ADO.NET :: Get The Identity (scope_identity) Value of The Newly Inserted Record?

I 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?
I thought this would be easy before I started, but I should've known better.
I just need to get the value of primarykey from the newly inserted record so I can pass it in the query string to the next page the user will be directed to.

I had found what looked like a good soultion yesterday by the moderator "ecbruck" at this post:
[URL], but after spending many hours trying to figure out why I couldn't get it translated and working in my own project, I found that MS Access does not allow use of an Output Paramter. And unfortunately I don't have time to teach myself a new database platfrom and am stuck with MS Access for the moment...teaching myself asp.net has my head spining enough as it is.
I 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?
after a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e. I'm looking for a kind of automatic 'postback' bringing my just entered data back
View 9 Repliesi cannot retrieve the new identity value from an inserted record(via DataAdapter.Update) in my DataRow.
I'm using a strong typed Dataset as DAL. The table i want to update is joinded with other tables in the SelectCommand, hence the designer cannot automatically generate the insert-/update-/delete-commands and also it cannot "Refresh the DataTable" automatically. [URL]
I've tried to set AutoIncrement=true/false on the primary-key's DataColumn but the result is the same: last MAX-ID+1 instead of the actual ID the database generated(SQL-Server 2005 EP; pk datatype:int, Is identity:yes, Identity Increment:1).
This will be the wrong value f.e if another instance of the application inserted a record that the first instance yet not knows and therefore generates an ID that already exists.
To retrieve the new identity from db i've appended following to my insert-command's CommandText:
;SELECT CAST (SCOPE_IDENTITY() AS int) AS newIdRMA
Also i've tried to add an Output-Parameter to it's parameter-collection:
This is part of my code that updates the database and sets the new ID(that doesn't work):

This would seem to be quite a trivial task, however I am having trouble retrieving the identity of the record inserted using the detailsview.insert() in the code behind. It would seem that detailsview.DataKey.Value would contain this value, but it is null after the insert is performed.
View 4 RepliesI have a Stored Proceedure which DID return the Scope_Identity when this was executed in SQLServer 2000.
Now I am porting this over to SQLServer 2008, and this always returns 0, and not the Scope_Identity which it should.
Here is the Stored Proceedure which will pass null for the parameter @pProjId for an insert:

Here is the script which creates the hip_Project Table:

What do I need to change for SQLServer 2008?
Again, this executed fine in SQLServer 2000 and always returned the Scope_Identity as expected. This problem has come up with other stored proceedures as well for which I need the Scope_Identity returned.
I'm trying to insert data into two tables that are related within a store procedure. After the first insert I want to get the id of the inserted row to use as a parameter during the insertion of data in the other table. I'm sure this is a common task, and I have looked into things like scope_identity(), @@identity and ident_current. However I'm not sure exactly how to use the id as a parameter.My attempt now looks like:
DECLARE @RETURN_VALUE
INSERT INTO Table1(test_name) VALUES ('asdf')
@RETURN_VALUE = SCOPE_IDENTITY()
INSERT INTO Table2(test_name) VALUES(@RETURN_VALUE)
I setup my gridview to handle the edit,delete, and insert operations correctly. My grid also supports paging and sorting. My question is how to highlight and go to the newly inserted row in my grid?

However, the createdAlbumID always shows -1 instead of the id for the newly created album.
I 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.
I am having a table named Invoices.From that table I want everything the newly inserted and updated rows from that table.
View 3 RepliesI am using an auto-numbering index column as the primary key for many of my tables. Is there any way for me to know what the new row count is for newly inserted rows?
View 2 RepliesI am developing a asp.net application and i am using SQL Server 2008. I took a IDENTITY column as Record_ID for detail table where i will have trillions of records per year. So just want to ask whats the largest number record id (identity) column can hold and in ASP.NET which data type i should use to handle record id as i am using this id as a reference to update the table data. I don't want to end up being trapped some day.
View 1 RepliesIm trying to get the ID out of the record that i'm inserting using scope_identity. I've add the following line of code to the Insert statements in the sqldatasource - SET @insID = Scope_Identity() I've add the following line to the Insert parameter list
asp:Parameter
Name="insID"
Type="Int32"
Direction="Output"
I now want to insert a number records into the database using the following:
Dim insID As Object = e.Command.Parameters("@insID").Value ' gets out latest ID
Dim ordernumber As String = "CX" & insID.ToString & DateTime.Now.DayOfYear.ToString
sqlOrders.InsertParameters("orderNumber").DefaultValue = ordernumber
sqlOrders.InsertParameters("orderDate").DefaultValue = DateTime.Now
sqlOrders.InsertParameters("customerID").DefaultValue = userID
sqlOrders.InsertParameters("productID").DefaultValue = productID
sqlOrders.InsertParameters("totalPrice").DefaultValue = "0.00"
sqlOrders.InsertParameters("status").DefaultValue = "Paid"
I currently have this code in the SQLDataSource_Inserting sub but the first line only works once the record is inserted. How can i get the ID out as im inserting the parameters?
I have an orders table with a column names orderID. What I want to do is insert a new record and get the value from the new orderID column. The orderID is my Primary key. The Insert SQL I have now is -
INSERT INTO orders

VALUES (@creditAutorizarionNumber,@OrderName,@OrderPersonPhone,@OrderPersonEmail)
How do I write the query to get the newly entered orderID ?
I am using below code to get new inserted ID in auto identity column from database.

It's working fine when I connect my application with MS Sql, but if I connect with Mysql, it always returns 0 (zero).
Is there any other way to get last inserted ID using Entity Framework?
I have a detailsView that I use for Insert. Once a record is Inserted, I need to get the new idenetity value.
Is there some function that grabs the inserted identity value? Or do I need to query it somehow?
By the way, the reason I'm doing this is the user is inserting a record into a 'general' list that is being applied to a 'specific' list - example, an employee can select a vendor from a list, but the vendor isn't listed so the employee adds the vendor in the vedor list and while the new vendor is inserted, the vendor info is also applied to the new order record.
I 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.
I have a DetailsView using a LinqDataSource. I have it connected to DropDown so the user can select a record to edit. This configuration works. However when I add a record after I enter the data and press insert link the DetailsView reverts to another record. How can I make the DetailsView stay on the newly added record?
My add button calls:
protected void btnAddRec_Click(object sender, EventArgs e)
{
DetailsView1.ChangeMode(DetailsViewMode.Insert);
}

Here's a simple code snippet where I create a new Entity object and call SaveChanges() to create a new record in the mapped database table.
[Code]....
What I'm trying to figure out is whether there is a way to derive this new key for my entity, e, from the ObjectContext, m? The reason for this is that the way my actual code is structured, my entity object is already out of scope at the point where I call the SaveChanges() method.
