SchemaUpdate does not create column indexes (MySql) --------------------------------------------------- Key: HB-1458 URL: http://opensource.atlassian.com/projects/hibernate/browse/HB-1458 Project: Hibernate2 Type: Improvement

Components: toolset Versions: 2.1.8 Environment: Hibernate version: 2.1.8, MySQL version: 4.0.20, MySQL driver: mysql-connector-java-3.0.10-stable (also verified with 3.0.16 and 3.1.7) Reporter: Keith Wall Priority: Minor Attachments: CSDiff.txt, hibernate3.jar, hibernate3.jar.description.txt From forum thread: http://forum.hibernate.org/viewtopic.php?t=939655 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.
