CREATE OR REPLACE PROCEDURE AdelTest IS
tmpVar NUMBER;

BEGIN

  DBMS_OUTPUT.ENABLE(100: in INTEGER);
  DBMS_OUTPUT.PUT_LINE('hi wo');
    tmpVar := 0;
    EXCEPTION
      WHEN NO_DATA_FOUND THEN
      NULL;
    WHEN OTHERS THEN
      --consider logging error then r-raise
    RAISE;
END AdelTest;

如何显示输出(类似于println如何在Java中使用控制台)？
