[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3828) Criteria: Restriction whith class does not work

Criteria: Restriction whith class does not work ----------------------------------------------- Key: HHH-3828 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3828 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.3.1 Environment: Oracle, HSQLDB Reporter: Kai Prünte Assignee: Strong Liu Fix For: 3.5.0-Beta-4 Attachments: HHH3828.ZIP The following line does not work: Restrictions.eq("class", Bike.class) because SingleTableEntityPersister.getDiscriminatorSQLValue() returns the discriminator value quoted with single quotes. However JDBC needs the string without quotes. Workaround: Restrictions.eq("class", Bike.class.getName()) This works fine for the default discriminator values Patch in CriteriaQueryTranslator.getTypedValue(Criteria subcriteria, String propertyName, Object value): if(stringValue != null && stringValue.length() > 2 && stringValue.startsWith("'") && stringValue.endsWith("'") ) { // remove the single quotes stringValue = stringValue.substring(1, stringValue.length() - 1); }
