Create global temporary table in delete trigger

Question

Hi to all, I am triyng to create a global temporary table in trigger so i can hold all the deleted rows and do some stuff after the statement which uses the table that fires the trigger.
In this way I am trying to avod mutating table error. but the following trigger gives error.
create or replace
TRIGGER TD_EKSINAVLAR
FOR DELETE ON DERSSECIMI_EKSINAVLAR
COMPOUND TRIGGER
BEFORE STATEMENT IS
BEGIN
CREATE GLOBAL TEMPORARY TABLE DELETED_ROWS
AS ( SELECT * FROM DERSSECIMI_EKSINAVLAR WHERE 1 = 2 )
ON COMMIT DELETE ROWS;
END BEFORE STATEMENT;
BEFORE EACH ROW IS
BEGIN
NULL;
END BEFORE EACH ROW;
AFTER EACH ROW IS
BEGIN
NULL;
END AFTER EACH ROW;
AFTER STATEMENT IS
BEGIN
NULL;
END AFTER STATEMENT;
END TD_EKSINAVLAR;
the error is
Error(12,5): PLS-00103: Encountered the symbol "CREATE" when expecting one of the following: ( begin case declare exit for goto if loop mod null pragma raise return select update while with <an identifier> <a double-quoted delimited-identifier> <a bind variable> << continue close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe purge
Please help me about the situation.
Thanks in advance.

Karthick you are absolutly right
Our main process is to migrate sql server 2000 database to oracle 11g and I am stuck with the triggers that reference to table that fires the trigger itself.
Can you help me about how i can overcome mutating table errors using compund triggers? Espacially for the situation that one statement tries to update or delete multiple rows on a table.
You can understand my logic from the above code. I want to hold all the affected rows in a table and in after statement body using a cursor on that table I want to do required changes on the table. How can I do that or how should I do ?
regards.
