PL/SQL Loop Statement Syntax

To iterative sequence of statements repeatedly for a specified number of times, use the following syntax:

LOOP
   ...
   EXIT;
END LOOP;  

PL/SQL Loop Statement example with EXIT Statement

DECLARE counter NUMBER := 100;
BEGIN
  LOOP
    counter := counter + 1;
    DBMS_OUTPUT.PUT_LINE(counter);
    IF counter = 50 THEN
      EXIT;
    END IF;
  END LOOP;
END;
