Overriding insert error in PL/SQL

Question

Hi all,
I have a piece of PL/SQL code that will insert data into a table in a loop.
Because of some data inconsistency in my original data table, this PL/SQL code does not run at all.
How do I override the errors?
By overriding what I mean is that my procedure should not stop at the first point of inconsistancy.
I dont want to insert inconsistant rows, but all consistant rows must be inserted.
Again I want to show the details of the no of rows not inserted while running the procedure. How do I do that.
for eg: 30 Rows Inserted, 20 rows dropped!
Thanks in advance.

The following piece of code will insert all the proper data and reject unsupported data till the end -
DECLARE
  TYPE EMP_REC IS TABLE OF EMP%ROWTYPE INDEX BY BINARY_INTEGER;
  EMP_TAB EMP_REC;
  CURSOR C1
  IS
    SELECT EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO,CODE
    FROM E_EMP;
  CTR  VARCHAR2(30);
  CTR2 VARCHAR2(300);
BEGIN
  OPEN C1;
  LOOP
    FETCH C1 BULK COLLECT INTO EMP_TAB;
    FORALL I IN 1..EMP_TAB.COUNT SAVE EXCEPTIONS
      INSERT INTO EMP VALUES EMP_TAB(I);
     EXIT WHEN C1%NOTFOUND;
  END LOOP;
  CLOSE C1;
EXCEPTION
  WHEN OTHERS THEN
    FOR i IN 1 .. SQL%BULK_EXCEPTIONS.COUNT LOOP
         dbms_output.put_line(SQL%BULK_EXCEPTIONS(i)
                              .ERROR_INDEX || ' : ' ||
                              SQLERRM(-1 * SQL%BULK_EXCEPTIONS(i).ERROR_CODE));
    CTR := SQL%BULK_EXCEPTIONS(i).ERROR_INDEX;
    CTR2 := -1 * SQL%BULK_EXCEPTIONS(i).ERROR_CODE;
    INSERT INTO EMP_AUD VALUES(CTR,CTR2);
    END LOOP;
     DBMS_OUTPUT.PUT_LINE('NUMBER OF INSERT STATEMENT FAILED : '||SQL%BULK_EXCEPTIONS.COUNT);
END;I hope you can take an idea from this code.
