Hi Listers, I have a rather strange requirement to diff the results returned by two different REF CURSORS. The background is something like this - There is an existing procedure say X that returns a ref cursor (R1) in an out variable. This procedure code has been majorly refactored into a new procedure say Y which returns yet another ref cursor (R2). What I am being asked to do is programatically diff the results from these cursors R1 and R2. Is it possible to do that? Here is the basic idea of the code. Of course, I simplified the posted code to clarify what I need to get done. I have tried bulk collecting into PLSQL nested tables from each of these procedure returned ref cursors, but further am not able to do a MINUS between the result sets. I will really appreciate any pointers towards helping me solve this. ------ Code Start ----------- create or replace package my_pkg as type my_rec is record (x integer, y integer ); type my_cur is ref cursor return my_rec; procedure orig_proc (i_param_one in integer, o_cur_orig out my_cur); procedure refactored_proc (i_param_one in integer, o_cur_refactored out my_cur); end my_pkg; / create or replace package body my_pkg as procedure orig_proc (i_param_one in integer, o_cur_orig out my_cur) is begin open o_cur_orig for select 1, 2 from dual; end orig_proc; procedure refactored_proc (i_param_one in integer, o_cur_refactored out my_cur) is begin open o_cur_refactored for select 3, 4 from dual; end refactored_proc; end my_pkg; / ------ Code End ------------ -- Regards, Srinivas.
