Problem in creating Entity for view which has "INSTEAD OF " trigger

Question

Hi ,
I have an entity based on a Non updatable Database view (DB_VIEW).this database view has an INSTEAD OF trigger which validates
and save data into a table.
And I have a BC4J view based on this entity.
Problem :
When I try to insert a record using bc4j view object,I get following error
ORA-22816: unsupported feature with RETURNING clause
Query sent by view Object is :
BEGIN INSERT INTO DB_VIEW(COLUMN1,COLUMN2,COLUMN3) VALUES (:1,:2,:3) RETURNING ROWID INTO
:4; END;
I am not able to insert any record in that view.
I tried removing rowID from my BC4J entity and View but problem is that in Databae view there is no
column which can be set as a primary key other then ROWID.

Answer 1

I had the same problem.
Oracle 9.2 sadly does not support the RETURNING clause for database views with INSTEAD OF triggers.
Here is Steves Solution:
1. Create a custom entity def impl class for your entity on the Java panel
2. override the isUseReturningClause() and return false
That should work in 9.0.3.4, 9.0.4 build 1419, and 9.0.5.1 production.
from How to disable generation of RETURNING clause?
