检查以下PLSQL代码以重置密码：

BEGIN
   UPDATE credentials
      SET password = p_password               -- use as parameter in procedure
    WHERE username = p_user;

   -- or you can include "and id = p_id" in where clause
   IF SQL%ROWCOUNT > 0
   THEN
      COMMIT;
      RETURN 'Password Reset Successful.';
   ELSE
      RETURN 'Password Reset Failed. Invalid User Name';
   END IF;
END;
