Question

I work with Oracle 11g.
I have one table:

create table test (one number(2), two number(2));

There are 2 rows:

insert into test (one, two) values (1, 1);
insert into test (one, two) values (2, null);
commit;

Now I create an exceptions table:

create table exceptions(row_id rowid,
                       owner varchar2(30),
                       table_name varchar2(30),
                       constraint varchar2(30));

Now I want to create the primary key for test:

alter table test add constraint test_pk primary key (one, two) exceptions into exceptions;

Of course I get the following error: ORA-01449

But the row that caused the exception is not in the exception table?

Can anybody help me. Thanks in advance

Answer 1

In order to do this, you must first create the constraint disabled:

ALTER TABLE test ADD CONSTRAINT test_pk PRIMARY KEY (one, two) DISABLE;

Then, enable the constraint with exceptions:

ALTER TABLE TEST ENABLE CONSTRAINT test_pk EXCEPTIONS INTO exceptions;

Then you can select the results:

SQL> SELECT * FROM EXCEPTIONS;

ROW_ID             OWNER TABLE_NAME CONSTRAINT
