C# - Linq To Sql - Executing Multiple Queries On The Same Transaction?

Nov 2, 2010

I am creating entries in a contract table using linq to sql.

One column needs to conditionally be assigned an application number from a range of values.

I'd like to simply increment the max existing value, however it is a multi-user application and I'm concerned about multiple contracts receiving the same app number if they happen too close together.

Is there a way to either force the entire thing to use the same transaction, or to execute both during the same submit?

VS 2005 - Perform An Insert Command In A Master Detail Transaction?

Jul 15, 2010

I find my own way redundant to perform an insert command in a master-detail transaction. Sample, is a Purchase Order, before inserting the details/items will need to find the master key otherwise were not able to make the details connection. Normally we send command to button object which will submit the whole page rather than part of it and these means were not able to capture beforehand the master key to refer in the details.

So, Im thinking of how you do efficiently a master/detail batch update like we normally do in windows apps.

Flush Separate Castle ActiveRecord Transaction And Refresh Object In Another Transaction

Jun 15, 2010

I'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

Mar 15, 2011

I have to find the best way to do this using LINQ. I need to summarize an amount in a iTransaction table by

Account (e.g. 12345) and add that amount to an same Account ( e.g12345) if it exists in a iAccount table . Here is the code which syntax checks ok and tested ok up to the .submitChanges statement (i.e. I stopped and didn't allow the submit.

Following is the LINQ code. (1) Is that a good way to do this. OR should I try the INTERCEPT.

(2) How is the best way to insert a new record/row in the iAccounts table if it DOES NOT exist in the iAccount Table.

ADO.NET :: How To Write SQL Insert Into Query Using LINQ

Oct 13, 2010

How I can write following SQL query using LINQ. There is no default constraint define for the ID column so we have explicitly pass the NEWID().

I want to replicate the products of a company to another company.

Insert Into Products Select NEWID() AS ProductID, ProductName, CompanyID = @DestinationID, ProductCategoryID From Products Where CompanyID = @SourceID

Also once I get these result how can I use InsertAllOnSubmit to insert all the records at once without looping it.

C# - How To Insert A Copy Of A Row (with A New Identity) Using LINQ To SQL

Feb 16, 2011

I have a number of tables that together make up a "Test" that somebody can take. There are multiple types (scripts) of Test a person can take. I'm working on an Edit function that will allow somebody to edit the Test Questions. I want these edited questions to show up on all new Tests of that type, but still show the old questions when viewing past test scores.

To do this each "Test" has a TestId auto-increment identity (along with its name). When a test is edited I want to make a copy of the test with a new TestId and present the questions for editing.

So what is the best way to make the copy and insert it into my table using LINQ to SQL? This:

DataContext db = new DataContext(ConnectionString);
//Copy old test into identical new test but with a different script ID
var oldScript = db.TestScripts.Single(ds => ds.TestScriptId == oldScriptID);
var newScript = oldScript;
db.TestScripts.InsertOnSubmit(newScript);
db.SubmitChanges();

of course tells me that I Cannot add an entity that already exists.

Is the only way to do this to go through every column in the TestScript and copy it manually, then insert it, and the database will give it a new Id?

Use LINQ To Insert Data From Dataset To SQL?

Apr 16, 2010

Let's say I have a dataset in an ASP.NET website (.NET 3.5) with 5 tables, each has roughly 30,000 rows and an average of 12 columns. I want to insert all of the data from the dataset into 5 very-similar-but-not-quite-identical tables in SQL Server 2008. I also want to use LINQ (personal preference - trying to learn something new).

Is it as simple as iterating through the dataset and, for each row, creating a new instance of the associated class, initializing its data with the dataset's row, adding it to the data model, and then doing one giant SubmitChanges at the end?

Are there better ways of doing this with LINQ? Or is this the de-facto standard?
