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 issue a select - assuming you can identify the record in tdir_uris_files that you need.

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.
