DataSource Controls :: Use Scope Identity To Get Newly Inserted Table
Feb 14, 2010I have an SQL Server table named "Fields" with an autoincrement identity column "FieldID" as the primary key, an nchar column "Phrase" that textbox entries are to be stored in from a web page, and another column that is defaulted to null. The following is the recommended example on how to use Scope_Identity() to get a newly inserted table row identity value:
//C#
string query = "Insert Into Categories (CategoryName) Values (@CategoryName);" +
"Select Scope_Identity()";
int ID;
string connect = @"Server=.SQLExpress;AttachDbFilename=|DataDirectory|Northwind.mdf;" +
"Database=Northwind;Trusted_Connection=Yes;";
using (SqlConnection conn = new SqlConnection(connect))
{
using (SqlCommand cmd = new SqlCommand(query, conn))
{
cmd.Parameters.AddWithValue("@CategoryName", Category.Text);
conn.Open();
ID = (int)cmd.ExecuteScalar();
}
}
Obviously, this example uses a Categories Table in a Northwind database, which I do not have. So I am confused by how to adapt this example for my application. The following is my data context:
DataClassesDataContext db = new DataClassesDataContext();
Could you explain how I can adapt the example for my "Fields" table in my "EFMDB" database?

View 2 RepliesDataSource Controls :: How To Get The Primary Key Of The Newly Inserted Record
May 10, 2010I am using a FormView to populate data, then inserting it using a LinqDataSource. The primary key is an autoincrementing identity. I'd like to handle the ItemInserted event to update some other tables, but I cannot find how to get the primary key of the newly inserted record. The insert happens fine, but nothing for the PK.
I realize I can change to using a SPROC, or change to creating the new row and doing the insert myself, but I'd prefer to continue with the LinqDataSource's automatic insert.
How can I get the PK?
DataSource Controls :: Updating A Newly Inserted Row In A Tableadapter?
May 7, 2010I need to insert two rows into a tableadapter - and then take the identity column from each row and update them into a column on each row.
My problem is that I cannot update a column on a newly inserted row. Stepping through the code seems to indicate that I have updated the column, but when I check the database - the column indicates null.
I have tried calling Update on the TableAdapter, then performing the update on the column, and then calling Update again, but the update still isn't taking.

DataSource Controls :: Obtain Inserted Table Row Identity With An Auto Increment Key
Feb 18, 2010I am using LINQ to store and retrieve data from tables with a clustered index key. However, I also need to know how to obtain an inserted table row identity with an auto-increment Primary key. The "Go To Definition" feature for my data context of dataClassesDataContext provides the following information:
[System.Data.Linq.Mapping.DatabaseAttribute(Name="EFMDB")]
public partial class DataClassesDataContext : System.Data.Linq.DataContext
I am asking for the C# code that is needed in a button click event handler that will insert a row of data in a table named "Fields". It only consists of an auto-incrementing primary key column (FieldID), a string column (Phrase) and a null defaulted variable column.

DataSource Controls :: Create An Auto Incrementing ID For Table Rows?
Apr 27, 2010I have an ID column (int) in my table which also needs to be a unique key.
last time I worked with a database (BD2), I set this as an autoIncrement feild and it would automaticaly 'deal with it' (ie, maintain the last used value somewhere and automaticaly used that value (after incrementing it) for any new row on the table).
How do I handle this in ASP.NET. Especially, as I try to add a new line based on form content when the user presses on a button (C#).
