Passing c# DataTable as a parameter to stored procedure in MS SQL Server 2008 [closed]

Answer 1

First you need to create a type:

CREATE TYPE dbo.whatever AS TABLE
(
  Supp_Id          int, 
  Del_Methode_Id   int,
  Ord_Amount       int,
  Promo_Id         int,
  Discount_Amount  Money
);

Now your stored procedure can declare this as a read only input parameter:

CREATE PROCEDURE dbo.do_whatever
  @datatable dbo.whatever READONLY
AS
BEGIN
  SET NOCOUNT ON;

  INSERT dbo.destination_table(column_list)
    SELECT column_list FROM @datatable;
END
GO

Why you want to use a cursor here, or think you need one, I'm not sure. You can add an ORDER BY clause to the INSERT...SELECT if you think that will be useful (and there is something meaningful to order by), but otherwise if you really really want a cursor here you should be able to declare one against @datatable just as you would for any other table.
