transactionscope

问题 I received the following error when I tried to run a C# WinForms application on a Windows Server 2003 Standard Edition SP1 machine that was connecting to a SQL server 2000, converting the data in the WinForms app and inserting the converted into a SQL server 2005 application. I am connecting to each database using SSPI. The code was contained within a TransactionScope block: System.TimeSpan TransactionTimeOut = new TimeSpan(0, 40, 0); using(TransactionScope Scope = new TransactionScope

问题 I have a TransactionScope() block. It always gets stuck in an insert statement. It appears in the Activity Monitor as a Blocking Task, so it blocks the SQL server, and after the timeout, I get this error: The operation is not valid for the state of the transaction. What’s going wrong? const TransactionScopeOption opt = new TransactionScopeOption(); TimeSpan span = new TimeSpan(0, 0, 1, 30); try { using (TransactionScope scope01 = new TransactionScope(opt, span)) { using (var sqlcon = new

问题 I have a web application that uses the Entity Framework - we make use of the TransactionScope class to provide ambient transactions. Is there any way to tell EF to use a standard T-SQL transaction in preference to DTC transaction? Quite often we make a number of queries to different tables inside one EntityContext and one TransactionScope instance, however this seems to always promote the transaction to DTC I have put a short example together, see below. The query to the individual table

问题 I wrote a class to assist in adding & removing Destinations to a Publication Target using the Core Service. Destinations are normally exposed as a string (with XML content) via the Core Service, so I wrote my own wrappers around that, etc. I now have a situation where I need to update 2 publication targets and thought it would be cool to use a transaction scope to ensure that both targets are updated at the same time. I am however struggling with implementing this. Code working (using

问题 The following code snippet works fine with SQL Server 2008 (SP1) but with Oracle 11g the call to session.BeginTransaction() throws an exception with the message ‘Connection is already part of a local or a distributed transaction’ (stack trace shown below). Using the '"NHibernate.Driver.OracleDataClientDriver". Has anyone else run into this? using (var scope = new TransactionScope()) { using (var session = sessionFactory.OpenSession()) using (var transaction = session.BeginTransaction()) { //

问题 i need to do something like this on a transaction context using(var context = new Ctx()) { using (TransactionScope tran = new TransactionScope()) { decimal debit = 10M; int id = 1; var data = context.Cashier .Where(w => w.ID == id) .Select(s => new{ s.Money }) .Single(); Cashier cashier = new Cashier(){ ID = id }; context.Cashier.Attach(cashier); cashier.Money = data.Money - debit; context.Entry(cashier).Property(p => p.Money ).IsModified = true; context.SaveChanges(SaveOptions.None); tran

问题 Very simple question: is it possible to use System.Transactions.TransactionScope together with SqlBulkCopy ? The documentation Transaction and Bulk Copy Operations doesn't mention anything (at least as of .NET 4.0) and my testing indicates it does not automatically enlist with TransactionScope . 回答1: SqlBulkCopy never enlists into a transaction. SqlCommand also does not do that. Common misconception. The enlistment is performed at the time SqlConnection.Open is called. After that, anything

问题 Does Sql Azure support using TransactionScope() when performing inserts? Below is a code snippet of what I am trying to do. using (var tx = new TransactionScope(TransactionScopeOption.RequiresNew, new TransactionOptions() { IsolationLevel = IsolationLevel.ReadCommitted })) { using (var db = MyDataContext.GetDataContext()) { try { MyObject myObject = new MyObject() { SomeString = "Monday" }; db.MyObjects.InsertOnSubmit(myObject); db.SubmitChanges(); tx.Complete(); } catch (Exception e) { } } }

问题 Can anyone update me on this topic? I want to support both SQL Server and Oracle in my application. Is it possible to have the following code (in BL) working for both SQL Server and Oracle without escalating/spanning to distributed transactions (DTC) ? // dbcontext is created before, same dbcontext will be used by both repositories using (var ts = new TransactionScope()) { // create order - make use of dbcontext, possibly to call SaveChanges here orderRepository.CreateOrder(order); // update
