Java OracleXML putXML & non-unique keys

Question

I am using the XML SQL Utility for java on the client (NT) to insert multi-row XML documents into an ORACLE table. Everything works fine until I hit a row with a non-unique key. It appears insertXML throws an error and the insert stops at that point. Rows after the non-unique key row are not processed.
Is there any way to process all rows of an XML document, telling me how many read, how many inserted, how many not processed??
Also, what about update capabilities? Presently I am not needing to update from XML into ORACLE, all I can do now is insert.
Thanks in advance,
Rick

Answer 1

One way to make this work would be to take advantage of Oracle8i's INSTEAD OF triggers on views.
Basically, you would:
(1) CREATE VIEW someview
AS SELECT * FROM sometable;
(2) CREATE TRIGGER someview_trig
INSTEAD OF INSERT ON someview
DECLARE
BEGIN
-- Check for existence of
-- row using the value of
-- :NEW.pk_column_name
IF (you-found-an-existing-one) THEN
-- Do something here like
-- NULL; to ignore the insert altogether
-- or possible an INSERT into
-- and EXCEPTIONS table...
ELSE
INSERT INTO sometable
VALUES (:NEW.column1, ..., :NEW.columnn);
END IF;
END;
(3) Then point XML SQL Utility at someview
instead of sometable
and you'll be in business, as they say.
