I'm getting "This SqlTransaction has completed; it is no longer usable" exception when try to commit my transaction after sqlreader is close.Here is the code sample

...so when I get to commit the transaction it raises the mentioned exception: "This SqlTransaction has completed; it is no longer usable". I have also noticet that Command.Transaction becomes NULL after reader.Close()My question is: Can I use SqlDataReader and SqlTransaction ? Maybe to use BeginExecuteReader and EndExecuteReader ?
I have a stored procedure which is part of the aspnetdb but i am using my own database and therefore these stored procedures are added on my sql server locally.So i uploaded the databases to my hosting company 1and1 and created the stored procedures and tables as those in aspnetdb but i get the error as in the title. this is a standard stored procedure which lives in the aspnetdb database but not sure why this is happeningthe code is below which is for aspnet membership createuser a standard stored procedure

I have 20 records in the datatable and i try to insert this records in a database, i want towrite begintransactions , and if all the records correct , i need to commit otherwise i need to rollback.how to do this?
View 2 RepliesI've got all of my ASP.NET requests wrapped in a Session and a Transaction that gets commited only at the very end of the request. At some point during execution of the request, I would like to insert an object and make it visible to other potential threads - i.e. split the insertion into a new transaction, commit that transaction, and move on. The reason is that the request in question hits an API that then chain hits another one of my pages (near-synchronously) to let me know that it processed, and thus double submits a transaction record, because the original request had not yet finished, and thus not committed the transaction record.
So I've tried wrapping the insertion code with a new SessionScope, TransactionScope(TransactionMode.New), combination of both, flushing everything manually, etc. However, when I call Refresh on the object I'm still getting the old object state. Here's some code sample for what I'm seeing:
Post outsidePost = Post.Find(id); // status of this post is Status.Old
using (TransactionScope transaction = new TransactionScope(TransactionMode.New))
{
Post p = Post.Find(id);
p.Status = Status.New; // new status set here
p.Update();
SessionScope.Current.Flush();
transaction.Flush();
transaction.VoteCommit();
}
outsidePost.Refresh();
// refresh doesn't get the new status, status is still Status.Old

View 3 RepliesI know these 2 commands
sp_who and sp_who2 → knowing who are updateing
DBCC log (DB_NAME,4) → I can't really understand these information..
just wondering does there exists a log file, so we can check who have updated database from it?
I have a multiple database operation, Have three tables (MSsql) and need to delete one row in each table in one operation, one after another. (Three functions, three rows of code). Everything is working as it should be, recently I was advised to use a transaction scope, which should guarantee the safety of deletion from all 3 tables together.
Here is my new code:

Locally all worked just fine, the transaction scope worked well, but when I have uploaded my application to my hosting server, I got an error of: The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025).I talked with the host support, they tried to do something, then I got this error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
After a 2 days, They have contacted me, they said it is not possible to disable some restriction, that will allow an access to this operation, because I'm using shared hosting, and I need to upgrade my plan to VPS. VPS is a very expensive for me, and I can't afford it, What I'm looking is a some similar way of doing the same operation as transaction scope do, that may work at my hosting, At least I would like to try something else. Is there any additional way for the transaction scope?

I develop an application using LINQ to SQL. Recently I deploy the application on server and starts performance testing using WAPT for 100 users. Unfortunately, 90 requests are failed while placing an order and only 10 are passed. I analyse and found that for every failed request I got an error "System Exception: Transaction (Process Id 68) was Deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction."

I have to write stored proc to get the daily transaction for a specified date. Right now what i do is everytime i log a transaction in table3 I update table 2 with the count. Then i use table 2 to write the stored proc and to get the desired result. I have pasted my stored proc below with the output. My problem is when another subsystem is added in the AppInfo table i need to update my stored proc because i have hardcoded the subsystem name.

I have a strange situation.An ASP.NET button click event causes an object in memory to be updated. The object was loaded from NHibernate via Refresh() during Page_Load, but at no time during the entire page life cycle is Commit() or Flush() called.At some point after the page's OnUnload step, the object and any changes made to it are automatically persisted to the database. I cannot see when or where or why this occurs.
View 2 RepliesI'm using a LinqDataSource with a RadGrid. When I Add a new Grid item and click insert the values are immediately saved to the database.Is there a way where they can be actually not put in the database until I give the command?
View 1 RepliesI have this page in my application that contains a couple of grids and a few text boxes. Now these grids are getting populated from a hidden field in the page. My requirement is like the main page should have an "Update All" button where as these grids have their individual Update and delete options. Now when I delete or update anything from the Grids it should do a soft update or delete function and eventually when I hit "Update All" an actual commit statement should be executed.
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
begin
GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
TextBox PhoneNo = (TextBox)row.FindControl("TextBox2");

