SQL & PL/SQL

Hi,

I've got the following question / problem?
When I do a fetch from a cursor in my for loop and the cursor returns no record my variable 'r_item' keeps the value of the previous fetched record. Shouldn't it contain null if no record is found and I do a fetch after I closed and opend the cursor? Is there a way the clear the variable before each fetch?

Below you find an example code

 
CURSOR c_item (itm_id NUMBER) IS
SELECT DISTINCT col1 from table1
WHERE id = itm_id;

r_item  c_item%ROWTYPE;
...

FOR r_get_items IN c_get_items LOOP
  IF r_get_items.ENABLE = 'N' THEN	   
      
      open c_item(r_get_items.ITMID);
      fetch c_item into r_item;
      close c_item;

      IF  r_item.ACCES = 'E' then
           action1
      ELSE   	 	    
           action2
      END IF;

  END IF; 
END LOOP;  

Thanx
