Is there a way to get the correct order from the dependent types of a sche

Question

Hi ,
I have a CT facing the following problem:
When trying to built a SQL script to create all the object types within a schema using the DBMS_METADATA packages.
Did insert in a table the names of the types that will be exported following a concrete order, next loop into the table and call the DBMS_METADATA package for each row.
These type are depedent between them, there are some type attributes calling other types and here the issue
First : try to generate the order by created column of dba_objects and when the generated SQL script is launched a lot of type appearing as incomplete state due to the order isn't correct.
Second : try to insert the table ordering by object_id colums of dba_tables view, it appears incomplete types too.
Currently want to insert the table using a recursive query with connect by against the dba_type_attrs starting with the rows when ATTR_TYPE_NAME is not null (the types that are called by other types), but this way has a issue dificult to resolve: the roots of hierarchy are the rows when ATTR_TYPE_NAME is not null and we've dependencies between roots nodes
The question is is there a way to get the correct order from the dependent types of a schema?
Platform: IBM SP AIX
DB version: 9.2.0.7
Any help will be appreciated .
Thanks in advance.

The xxx_dependencies view should give you the dependencies betwee nthe various types. I would look at something along the lines of:
SELECT object_name, referenced_name
FROM (SELECT o.object_name, d.referenced_name
      FROM user_objects o, user_dependencies d
      WHERE o.object_name = d.name(+) and
            o.object_type = d.type(+) and
            d.referenced_type(+) = 'TYPE' and
            o.object_type = 'TYPE')
START WITH referenced_name IS NULL
CONNECT BY PRIOR object_name = referenced_nameThe outer join between user_objects and user_dependencies is required to generate the names of types which are not dependent on other types, or do not have other types dependent on them.
