[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2354) Schema validation too rigid for MySql enums

Schema validation too rigid for MySql enums ------------------------------------------- Key: HHH-2354 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2354 Project: Hibernate3 Type: Bug

Components: metamodel Environment: jboss-seam-1.1.0.GA, MySQL 5 Reporter: Zeljko Trogrlic

Enum column type in MySQL is handled as CHAR in their JDBC driver and should be mapped to String Java type. However, Hibernate expects varchar(n) and fails to do the validation. This is how DatabaseMetaData.getColumns describes it: DATA_TYPE=1 TYPE_NAME=enum Note that although TYPE_NAME is enum, DATA_TYPE represents CHAR. Hibernate reports following exception: 13:49:31,397 INFO [TableMetadata] table found: configuration.userdb_domain_acl 13:49:31,397 INFO [TableMetadata] columns: [id, enabled, tablename, domain] 13:49:31,397 WARN [ServiceController] Problem starting service persistence.units:ear=msmgui.ear,unitName=msmgui javax.persistence.PersistenceException: org.hibernate.HibernateException: Wrong column type: enabled, expected: varchar( 2) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:698) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:127) at org.jboss.ejb3.entity.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:264) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) Validation should be fixed/relaxed to avoid this problem.
