Something like
create or replace procedure my_proc( p_rc OUT SYS_REFCURSOR )
as
begin
open p_rc
for select 1 col1
from dual;
end;
/
variable rc refcursor;
exec my_proc( :rc );
print rc;
will work in SQL*Plus or SQL Developer. I don’t have any experience with Embarcardero Rapid XE2 so I have no idea whether it supports SQL*Plus commands like this.
