How To Use an Explicit Cursor without OPEN Statements?

If you want to open a cursor and loop through its data rows in quick way, you can use the FOR ... IN ... LOOP statement in the same way as the implicit cursor. The following tutorial exercise gives you a good example:

  CURSOR emp_cur IS SELECT * FROM employees
    WHERE manager_id = 101;
  FOR row IN emp_cur LOOP
    DBMS_OUTPUT.PUT_LINE('Name = ' || 
      row.first_name || ' ' || row.last_name); 
Name = Nancy Greenberg
Name = Jennifer Whalen
Name = Susan Mavris
Name = Hermann Baer
Name = Shelley Higgins
