[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2429) SQL Character Types Incorrectly mapped to Java objects

SQL Character Types Incorrectly mapped to Java objects ------------------------------------------------------ Key: HHH-2429 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2429 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1 Environment: Hibernate 3.2.1, Oracle10g Reporter: Tyler Van Gorder We have a work flow that allows the user to enter an arbitrary SQL statement to be executed by our application. We pass those queries through session.createSQLQuery(). We ran into a problem with String literals, which are reported by Oracle (ResultSetMetaData) to be CHAR. Reading the JDBC API, CHAR is a fixed length string. Hibernate is incorrectly mapping this to a Character field. We ended up overriding the Oracle dialect with our own as follows: In our constructor, for a dialect that extends Oracle9iDialect: super() registerColumnType(Types.CHAR, "char($l)" ); registerHibernateType( Types.CHAR, Hibernate.STRING.getName() ); The HibernateType is the crucial one and we are overriding the behavior in the base "Dialect" class, so this appears that it would be a problem for all database variants that don't explicitly change this.
