> SchemaUpdate is failing to create indices specified using the <column> element in the mapping file. There is no error message generated. If I repeat the same test with the SchemaExport utility, the indices are created successfully.
> I include:
> 1) A mapping file that demonstrates the problem. This is a modified version of Simple.hbm.xml included in the Hibernate 2.1.8 distribution.
> 2) SQL sent to the server by SchemaUpdate (starting with a clean DB).
> 3) For comparison, the SQL sent to the server by SchemaExport (starting with a clean DB).
> Mapping file:
> <hibernate-mapping>
> <class name="org.hibernate.test.Simple">
> <id type="long" column="id_">
> <generator class="assigned"/>
> </id>
> <!-- BEGIN MODIFICATION -->
> <property name="name">
> <column name="name"
> index="test_idx" />
> </property>
> <!-- END MODIFICATION -->
> <property name="address"/>
> <property name="count" column="count_" not-null="true" unique="true"/>
> <property name="date" column="date_"/>
> <property name="pay"/>
> <many-to-one name="other" access="field"/>
> </class>
> </hibernate-mapping>
> Result:
> The table is created successfully, the primary key is created successfully, but no index on the column 'name' is created.

> i'm using an hbm.xml as describe below and the 'hibernate.hbm2ddl.auto' is egal to update.
> <class table="featurestat" name=".....">
> <id name="id" type="long" column="idFeatureStat">
> <generator class="increment"/>
> </id>
> <properties name="fsUniqueValue" unique="true">
> ....
> </properties>
> <property name="frequency" .../>
> <property name="idFatherFeature" index="FeatStatDocExtSectFeat" not-null="true" type="long" column="..."/>
> ....
> </class>
> Indexes for pk or unique key are well created, but the index explicity named 'FeatStatDocExtSectFeat' is never created. If i put the property 'hibernate.hbm2ddl.auto' in the cfg.xml as 'create' the index is created. But in my case i have to set my property 'hibernate.hbm2ddl.auto' to update.
