LOOP

A simple loop runs until you explicitly end the loop. The syntax for a simple loop is as follows: 


LOOP

statements

END LOOP;

To end the loop, you use an EXIT or an EXIT WHEN statement. The EXIT statement ends a loop immediately; The EXIT WHEN statement ends a loop when a specified condition occurs. The EXIT WHEN statement can appear anywhere in the loop code.

  5      LOOP
  6         v_counter := v_counter + 1;
  7         DBMS_OUTPUT.PUT_LINE('counter: '||v_counter);
  8         EXIT WHEN v_counter = 5;
  9      END LOOP;
