                                      86549326,
                                      86563882))) col
  FROM DUAL  ;

Answer 2

使用Implicit游标（see more）这是非常自动的：这样怎么样？

--- say table_name as 3 cols: c1, c2, c3
FOR r IN (SELECT * FROM table_name) 
LOOP
  -- do something with r
  dbms_output.put_line('c1 is:'||r.c1);
  dbms_output.put_line('c2 is:'||r.c2)
  dbms_output.put_line('c3 is:'||r.c3)

END LOOP;
