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]....

DataSource Controls :: Using A Variable As A Parameter In A SQL Statement

Mar 25, 2010

I've done some SSIS package work in the past, but am by no means an expert.

I want to use an SSIS package to do the following:

1. Get the file name of the newest file in a windows folder (using a filename template like his: filename_ *.txt where the * part is always a date in the format of yyyy-mm-dd.

2. Use that file name in later portions of the SSIS package by reading the file and transferring data from it to a SQL table using a Data Flow task.

and use the result (which should be the name of the newest file) to open that file and pull data out of it and into a 2nd SQL table. I admit, I'm not sure how to use the dynamic result of this SELECT query as the file name in a flat file connection manager.

DataSource Controls :: Sql Statement To Get One Record Each From Two Tables?

Feb 2, 2010

I don't know if I'm posting this in the right place - I have a feeling it can't be too difficult but I can't seem to figure it out. I've come across this problem many times and I've never solved it. I would imagine the scenario is commonplace - I have a table of Products with a PK of ProductID, and a table of related images with a FK of ProductID. Each product can have many images, but for my initial display I want to display one product record with one image record. I have a Sequence field in the Images table and I could pick the lowest one. Right and left Joins return too many records - if I have three images for Product 1 then Product 1 is listed three times.

I've gotten around this before using a flag in the Products table, or listing an image in both tables but I'm sure there must be a SQL statement that can get the information that I need.

DataSource Controls :: Update Statement Using Linq To SQL?

Jun 22, 2010

I have a method to execute two "Update" sql statements.

The first one works fine and the second one I can't get to work for nothing.

Here is the entire method:


The error I am getting is "Incorrect syntax near '05'."

It is occuring on the next to the last line which is:


I update the variable "sql" first so I can debug. At the time it crashes the value of sql is:

"Update Blogs set Status = 'Archived', ArchiveDate = 06/22/2010 05:14:46 PM Where (BlogID != 1) and (Status = 'Published') and (AuthorID = 9e37e028-c205-4903-920e-e8643b30a724)"

It appears to be the ArchiveDate that is causing the problem here. The "05" is the hour of the time portion. Both ArcgiveDate and PublishDate are defined exactly the same in the database. If you look at the first dc.ExecuteCommand it does exactly the same
thing with PublishDate (DateTime column) in the same table and it works just fine.

Then I modifed the code and remove the ArchiveDate from the sql statement then I get the error:

"Incorrect syntax near 'e028'."

which as you can see is part of the AuthorIDs value in the where clause. So I am assuming both the date and the Guid / Author ID is causing problems. I have tried enclosing the values in quotes but I just cant make this work even though it seems to be working fine in other places.

I even remove the code for the author ID and left in the code for the ArchiveDate and it still does not work so I have proved that both are causing a problem.
