Exception Handling for Array Binding

Question

Hi
1)
I am using a Stored Procedure.
I am using array binding and if i am sending an array of count 10 to be inserted in a table and only 9 got inserted,i deliberatly inserted one errorneous record in array, the count returned by ExecuteNonQuery() is 10.Why ?
How can i come to know exact number of rows inserted in table, how can i use Output variables, because the array bind count is 10 so if i add an output parameter it gives error ArrayBind count is wrong....
2)
Is it possible to roll back all the inserts if error occurs in any of the insert by Oracle engine.What it does is it inserts all correct records and leaves the errorneous record and doesn't even throw any exception or any message.
Answer - This can be achieved by using OracleTransaction and don't use Exception handling in procedure otherwise there wont be any exception thrown by procedure which is necessary to detect if an error occured during insert.If you use exception handling OracleEngine will insert correct rows and leave errorneous record and return count of inserted + non inserted records which is wrong.
Please help.

You'll need to encapsulate your validation within it's own block as described below:
-- this will die on the first exception
declare
  TYPE T_BADDATA_TEST IS TABLE OF VARCHAR2(1000) INDEX BY binary_integer ;
  tbt T_BADDATA_TEST ;
  aBadTypeFound exception ;
begin
   tbt(0) := 'a';
   tbt(1) := 'b';
   tbt(2) := 'c';
    for idx in tbt.first..tbt.last loop
      if tbt(idx) =  'b' then
          raise aBadTypeFound ;     
      else
          dbms_output.put_line(tbt(idx));     
      end if  ;
    end loop ;
end ;--encapsulate the exception area in a begin/end block to handle the exception but continue on
declare
  TYPE T_BADDATA_TEST IS TABLE OF VARCHAR2(1000) INDEX BY binary_integer ;
  tbt T_BADDATA_TEST ;
  aBadTypeFound exception ;
begin
   tbt(0) := 'a';
   tbt(1) := 'b';
   tbt(2) := 'c';
    for idx in tbt.first..tbt.last loop
      BEGIN
      if tbt(idx) =  'b' then
          raise aBadTypeFound ;     
      else
          dbms_output.put_line(tbt(idx));     
      end if  ;
      EXCEPTION
        WHEN aBadTypeFound THEN
            dbms_output.put_line(tbt(idx) || ' is bad data');       
        WHEN OTHERS THEN
            dbms_output.put_line('exception');       
      END ;
    end loop ;
end ;
output:
a
b is bad data
c
