------------------------------------------------------------- Key: HHH-653 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-653 Project: Hibernate Core Issue Type: Bug Components: core Environment: JDK 1.4.2_08, Oracle JDBC driver 9.2.0.4.0 Reporter: Emmanuel Bourg Attachments: join-insert.patch, joined-table-persist.patch Hibernate generates an INSERT on an optional joined table even if the properties of this table are flagged as not insertable. This leads to a database error if the joined table is read only. For example with the following mapping: <class name="Cat" table="CAT"> <id name="id" column="CAT_ID" type="int"> <generator class="sequence"> <param name="sequence">CAT_SEQ</param> </generator> </id> <join table="CAT_INFO" optional="true"> <key column="CAT_ID" /> <property name="tamed" column="TAMED" type="boolean" insert="false" update="false"/> </join> </class> Hibernate will generate two queries, the first one to insert in the CAT table, and the second on to insert in the CAT_INFO table, even if the "tamed" properties is not persisted.
