DataSource Controls :: LINQ To SQL - Foreach - To CSV?
Jun 11, 2010
I'm close to the solution I see where I am going wrong just unsure how to approach it. I want to be able to take a tables worth of data (via DataClasses) and put it in a CSV to download.
A LINQ to SQL query is performed (basically a 'Select All' from tbl_Newsletter), takes those results and the idea is to feed those results, one by one through the foreach which, inside it, is the CSV's definition e.g. List.Add(etc) as you'll see. After which the CSVExporter method is called - which works, as I can Download it, it just wont display any results.
C#: [Code]....
To which I get: Compiler Error Message: CS1729: 'Newsletter' does not contain a constructor that takes '2' arguments
with Newsletter obj = Newsletter.GetAll(); in place of Newsletter obj = new Newsletter();
I get: Compiler Error Message: CS0029: Cannot implicitly convert type 'System.Collections.Generic.List<Newsletter>' to 'Newsletter'

I'm using Entity to SQL to retrieve some data from the database and i'm using it to fill an DataList.The query bellow is correct and working properly. My problem is when i try to convert it to an List.I've tried with foreach(EncomendasProdutos ec in produtos)but with no sucess ("Cannot convert type 'AnonymousType#1' to 'cenatolim.EncomendasProdutos'").
Is it because i'm joining tables? I need to save the values of some fields like IVA and Final from all products of the result, but i don't know how.[Code]....

this is my code
[code]....
basically, the InstellingGegevens table gest filled in by some procedure from another server.
the thing i then need to do is check if there are new records in this table, and fill in the new ones in Instellingens.
this code runs for like 4 minutes on 15k records. how do I optimize it? or is the only way a Stored Procedure?
this code runs in a timer, running every 6h. IF a stored procedure is best, how to I use that in a timer?

My question is that, for each control the Stored Procedure called or not? If it is yes then it is time consuming and I need to use LINQ to DataSet or LINQ to Object rather than to call SP for each control. What is difference between LINQ to DataSet and LINQ to Object?

I am trying to use a linq query to create a report and I am unclear on how to traverse the linq dataquery in my case. Inside my for each loop, i have a do while loop. The way it is written below, the do while loop is infinite because I never skip to the next itm in oneSchedule. Placing a Next inside the do while loop causes a syntax error. So what is the correct method for moving to the next itm within the loop?????

Whenever you want to implement Linq to SQL on a project there is inevitably a battle between the DBA and the developers over it.
From the developer standpoint, Linq to SQL eliminates the need to manually write stored procs, ADO.NET data access classes, business object classes, and datatable -> business object conversion classes. This makes development a breeze and eliminates a lot of the traditional layers that you'd normally have to code.
Alternately, from a DBA perspective there are some issues. One is that a lot of DBA's like to do security at the sproc level, and this level would be gone. Another issue is that if the DBA wanted to mimic some sql functionality that the application is doing, possibly for a scripted action, they wouldn't be able to simply call the sproc that the application is using. Also they wouldn't be able to tell which columns are actively being used and which are not, as it'd be C# code specifying which columns are returned rather than sprocs. Lastly, if something needed to be changed structurally, it'd require a recompile and redeploy of the entire app rather than a simple sql script of 2 being deployed.
There are valid points on both ends, so I'm wondering what experiences you all have with this and what sort of compromises you made. In my situation, I'm the developer and I'm trying to figure out a compromise I can make with the DBA so we both give a little rather than one of us having to completely bend over. The obvious compromise to me is using sprocs from within Linq to SQL, but it adds another layer of development and the sprocs have to coded a certain way to play nice with Linq to SQL.

I thought I'd read that LINQ to SQL performs operations on the user's behalf and acts pretty much in the same way as if you manually queried a database.
