Question

我正在学习mysql，并已转移到程序。我创建了一个程序，我正在尝试运行它。但是当我运行程序时，我面临很多错误，错误指向没有错误的行，我可以看到，有人可以帮助我吗？

这是我创建的程序

  create or replace PROCEDURE AD_AGENCY_INFO(
  v_ad_id IN ad_agency.AGENCY_ID%TYPE,
  v_cert IN ad_agency.NO_OF_AD_RUNS%TYPE,
  v_price IN ad_agency.CREDIT_WORTHY%TYPE,
  v_agency_id IN ad_agency.AGENCY_ID%TYPE
  ) AS
BEGIN

 UPDATE AD SET AD_ID = v_ad_id, CERTIFICTAION = v_cert, PRICE = v_price where agency_id = v_agency_id;
  INSERT INTO AD_SLOT (AD_ID) VALUES (v_ad_id);

 EXCEPTION
WHEN NO_DATA_FOUND THEN
rollback;

END AD_AGENCY_INFO;

这就是我调用程序的方法

   DECLARE
V_AGENCY_ID NUMBER:=&Enter_Agency_ID;
V_NO_OF_RUNS NUMBER:=&Enter_No_of_Runs;
V_CREDIT_WORTHY CHAR(3):=&Enter_Credit_Worthy;
V_AVAILABLE_SLOTS NUMBER:=&Enter_Available_Slots;
V_STATUS CHAR(1):=&Enter_Status;
  BEGIN
   V_AGENCY_ID := NULL;
V_NO_OF_RUNS := NULL;
V_CREDIT_WORTHY := NULL;
V_AVAILABLE_SLOTS := NULL;
V_STATUS := NULL;

AD_AGENCY_INFO(
  V_AGENCY_ID => V_AGENCY_ID,
  V_NO_OF_RUNS => V_NO_OF_RUNS,
  V_CREDIT_WORTHY => V_CREDIT_WORTHY,
  V_AVAILABLE_SLOTS => V_AVAILABLE_SLOTS,
  V_STATUS => V_STATUS
);
  END;

这是我在运行程序后得到的错误日志

在您用于调用过程的脚本中，您正在使用替换变量。在解释脚本之前，它们将被其值替换。这意味着像V_CREDIT_WORTHY CHAR(3):=&Enter_Credit_Worthy;这样的值为“no”的行将被翻译为V_CREDIT_WORTHY CHAR(3):=no;您会注意到“no”在那里没有引用。为了使用替换变量将字符串传递给PL / SQL脚本，您需要将绑定变量括在引号中：V_CREDIT_WORTHY CHAR(3):='&Enter_Credit_Worthy';。

另一种方法是使用绑定变量。它们被解释为脚本的一部分，因此可以被视为普通变量。要做到这一点，您只需要用冒号替换＆符号。我上面提到的这一行将成为V_CREDIT_WORTHY CHAR(3):=:Enter_Credit_Worthy;。
