identity strategy AUTO uses SequenceStyleGenerator on mssql ----------------------------------------------------------- Key: HHH-6881 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6881 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 4.0.0.CR2 Environment: Hibernate 4.0.0.CR2, JBoss 7.0.2, MSSQL2008, JTDS-1.2.5 Reporter: andreas bleicher Priority: Blocker we are using identity generation with default strategy (GenerationType.AUTO) to support different DBMS (mssql, oracle, mysql) our Id annotations: {Code} @Id @GeneratedValue public long getId() { return id; } {Code} since upgrading to jboss7/hibernate4 we get the following error on mssql when persisting a new entity: 14:33:10,373 ERROR [org.hibernate.id.enhanced.TableStructure] (http--127.0.0.1-8080-3) could not read a hi value: java.sql.SQLException: invalid object name 'hibernate_sequence'. the reason is that instead of the IdentityGenerator the SequenceStyleGenerator is used although we are using the correct MSSQLServerDialect and it returns supportsIdentityColumns() = true. The SequenceStyleGenerator tries to find the 'hibernate_sequence' table which does not exist workaround for mssql by changing code to: {Code} @Id @GeneratedValue(strategy=GenerationType.IDENTITY) public long getId() { return id; } {Code} -- This message is automatically generated by JIRA.
