C# .Net事务锁定问题

我在事务锁定方面遇到了一个奇怪的问题，我无法指出问题的根源

我们的客户报告说，他们无法使用系统的一个页面，该页面正在超时。此页执行一个存储过程，其中包含CTE，但根本没有事务。请参阅下面的“我的存储过程”：

当页面仍处于关闭状态时，我尝试在SQL管理上手动运行存储过程，并在1或2秒内执行，没有问题。我正在使用ASP.NETMVC显示此存储过程的结果

我重新启动了服务器，但问题仍然存在。我能够解决这个问题的唯一方法是修改存储过程中的任何一行，执行它，撤消更改并再次执行，然后它神奇地解决了这个问题

有人遇到过这种情况吗？任何帮助都将不胜感激，因为我被要求明天报告刚刚发生的事情，我需要在我们的会议上说一些话：

短暂性脑缺血发作

在某些地方，您使用了select*，仅选择所需的列。 2.当从页面点击查询时，从SQL事件探查器或活动监视器监视查询。 3.如果您面临死锁，请从SQL事件探查器监视死锁，以了解确切原因。

演示如何从C代码调用sp。还向我们展示如何从SQL管理中调用它。运行sp_重新编译是否会消除该问题？我认为是在tmp上，当.Net.BTW调用它时，会导致同一连接内的死锁，在页面关闭期间，我还尝试更改连接字符串上的用户ID，希望它现在可以在不同的会话上执行，并与以前的连接保持任何死锁，但不幸的是，错误仍然存在。如果您认为tmp是一个问题，请不要让它使用SELECT INTO自动创建它。相反，请使用CREATETABLE并插入到该表中。但我怀疑这是原因。
