create or replace procedure t as
total number:=0;
cursor c1 is select sal from emp;
begin
for i in c1 loop
total:=total+i.sal;
dbms_output.put_line('total salary is $'||total); end loop;
end;
/  

exec outln_pkg.drop_by_cat('DEFAULT');
create outline on select sal from emp;

  All,

  I am unable to make stored outlines work for sql statements with bind variable in stored procedures. Please see following sample code and tell me what am I doing wrong.

  Thanks in Advance

  create table emp (num number,sal number);   insert into emp values(1,1);    

  create or replace procedure t(num_i number) as   total number;
  cursor c1(p1 number) is select sal from emp where num=p1;   begin
  for i in c1(num_i) loop
  total:=total+i.sal;
  dbms_output.put_line('total salary is $'||total);   end loop;
  end;
  /    

  alter session set sql_trace=true;
  exec t(1);
  alter session set sql_trace=false;    

  create outline on select sal from emp where num=:b1;   select used from dba_outlines;

  alter session set QUERY_REWRITE_ENABLED=true;   alter session set STAR_TRANSFORMATION_ENABLED=true;   alter session set use_stored_outlines=true;   exec t(2);
  select used from dba_outlines;

  variable b1 number;
  exec :b1:=1;
  select sal from emp where num=:b1;
  select used from dba_outlines;

  Thanks
  Shaleen
