Re: Optimizer_Mode

Here is a test for anonymous pl/sql blocks only.

You will have to devise your own for stored procedures.


declare

   v_mode varchar2(30);

begin

   execute immediate 'alter session set optimizer_mode='
      || ''''
      || 'first_rows'
      || '''';


   select value into v_mode
   from v$parameter
   where name = 'optimizer_mode';

   dbms_output.put_line(v_mode);

end;
/

I curious why you are asking this.

Sounds like another Oracle Urban Legend to me.

Is optimizer_mode inside pl/sql program will be always 'ALL_ROWS'
irrespective of what has been set in instance or session level?
