Dynamic bulk upload

Question

Hi,
Please find the below example.In this i am taking a table type variable and using dynamic select ,populating the rowtype variable.Then i changed a one column value of that rowtype variable.
Till this point the thing is working fine . now i want to insert the the updated data back to the root table (with out considering row by row, means on bulk).
Can you please suggest how can i do that...
Thanks,
Anit
Example :-
declare
l_select varchar2(50);
--type g_var    is record (col1  an_test.col1%type,col2  an_test.col2%type);
--g_var1  g_var;
g_var1 an_test%rowtype;
begin
l_select := 'select * from an_test ';
execute immediate l_select into g_var1;
dbms_output.put_line(g_var1.col1);
dbms_output.put_line(g_var1.col2);
g_var1.col2 := 'cc';
dbms_output.put_line(g_var1.col2);
---l_select := 'insert into an_test values (:1,:2);*
--execute immediate l_select using g_var1.col1,g_var1.col2;*
commit;
exception
when others then
dbms_output.put_line(sqlerrm);
end;
--select * from an_test
