Answer 1

hi
Examples:
SELECT TXNID INTO :TXNID  FROM SAF
      WHERE
      NEXT_ATTEMPT=(SELECT MIN(NEXT_ATTEMPT)
FROM SAF
WHERE STATUS!='A' AND NEXT_ATTEMPT<=SYSDATE AND ATTEMPTS<10)
AND
      STATUS!='A' AND ATTEMPTS<10 AND
      ROWNUM=1 FOR UPDATE;
   //processing==success  
   UPDATE  SAF SET  ATTEMPTS=ATTEMPTS+1, NEXT_ATTEMPT=NEXT_ATTEMPT+(10/(24*60*60))
          WHERE TXNID=:TXNID;
        commit;
    else
        rollback;
Create trigger trigg_name
  After update of C on A
For each row
Is
declare
Pragma Autonomous_transaction;
  New_val  varchar2(27);
Begin
New_val := :new.C;
Dbms_output.put_line(New_val) ;  
            /* this outputs the new value when
       evoking an update statement on Table A (Column C)  */
If updating then
update A set D=:new.C where C=:old.C;
       /* After compiling the trigger and evoking
          an update statement on Table A (Column C)
          the D column still not being updated */
Commit;
End;
update t1
Set t1.C1 = (Select t2.c1
From t2
Where t1.c3 = t2.c3),
t1.C2 = (Select t2.c2
From t2
Where t1.c3 = t2.c3)
update t2
Set t2.C1 = (Select t1.c1
From t1
Where t1.c3 = t2.c3),
t2.C2 = (Select t1.c2
From t1
Where t1.c3 = t2.c3)Its Correct/Helpful Please mark it.Thanks.
