Modifiers

No modifiers can be used for guid types. They are mapped to uniqueidentifier in Microsoft SQL Server and char(36) in Oracle database platforms.

Since there is no matching data type in Oracle 9i Release 2 for GUIDs, a char(36) data type is generated for persistent properties declared as Guid when using an Oracle database platfrom.
