ADO.NET :: Use Linq To SQL To Get The Primary Key Of A Record Just Inserted?
Sep 7, 2010
I'm inserting data into a database with Linq to SQL and would like to access the primary key of that record WITHOUT doing a query for the values I've already captured.
Here is my insert startment:
[Code]....
There is a value in the table that is an auto increment integer.
Rather than doing a query for the pagetitle, description and content I'd like to just access the primary key that I would have just generated by performing the insert.
Is this possible or would I have to perform the query as I've just mentioned to retrieve it?

i 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):

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?

I know this is a common request, I've googled loads but found lots of complicated code for such a simple task.

I followed this BRILLIANT article and found out how to make a data layer, i just need the insert method in this code to return the ID of the record inserted.
For example, when the user captures the details, the save button is clicked, i will want to display in a label "Your Reference Number is "
try and have look at the article so you will understand how the code is, so it will not be hard to edit my code.

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 trying to insert a record into a MySQL Table. I thought that the Insert methods returned the number of records that were successfully inserted. But that is not what I found. My code:
Code:
dim n as integer
n = taProject.InsertProject(pname, descr, idManager, startdate, tenddate, client, disable)
I get n = 0 even though the record is installed. How can I determine if the insert was successful or not?

how can i retrieve the all foreign keys against a single primary key. i mean to say that if a table contain a primary key then it becomes as foreign keys in which tables.
i want to take that nam of that tables and on the base of that tables then i am to delete from all the entries. e.g: if a primary key's column entry deleted then all foreing key entries should also be deleted.
there are 988 tables in a single database. it can't be possible to go for each table to setup foreign key to ON DELETE CASCADE.
.can it have any way to delete against foreign key priority wise? mean to say that parent table contain primary key, child table contain foreign key , now there is another child table which dependent previous child table. then how can i delete all record against it?
i want to do it from programatically. i am using sql server 2005
i have completed this till to that , it retrieves all foreign keys but how to delete now on the base of priority.

I'm building a user control to display detail information on a parent record. The user control will be displayed via an Ajax Modal Popup. The user control works and is displayed when expected. The problem that I'm having is that I'm not able to pass in the primary key for the parent. The control is displayed via the _ItemCommand event of a Repeater. In the markup for the user control, I explicity set the ContactId to 0 to avoid an error when the control loads (its still underdevelopment, eventually that I'll check if the value is valid).
I was assuming that I could change the property in the _ItemCommand event, but obviously its not working.In the Page_Load event this code successfully sets the ContactId property of the control. The _ItemCommand event appears to set the value. However when I set a test label on the user control to the Me.ContactId, its showing '0' as if it was never passed in.

I am currently binding my Detailsview and Gridview together by a "ID" field selectedvalue "1". Which works great except for the fact that I don't want the user to have to go down to the gridview and select the page and then the record to view it in the detailsview.
I have 1 sqldatasource for detailsview and another sqldatasoure for the gridview. Both have the exact same select statement.
I want the gridview and detailsview to automatically display the last record inserted not the first record in the table.

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.

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
