I need to retrieve the identity value after the record has been created for another datasource. I.E. When the record is created in SqlDataSource7 the identity value (4700) would be assigned to Label1.text and used in SqlDataSource8 to insert a new record.
How do I do this? In the CodeBehind retrieve the identity value using SqlDataSource7 Scope_Identity() and putting that value into the SqlDataSource8 ApplicantID column.

I 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 RepliesI'm building a website using ASP.NET and SQL Server, and I use
SELECT PK FROM Table WHERE PK = @@identity
My question is which is better and more reliable to retrieve the last inserted PK for multiuser website, using @@identity or using this:
SELECT MAX(PK) FROM Table WHERE PK = Session ("UserID")
I have an ASP.NET app that logs Audit reports using nHibernate's IPreUpdateListener. In order to set the current user in the Listener events, I was using System.Security.Principal.WindowsIdentity.GetCurrent(). This works fine when debugging on my machine, but when I move it to the staging server, I'm getting the ASP.NET process credentials, not the requesting user.
In the ASP.NET page, I can use Request.LogonUserIdentity (which works fine since I'm using integrated authentication), but how do I reference this user directly without having to pass it directly to my event? I don't want to have to pass this info through the pipeline because it really doesn't belong in the intermediate events/calls.
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 have been searching on here for many hours and read many posts but for some reason I am being slow and cannot figure this out. I am writing a record and need to get the identity field back. I have tried many combinations based on what I have read but the below code is where I am sitting at now. it has appdatasource.ExecuteScalar() underlined and the error says 'ExecuteScalar' is not a member of 'System.Web.UI.WebControls.SQLDataSource'. I would be very grateful if someone could point out what I am missing to get this to work.

I'm in the middle of moving a web application from IIS6 to IIS7. I've enabled "Windows Authentication" and added <deny users="?" /> to the authorization section of my web.config file. When the app was running on IIS6 my users where able to access the web app without logging in because their windows login was automatically recognized. This does not seem to be the case in II7. I can not get a value for "Current.User.Identity.Name" in my ASP.Net code.
View 1 RepliesI am in a serious trouble right now, i wanted to know that how to write a query in LINQ to SQL to retrieve identity column's current value before inserting any value.
I need this cos i m building a windows app n i need to display this value before inserting a record. I have tried DataContext.ExecuteCommand('DBCC CHECKIDENT (Tablename)') but it returns the number of rows modified.
i currently work on an asp.net mvc 2 project and noticed that inside an asp.net mvc view page i can get the user name authenticated via User.Identity.Name, but if i try to use the DsiplayFor method in order to display my model from a view user control, it just does not exist. Could i pass this parameter to my model using additional ViewData parameter that comes with DisplayFor html extension?
View 2 RepliesI just not created a new database with 2 tables in it. In a table, I have set a column as a primary key and trying to change its properties i.e. setting is Identity to YES, but am not able to do so.
View 2 RepliesSo far it seems like I get something figured out then run into another issue... Anyways, I was finally able to grab an ID from a table and enter the value into a Label using this code:
[Code]....
Now i want to make things trickier by grabbing the last value enterd. Now there will possibly be multiple people using the application simultaneously, i think it is still possible to do this. Here is the statement that enters VALUES into the table that generates the CaseID that i want to grab from:

From what i have researched, I may need to do a WHERE some where to grab the @@IDENTITY. I am having trouble figuring out where the @@IDENTITY goes, and possibly the correct syntax as well.
