Question

我创建了一个包含两个输入的包，如下所示，但是我在测试包时遇到了问题，看它是否有效。我想调用该过程并测试它的输入为1和1000.有人能建议在Oracle Apex中进行测试吗？我不确定我是否以正确的方式在包内生成输出，如果我在程序和包之外测试代码它可以正常工作。在那一刻，我只想在SQL命令中测试它。

                                  lv_end_date       OUT DATE,

这听起来像你想要的

DECLARE
  lv_end_date       date;
  -- Guessing at the length.  You'll be better served using anchored
  -- types everywhere
  lv_work_desc      varchar2(100);  
  lv_police_officer number;
  lv_work_days      number;
  lv_staus          varchar2(10);
BEGIN
 PL_WORK_ALLOCATION_PKG.PL_WORK_ALLOCATION_PP(
    <<first parameter>>,
    <<second parameter>>,
    LV_END_DATE,
    LV_WORK_DESC,
    LV_POLICE_OFFICER,
    LV_WORK_DAYS,
    LV_STATUS );
END;

当然，您可能希望对通过呼叫返回的值执行某些操作。
