I have a 1.5 GB file into a table. I want to read It from server and create a file stream with it for save.
When I use DataAdapter.Fill(DataSet); code OutOfMemoryException occurs.
What should I do for read a hage file from data base?
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?
I am trying to insert the data via linq to sql concept. i wrote down the code like this. here customers is the table name in which i want to insert the data. How to achieve it? following code is not working. How to insert the data via this concept.

Dim context As New linq_to_sql_classesDataContext
Dim custid As New Customer

I need to insert large amount of data into SqlServer 2008. My project is based on linq-to-sql.
I process csv file with 100.000 rows. Each row is mapped to Order object. Order contains also collection of Category and Code objects. I need to map each row to object in order to validate it.
Then I need to insert all these objects into database.
List<Order> orders = Import("test.csv");
db.Orders.InsertAllOnSubmit(orders);
db.SubmitChanges();
OR
foreach(Order order in orders)
db.Orders.InsertOnSubmit(order);
db.SubmitChanges();
Both ways are slow. Is there any workaround? I may use other approach than l2sql for this task.
I read about SqlBulkCopy class - would it handle inserting child entities as well?

I'm using Dynamic Data and LINQ to SQL for some admin pages on a .NET 3.5 web app. All my admin tables have a CreatedBy, CreatedDate, UpdatedBy, and UpdatedDate.I'm looking for a way to inject the setting of these properties before the objects are inserted and updated.
I've seen an object_inserting hook if you have a linq to sql datasource in the web form, but I'm using dynamic data...is there an easy way to generically set that? And I've also looked at modifying each of the partial classes for my admin objects, but the closest hook I see is to implement the OnValidate method with the Insert action.
