Question

我定义了这样的事务（VB.NET）

Dim objTransaction As New Transaction(IsolationLevel.ReadCommitted, "OpenTransaction")

执行这些流程，然后使用

关闭它

 objTransaction.Commit()
 objTransaction.Dispose()

或

objTransaction.Rollback()

如果有错误。

现在如果交易是开放的，我怎样才能找到＆＃34; OpenTransaction＆＃34;在SQL中？

我做了

SELECT * FROM sys.dm_tran_active_transactions

并且它给出了 - name =＆＃34; user_transaction＆＃34;，而不是＆＃34; OpenTransaction＆＃34;。如何在SQL中找到我给它的名字？

（我有几个用户在网页上做了不同的事情，我发现在SQL中有一个长时间运行的开放事务，但是无法找到我在代码中给出的名称。）

您可以使用SQL事件探查器来实现此目的。您可以在SQL管理工作室中启动它，然后设置您的过滤器并启动Trace

您也可以使用此查询来监控交易：

并创建一个SP。你可以使用

EXEC sp_who3

它将为您提供用户拥有的所有正在运行的交易，您也可以根据需要对其进行编辑。
