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 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); } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
