Returning newly created IDs from View with Instead Of

Question

Hi All,
I have the following table:
CREATE TABLE TBLSIM_SUPPLIER_H
    "SS_ID" NUMBER(10,0) NOT NULL ENABLE,
    "SS_GUID" NVARCHAR2(36) NOT NULL ENABLE,
    "SS_NAME" NVARCHAR2(50) NOT NULL ENABLE,
    "SS_H_IS_ACTIVE" NUMBER(1,0) DEFAULT 1 NOT NULL ENABLE,
    "SS_H_RE_ID"     NUMBER(10,0) NOT NULL ENABLE,
    "SS_H_DATE" DATE DEFAULT SYSDATE NOT NULL ENABLE,
    "SS_H_MASTER_ID" NUMBER(10,0),
    CONSTRAINT "TBLSIM_SUPPLIER_PK" PRIMARY KEY ("SS_ID") ENABLE,
    CONSTRAINT "TBLSIM_SUPPLIER_FK_M_ID" FOREIGN KEY ("SS_H_MASTER_ID") REFERENCES "TBLSIM_SUPPLIER_H" ("SS_ID") ENABLE
  )on which is enabled this trigger
CREATE OR REPLACE TRIGGER TBLSIM_SUPPLIER_H_TRG BEFORE
  INSERT ON TBLSIM_SUPPLIER_H FOR EACH ROW BEGIN <<COLUMN_SEQUENCES>> BEGIN IF :NEW.SS_ID IS NULL THEN
  SELECT TBLSIM_SUPPLIER_H_SEQ.NEXTVAL INTO :NEW.SS_ID FROM DUAL;
END IF;
IF :NEW.SS_GUID IS NULL THEN
  :NEW.SS_GUID  := UTILITYPKG.formatted_guid;
END IF;
END COLUMN_SEQUENCES;
END;UTILITYPKG.formatted_guid returns a standard 36chr GUID
I then created a view
CREATE OR REPLACE FORCE VIEW TBLSIM_SUPPLIER
AS
  SELECT SS_ID,
    SS_GUID,
    SS_NAME,
    SS_H_IS_ACTIVE,
    SS_H_RE_ID,
    SS_H_DATE
  FROM TBLSIM_SUPPLIER_H
  WHERE (ss_h_is_active = 1);on which I enabled the trigger
CREATE OR REPLACE TRIGGER TBLSIM_SUPPLIER_INS INSTEAD OF
  INSERT ON TBLSIM_SUPPLIER FOR EACH ROW
    BEGIN
  INSERT INTO TBLSIM_SUPPLIER_H (ss_name, ss_h_is_active, ss_h_re_id, ss_h_date)
    VALUES (:NEW.ss_name, 1, :NEW.ss_h_re_id, SYSDATE);
END TBLSIM_SUPPLIER_INS;I then have a stored Procedure
PROCEDURE SimSupplier_Create(
      cur_tblresource_id_in IN tblresource.re_id%TYPE
    , ss_name_in IN tblsim_supplier.ss_name%TYPE
    , ss_id_out OUT tblsim_supplier.ss_id%TYPE
    , ss_guid_out OUT tblsim_supplier.ss_guid%TYPE
  ) AS
  BEGIN
    INSERT INTO tblsim_supplier (
      , ss_name
      , ss_h_re_id
    VALUES ( 
      , ss_name_in
      , cur_tblresource_id_in
   RETURNING ss_id, ss_guid INTO ss_id_out, ss_guid_out;
  END SimSupplier_Create; What happens is that the RETURNING clause is not available.
Any way of getting the ID & GUID of the just inserted record out of the prcedure?
Thanks
Andrea

Why do you need this instead of trigger? Can't you simply insert into the view? Maybe enable WITH CHECK OPTION to prevent wrong values beeing entered via the view. Or simply insert into the table and not the view. As long as it is done in the procedure, you are safe that there is no priviledge confict.
