Deferred Constraints - error on inserting

Question

Hi there,
i've got a very courios problem with deferred constraints. My table creates are:
CREATE TABLE mitglied
( svnr NUMBER(10) NOT NULL,
  instr VARCHAR(20) NOT NULL,
  CONSTRAINT mitglied_pk PRIMARY KEY (svnr));
CREATE TABLE abteilung
( instr VARCHAR(20) NOT NULL,
  geleitetVon NUMBER(10) NOT NULL,
  stvVon NUMBER(10) NOT NULL,
  CONSTRAINT abteilung_pk PRIMARY KEY (instr),
  CONSTRAINT abteilung_geleitetVon_fk FOREIGN KEY (geleitetVon)
             REFERENCES mitglied(svnr) INITIALLY DEFERRED DEFERRABLE,
  CONSTRAINT abteilung_stvVon_fk FOREIGN KEY (stvVon)
             REFERENCES mitglied(svnr) INITIALLY DEFERRED DEFERRABLE);
ALTER TABLE mitglied
  ADD CONSTRAINT mitglied_fk FOREIGN KEY (instr)
                 REFERENCES abteilung(instr) INITIALLY DEFERRED DEFERRABLE;My Inserts (from sql-file):
INSERT INTO mitglied VALUES ('1833040984', 'Edwin Neugebauer', '1984', '20-JAN-2005', 'Posaune');
<all of the other "mitglied"-inserts>
INSERT INTO abteilung VALUES ('Posaune', '1833040984', '1512101070');
<all of the other "abteilung"-inserts>
COMMIT;The Error msg:
Error starting at line 79 in command:
INSERT INTO mitglied VALUES ('1833040984', 'Edwin Neugebauer', '1984', '20-JAN-2005', 'Posaune')
Error report:
SQL Error: ORA-02091: transaction rolled back
ORA-02291: integrity constraint (U0426435.MITGLIED_FK) violated - parent key not found
(it's the same for all of the other mitglied-inserts), and of course, I get also errors on the abteilung-inserts.
I've already tried to solve this problem by using "SET AUTOCOMMIT OFF" in sqlplus, but that wasn't the point.
What's wrong with my Constraints?

Answer 1

Please post a complete example cut-n-paste from SQL*Plus window that shows the exact output step by step (as like below).
It apparently works for me as shown below.
SQL> CREATE TABLE mitglied
  2  ( svnr NUMBER(10) NOT NULL,
  3    mName VARCHAR(30) NOT NULL,
  4    gJahr INTEGER NOT NULL,
  5    aDat DATE NOT NULL,
  6    instr VARCHAR(20) NOT NULL,
  7    CONSTRAINT mitglied_pk PRIMARY KEY (svnr));
Table created.
SQL> CREATE TABLE abteilung
  2  ( instr VARCHAR(20) NOT NULL,
  3    geleitetVon NUMBER(10) NOT NULL,
  4    stvVon NUMBER(10) NOT NULL,
  5    CONSTRAINT abteilung_pk PRIMARY KEY (instr),
  6    CONSTRAINT abteilung_geleitetVon_fk FOREIGN KEY (geleitetVon)
  7               REFERENCES mitglied(svnr) INITIALLY DEFERRED DEFERRABLE,
  8    CONSTRAINT abteilung_stvVon_fk FOREIGN KEY (stvVon)
  9               REFERENCES mitglied(svnr) INITIALLY DEFERRED DEFERRABLE);
Table created.
SQL> ALTER TABLE mitglied
  2    ADD CONSTRAINT mitglied_fk FOREIGN KEY (instr)
  3                   REFERENCES abteilung(instr) INITIALLY DEFERRED DEFERRABLE;
Table altered.
SQL> INSERT INTO mitglied VALUES ('1833040984', 'Edwin Neugebauer', '1984', to_date('20-JAN-2005', 'dd-mon-yyyy'), 'Posaune');
1 row created.
SQL> INSERT INTO abteilung VALUES ('Posaune', '1833040984', '1512101070');
1 row created.
SQL> commit ;
