Counting Records in a Transaction Trigger

Question

I would like to keep a count of the records that come into our database by date, so want to build an insert trigger on the table (if you don't see date=sysdate in the stats table create a new stats record, otherwise just add one to the counter where date=sysdate).
This is fairly straightforward if I use a BEFORE INSERT ON EACH ROW trigger, however for performance reasons I'd prefer to make this a transaction trigger (probably AFTER INSERT).
Our application brings in records and commits hundreds at a time. Is there a way I can get the number of records commited in the current transaction so I can add that to my counter?
Hope this is clear. Currently I have:
CREATE OR REPLACE
TRIGGER table1_insert
     BEFORE insert ON table1
     REFERENCING NEW AS NEW OLD AS OLD
     FOR EACH ROW
declare     
last_date date;
v_rows_processed integer;
BEGIN
     update stats_table set record_count = record_count + 1 where to_char(stats_date,'yyyymmdd') = to_char(sysdate,'yyyymmdd');
     v_rows_processed := SQL%ROWCOUNT;
if v_rows_processed = 0 then
     insert into stats_table (stats_date,record_count) values(sysdate,1);
end if;
END table1_insert;
Is there any way I can do this as a transaction trigger?
Thanks

Can't you get hold of the total rowcount in e.g. a global package variable (or alternatively in a sys_context variable)?
SQL> CREATE TABLE t (a INTEGER)
Table created.
SQL> CREATE OR REPLACE PACKAGE pkg
AS
   g_cnt   INTEGER := 0;
END pkg;
Package created.
SQL> CREATE OR REPLACE TRIGGER t_1_trg
   AFTER INSERT
   ON t
   FOR EACH ROW
BEGIN
   pkg.g_cnt := pkg.g_cnt + 1;
END t_1_trg;
Trigger created.
SQL> CREATE OR REPLACE TRIGGER t_2_trg
   AFTER INSERT
   ON t
BEGIN
   DBMS_OUTPUT.put_line ('Totol Rows inserted: ' || pkg.g_cnt);
  /* Insert in some stats table ..etc .. */
END t_2_trg;
Trigger created.
SQL> EXEC pkg.g_cnt := 0
PL/SQL procedure successfully completed.
SQL> INSERT INTO t
   SELECT ROWNUM
     FROM all_objects
Totol Rows inserted: 43052
