✍: FYIcenter.com
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:
CREATE OR REPLACE PROCEDURE FYI_CENTER AS
CURSOR emp_cur IS SELECT * FROM employees
WHERE manager_id = 101;
BEGIN
FOR row IN emp_cur LOOP
DBMS_OUTPUT.PUT_LINE('Name = ' ||
row.first_name || ' ' || row.last_name);
END LOOP;
END;
/
Name = Nancy Greenberg
Name = Jennifer Whalen
Name = Susan Mavris
Name = Hermann Baer
Name = Shelley Higgins
