跟蹤.NET的事務，在SQL

Question

我這樣定義（VB.NET）交易

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

做的過程，然後用

objTransaction.Commit() 
objTransaction.Dispose() 

或

objTransaction.Rollback() 

關閉

如果有錯誤。

現在，如果事務處於打開狀態，如何在SQL中查找「OpenTransaction」？

我做了

SELECT * FROM sys.dm_tran_active_transactions 

，並讓 - NAME = 「user_transaction」，而不是 「OpenTransaction」。如何在SQL中找到我給它的名稱？我有幾個用戶在網頁上做所有不同的事情，我發現在SQL中有一個長時間運行的開放事務，但無法找到我在代碼中給出的名字。

您可以使用SQL事件探查器來達到此目的。你可以啓動SQL管理工作室裏這樣便設置過濾器，並開始跟蹤

你也可以使用此查詢來監控交易：

並創建一個SP。您可以使用

EXEC sp_who3

它會給你所有的用戶，你也可以在你需要編輯它運行的事務。
