早上好，
请多多包涵;我继承了一个经典的ASP环境，这当然是出乎意料的，而不是我的特权 . 在此先感谢您的考虑 .
设置是这样的;存储过程，接受参数以根据传递的参数返回用户活动数据 . 存储过程在我从SQL Management Studio运行时期望的每个参数情况中返回我的预期结果 . SQL Server环境是SQL Server 2008 Service Pack 3 10.00.5500.00
位于管理面板中的经典ASP页面包含一个包含位置列表的下拉菜单 . 如果您选择一个位置，页面将重新加载到该位置“实例”;包含相应location_id的全局SITE_ID变量用正确的loaction_id填充 . 我通过输出SITE_ID来测试这一点以确保 .
问题是在页面加载时它有时会将结果返回到页面，但有时却没有 . 当它完成时，数据完全符合预期 . 当没有返回记录集时，我注意到如果我在几分钟后刷新页面，页面通常会正确显示记录集 . 如果我切换到另一个位置实例，它总是最初没有返回任何内容，但是几分钟后它通常会在刷新时返回 .
我不能把手指放在上面，并怀疑我不熟悉的代码（但通常可以理解发生了什么）可能很快就会关闭连接？
有趣的是;我将下面的代码片段添加到页面上的输出中，当记录集返回此代码段时不会触发 . 当记录集未返回时，页面上将显示所有五条Response.Write消息 .
任何想法或建议都是最受欢迎的 . 我很感激你的时间 .
