[hibernate-dev] CharacterTypeMapping within Oracle10gDialect

Hi, I just wonder if there is any reason, why the Oracle10gDialect uses the characterTypeMapping of the Oracle9iDialect, and doesn't implement its own. As far as I know is the usage of long-columns in Oracle10g "deprecated" and should be replaced by clobs. Shouldn't look the mapping something like this? ---- snippet ---- protected void registerCharacterTypeMappings() { registerColumnType( Types.CHAR, "char(1 char)" ); registerColumnType( Types.VARCHAR, 4000, "varchar2($l char)" ); registerColumnType( Types.VARCHAR, "clob" ); } ---- snippet ---- Or are there any reasons why I should prefer the usage of long-columns within hibernate.
