Using pl/pgsql you can:
....
DECLARE idordinal type;
BEGIN
INSERT INTO tdir_uris_files RETURNING id_ordinal INTO idordinal;
INSERT INTO tdir_uris_files_details (id_ordinal) VALUES (idordinal);
END;
....
Similar results are possible in other environments. If you do not have access to "RETURNING" for some reason you can
issuea select - assuming you can identify the record in tdir_uris_files that you need.

Subject: [GENERAL] Transactions and ID's generated by triggers
Hi,
I have a situation that I dont know how to deal.
I have 2 tables "tdir_uris_files" and "tdir_uri_files_details". Please see the Image in attach.
The table "tdir_uris_files" have the field "id_ordinal" that is originated by a trigger(before insert) The table
"tdir_uri_files_details"use the field "id_ordinal"
generated by trigger on the insert on the table "tdir_uris_files"
Now my doubt. It is possible to do a transaction to this two tables at the same time?
How can I know the value of the field "id_ordinal" that was generated by the trigger?
Can I be able to do this?
[code]
BEGIN;
INSERT INTO tdir_uris_files (uri, id_language, id_category, id_file_context, id_encode_format, n_file, file) values
(...)INSERT INTO tdir_uri_files_details (uri, id_language, id_category, id_file_context, id_ordinal, id_file_type,
id_file_detail,value) values (...); COMMIT; [/code]
PS: Sorry my bad english.
Best Regards,
