Varray, Nested Table and Object types in OWB r2

Question

Requirement:
Flat file with repeating groups of nested content need to move into Object Relational ORACLE table (using varray or nested tables - no preference). The data will be loaded, then mapped/transformed into a richer O-R output to directly produce XML outputs.
Problem:
Generated PL/SQL "seems" to do the correct thing, but deployment errors show failures on mapping of collections (varrays, NTs or OTs) and in sqlplus recompiling the PKB still gives the errors. Is this a PL/SQL generator error, or is there a more meaningful example of using CONSTRUCT OBJECT operator than the embedded odcumentation - it is a simple type (single instance) and not a variable repeating group of nested data.
Anyone had any success with these, or know of any collateral to assist in the process. Thanks.

Answer 1

The process we are following is very simple. We are talking 10 columns from a source flat file table and wish to map this into a Varray/Nested table, with one column of Varchar2(10).
When you create your map in OWB, select the construct object, you have to choose an object type - it does not allow you to select a VARAAY or NESTED table.
I have then created an object defined in the same structure as the VARRAY/NESTED table - I have then made the VARRAY/NESTED table of this TYPE.
Example:
CREATE OR REPLACE TYPE "O_REL_PUB_INDEX" AS OBJECT (
X_REL_PUB_INDEX_1 VARCHAR2(10))
CREATE OR REPLACE TYPE "V_REL_PUB_INDEX" AS VARRAY(15) OF O_REL_PUB_INDEX
In OWB you can then select O_REL_PUB_INDEX when creating the 'Contruct Object'.
The problem I have is that when I map to my target column of type V_REL_PUB_INDEX and DEPLOY my map I get the following errors taken from OWB control centre

Any ideas? anyone succesfully mapped to either a VARRAY or an NESTED TABLE target column?