All I am trying to do is to make an update to an existing User and then save the changes to the database. I fooled around with different options and can see that I can make the change to the context during Page_Load, but it does not commit the changes to the Database.
View 5 Repliesi am using the transaction-per-request (session-in-view) pattern for an asp.net web application. I have a couple of points in the application where i want to Save an NHibernate managed entity and then do a couple of more inserts and updates using common sql. These inserts/updates depend on the ID that the NH saved entity will take.
The problem is that the generated id does not exist in the transactions' scope. If i force a flush/commit the id is persisted but if the inserts/updates fail i have to rollback but the flushed/committed entity will not. Currently I'm doing a manual insert for these cases but that is something i want to change. So, is there a way to execute the SQL statement (inside the already open transaction) after the Save() but without forcing a flush/commit?
EDIT: I'm adding a semi-pseudocode example, i got 4 wrong answers so i think people don't understand (how NHibernate works)
At the Begin request i issue a
nhsession.BeginTransaction()
then at some point i do
FooClass fc = new FooClass("value");
nhsession.Save(fc);
ITransaction trans = nhsession.Transaction;
SqlCommand sc = new SqlCommand("some insert/update query that depends on fc's id", (SqlConnection)nhsession.Connection);
sc.Parameters.Add("id", fc.Id); //NHibernate generates the id, note i'm using assigned/hi-lo so no round trip to the db takes place
transaction.Enlist(sc);
try {
sc.ExecuteNonQuery();
}
catch (SqlException ex){
transaction.RollBack();
nhsession.Close();
}
and at the end of the Request i issue a CommitTransaction() and nhsession.Close()
Now this will do absolutely nothing: the FooClass (fc) has not been flushed/commited to the database. The Save() operation that NH has done is up to that point in-memory. That means no sql command has been issued by nhibernate and that means that the SqlCommand (sc) that i fire afterwards will fail miserably as the id does not exist.
If i do a flush/commit between Save() and the SqlCommand the FooClass(fc) _cannot_be_rolled_back_ and that is a bad bad thing.Currently, for this to work i make vanila sql insert using an SqlCommand, and i want to change that. (Why? because i don't want to make vanilla inserts they are susceptible to errors due to schema/model changes, and i got the OR/M for that)
How? i want to notify NHibernate somehow to execute the SqlCommand to corresponds to the Save() insert (hell, it can do all the SqlCommands it has gathered) but without it commiting or flushing!.
Currently i'm also searching for the prepared sql statement that nhibernate produces when flushing/commiting a saved object. Maybe i can just take that string and run it in my SqlCommand that is enlisted in the Transaction.
i have no idea about commit,rollback,tranasaction can any one explain with examples brefiely.
View 2 RepliesI've been looking into how best to do this and wisdom would be appreciated. For read only purposes, I've been happily using LINQ and binding it to a grid. For editing purposes, I've used the LinqDataSource control, enabled the Edit/Delete operations in the process, and I have a nice editable grid bound to some or all of the table's fields.Now I have a situation where I want to edit a few fields in table A, but there are various values in linked table B that I want to display in that grid too (no editing of those). So my query looks like the below. The fields in tblDupes (cleared, notes) are what I want to edit, but I'd like to display those tblVoucher ones.
var theDupes = from d in db.tblDupes
where d.dupeGroup == Ref
select new

A similar but different question LINQDataSource - Query Multiple Tables? sent me looking at scott Guthrie's blog entry http://weblogs.asp.net/scottgu/archive/2007/09/07/linq-to-sql-part-9-using-a-custom-linq-expression-with-the-lt-asp-linqdatasource-gt-control.aspx, where he handles various events to have a LinqDataSource with a custom query across tables. This still seems aimed at explicitly designed classes though, even if the class has only a subset of the fields.
So my question is: is there an easy way to allow committing of the changes made to the anonymous collection (a changes.Submit type action), or just an easy way to 'display' fields from another table while not involving them in the updating?EDIT: Thinking more, it doesn't have to be anonymous really. I'd be happy to define a class to contain the elements in that query, since it won't change often. But, those elements would be across two tables, even though only one needs updating. Not sure if that suggests entity framework would be more suitable - I get the feeling it wouldn't - I don't want the whole 'model' always grouping the fields in this way.

View 2 RepliesI have a multi- statement transcation in my stored procedure, that is either inserting or updating records in table1 and table2.
table1 has a check constraint. Will the check constraint be checked only after I call COMMIT in above transaction, OR will it be checked before I call COMMIT when using INSERT or UPDATE statement?
