We can use SAVE EXCEPTIONS to handle the bulk exceptions.The purpose of save exceptions is logging the error into error logging table and if you want to commit those inserted data you can commit itotherwise rollback it based on the count of error logging table.Here is an example of SAVE EXCEPTIONS in bulk operation
Create Sample Original Table:
-----------------------------
SQL> CREATE TABLE ann_tab(id1 NUMBER(10) NOT NULL,
2 ename VARCHAR2(20)
3 );
Table created.
-----------------------------------------------------------------
Create Sample error logging table
--------------------------
SQL> CREATE TABLE err_log(record_no NUMBER(10),
2 err_msg VARCHAR2(200),
3 ename VARCHAR2(20)
4 );
Table created.
------------------------------------------------------------------
Without Save Exceptions we cant able to get the error record information. We are getting the error message and everything got rollback.
SQL> DECLARE
2 TYPE ann_nest IS TABLE OF ann_tab%ROWTYPE;
3 v_annnest ann_nest := ann_nest();
4 BEGIN
5 SELECT id1,ename
6 BULK COLLECT INTO v_annnest
7 FROM (SELECT1 id1,'ANN1' ename FROM dual
8 UNION ALL
9 SELECT2 id1,'ANN2' ename FROM dual
10 UNION ALL
11 SELECT NULL id1,'ANN3' ename FROM dual
12 );
13 FORALL i IN1..v_annnest.COUNT
14 INSERT INTO ann_tab(id1,ename)
15 VALUES(v_annnest(i).id1,v_annnest(i).ename);
16 COMMIT;
17 EXCEPTION
18 WHEN OTHERS THEN
19 RAISE;
20 END;
21 /
DECLARE*ERROR at line1:ORA-01400: cannot insert NULL into ("SCOTT"."ANN_TAB"."ID1")ORA-06512: at line19
---------------------------------------------------------------------------------------------
Check the table count everything rolledback
SQL> SELECT COUNT(1) FROM ann_tab; COUNT(1)
----------
0

With Save exception option to save the error record information into err_log table and rolled back the original insert
