If you are running an SQL Server version bigger than Express, the Activity Monitor of SQL Server Management Studio allows you to make a snapshot of the current activity on the system. 如果您运行的SQL Server版本大于Express，则可以使用SQL Server Management Studio的“ 活动监视器”为系统上的当前活动制作快照。 There, you can see which connection is blocking which other connection. 在那里，您可以看到哪个连接正在阻止哪个其他连接。 You can also see which tables (or other objects) are locked by these connections, giving you a hint on what causes the blocking. 您还可以查看哪些表（或其他对象）已被这些连接锁定，从而提示您导致阻塞的原因。

If you know the SPID of the blocking process, you can run DBCC INPUTBUFFER(xxx) , where xxx is the SPID. 如果知道阻止进程的SPID，则可以运行DBCC INPUTBUFFER(xxx) ，其中xxx是SPID。 If you're using Activity Monitor, you can achieve the same thing by double-clicking the row containing that process. 如果您使用的是活动监视器，则可以通过双击包含该进程的行来实现相同的目的。

I know that it is possible, however, not being a sql guru I can't give you a query to run that will tell you what query is blocking. 我知道有可能，但是，如果不是sql专家，我无法给您提供要运行的查询，该查询将告诉您哪些查询正在阻止。 I will plug an application that I am evaluating which is doing very well for us so far. 我将插入一个我正在评估的应用程序，该应用程序到目前为止对我们来说非常好。

Run a SQL Profiler trace, only including Blocked Process Report (within Errors). 运行SQL事件探查器跟踪，仅包括阻止的进程报告（错误内）。 Keep it running during the day and monitor it for blocking information. 使其保持白天运行并监视其是否有阻塞信息。
