Answer 1

Why do you want to do this?
SQL> create table temp_table (x number);
Table created.
SQL> ed
Wrote file afiedt.buf
  1  create or replace function temp_table_cnt return number is
  2    pragma autonomous_transaction;
  3    v_cnt number;
  4  begin
  5    select count(*) into v_cnt from temp_table;
  6    return v_cnt;
  7* end;
SQL> /
Function created.
SQL> ed
Wrote file afiedt.buf
  1  create or replace trigger trg_a_temp_table
  2  after insert on temp_table
  3  for each row
  4  declare
  5    v_cnt number;
  6  begin
  7    v_cnt := temp_table_cnt();
  8    if mod(v_cnt,1000) = 0 then
  9      dbms_output.put_line('Email Sent for '||v_cnt||' records.');
10    end if;
11* end;
SQL> /
Trigger created.
SQL> set serverout on
SQL> ed
Wrote file afiedt.buf
  1  begin
  2    for i in 1..3456
  3    loop
  4      insert into temp_table values (i);
  5      commit;
  6    end loop;
  7* end;
SQL> /
Email Sent for 0 records.
Email Sent for 1000 records.
Email Sent for 2000 records.
Email Sent for 3000 records.
PL/SQL procedure successfully completed.
SQL>... however I wouldn't consider this good design, as it requires each of the rows to be committed so that the autonomous transaction procedure can count the number of rows on the table. Of course, if the rows are being inserted through, let's say, user input and are committed on a 1 by 1 basis anyway, then it's perfectly acceptable, but I wouldn't use it for bulk insertions.
