跟踪.NET的事务，在SQL

Question

我这样定义（VB.NET）交易

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

做的过程，然后用

objTransaction.Commit() 
objTransaction.Dispose() 

或

objTransaction.Rollback() 

关闭

如果有错误。

现在，如果事务处于打开状态，如何在SQL中查找“OpenTransaction”？

我做了

SELECT * FROM sys.dm_tran_active_transactions 

，并让 - NAME = “user_transaction”，而不是 “OpenTransaction”。如何在SQL中找到我给它的名称？我有几个用户在网页上做所有不同的事情，我发现在SQL中有一个长时间运行的开放事务，但无法找到我在代码中给出的名字。

您可以使用SQL事件探查器来达到此目的。你可以启动SQL管理工作室里这样便设置过滤器，并开始跟踪

UPDATE

你也可以使用此查询来监控交易：

并创建一个SP。您可以使用

EXEC sp_who3

它会给你所有的用户，你也可以在你需要编辑它运行的事务。
