oracle中取余是用函数mod(numer1,number2)

[sql] 
DECLARE  
  --i NUMBER;  
  BEGIN  
    FOR i IN 1..13 LOOP  
      IF MOD(i,3) != 0 THEN  
        dbms_output.put_line('不是3的倍数的整数:'||+i);  
      END IF;  
    END LOOP;  
   EXCEPTION  
     WHEN OTHERS THEN  
      dbms_output.put_line(Sqlcode||':'||Sqlerrm);  
  END;
