[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1651) hibernate does not find an existing sequence from an Oracle database

hibernate does not find an existing sequence from an Oracle database -------------------------------------------------------------------- Key: HHH-1651 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1651 Project: Hibernate3 Type: Bug

Components: core Versions: 3.2.0 cr1 Environment: Oracle 9i on Linux, Windows 2000, Hibernate-3.2, Hibernate-Annotations-3.1beta9 Reporter: Olaf Bigalk Priority: Trivial

Original Estimate: 2 hours Remaining: 2 hours I have setup a hibernate project with a few classes using id generation by the @Id @Generated annotation. The schema update fails due to the following error: ... 07.04.2006 15:12:07 org.hibernate.tool.hbm2ddl.DatabaseMetadata getTableMetadata INFO: table not found: schema.hibernate_sequence 07.04.2006 15:12:07 org.hibernate.tool.hbm2ddl.DatabaseMetadata getTableMetadata INFO: table not found: hibernate_sequence 07.04.2006 15:12:08 org.hibernate.tool.hbm2ddl.SchemaUpdate execute SCHWERWIEGEND: Unsuccessful: create sequence schema.hibernate_sequence 07.04.2006 15:12:08 org.hibernate.tool.hbm2ddl.SchemaUpdate execute SCHWERWIEGEND: ORA-00955: name is already used by an existing object ... The error ocures because hibernate searches for existing sequences by the full qualified sequence name (i.e. "schema.hibernate_sequence") but it has retrieved the existing sequences from the database metadata with its unqualified names (i.e. "hibernate_sequence") . Hence it doess not find the existing sequence. Then it tries to create the pretended non existing sequence and fails. The relevant code ist found in org.hibernate.tool.hbm2ddl.DatabaseMetadata public boolean isSequence(Object key) { return key instanceof String && sequences.contains( ( (String) key ).toLowerCase() ); } It should be somthing like this: public boolean isSequence(Object key) { if (key instanceof String) { String keyString = (String) key; if (sequences.contains( keyString.toLowerCase() ) { return true; } String [] strings = StringHelper.split(".", keyString); if(strings.length==3) { return sequences.contains( strings[2].toLowerCase(); } else if (strings.length==2) { return sequences.contains( strings[1].toLowerCase(); } }
