Schema validation fails with floating point column in Oracle 10g ---------------------------------------------------------------- Key: HHH-1961 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1961 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.2.0.cr2 Environment: 3.2 CR 2, Oracle 10g express edition release 2, Windows XP service pack 2, JDK 1.5.0_06 Reporter: Daniel Dyer I have a table (created automatically by Hibernate) for mapping a double field. The table creation from Ant works fine but when starting up JBoss with the hibernate.hbm2ddl.auto property set to validate, I get the following exception: Caused by: org.hibernate.HibernateException: Wrong column type: percentage, expected: double precision at org.hibernate.mapping.Table.validateColumns(Table.java:219) at org.hibernate.cfg.Configuration.validateSchema(Configuration.java:965) at org.hibernate.tool.hbm2ddl.SchemaValidator.validate(SchemaValidator.java:116) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:296) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1176) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:414) at org.hibernate.ejb.Ejb3Configuration.createEntityManagerFactory(Ejb3Configuration.java:575) at org.hibernate.ejb.Ejb3Configuration.createContainerEntityManagerFactory(Ejb3Configuration.java:245) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:108) at org.jboss.ejb3.entity.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:260) ... 127 more Doing a "desc" on the table reveals that the column is of type FLOAT with a length of 22. I think this may be related to issue HHH-1566 or HHH-1008.
