Returning Inserted Row Identity ID
Oct 17, 2004
I am inserting a record by calling a stored procedure in my asp.net code. I need to return the identity field from the insert to use elsewhere in my code. I have found many things regarding this but nothing has worked.
Here is my code that works for the insert....
conClasf.Open()
strSQLInsert = "Exec spInsNewCAR '" _
& calDateInitiatedPopup.SelectedDate _
& "', '" & calResponseDatePopup.SelectedDate _
& "', '" & elbPartName.Selectedtext _
& "', '" & elbPartName.Item(elbPartName.SelectedValue).Text2 _
& "', '" & calSupplyDatePopup.SelectedDate _
& "', '" & elbMRBApproval3.Selectedtext _
& "'"
cmdAd = New OleDbCommand(strSQLInsert, conClasf)
cmdAd.ExecuteNonQuery( )
conClasf.Close
Here is the last part of my stored procedure. BTW, I have added Scope_Identity to the end of my sp and when I open my sp up, it is not there...not sure what that is about. I guess my main problem is what command do I use in ASP.net to execute the sp AND hold my returned value...
Thanks,
JOE

i recently found a little error in a stored procedure that was included in a project handed over to me....
the sp was rather simple. it just inserted a record into a table and returned the identity and the timestamp as follows
IF @@ERROR>0
BEGIN
SELECT @int_InterventionID = 0
RETURN @@ERROR
END
ELSE
BEGIN
SELECT @int_InterventionIDReturned = MAX(InterventionID) FROM tblIntervention
SELECT @ts_TimestampReturned = [Timestamp] FROM tblIntervention WHERE InterventionID = @int_InterventionIDReturned
SELECT @int_InterventionID = @int_InterventionIDReturned, @ts_Timestamp = @ts_TimestampReturned
RETURN 0
END
i figured that it should be using @@Identity for the interventionIdentity rather than max(InterventionID)
so i changed to...
IF @@ERROR>0
BEGIN
SELECT @int_InterventionID = 0
RETURN @@ERROR
END
ELSE
BEGIN
SELECT @int_InterventionIDReturned = @@IDENTITY
SELECT @ts_TimestampReturned = [Timestamp] FROM tblIntervention WHERE InterventionID = @int_InterventionIDReturned
SELECT @int_InterventionID = @int_InterventionIDReturned, @ts_Timestamp = @ts_TimestampReturned
RETURN 0
END
it returns the @int_InterventionIDReturned but the timestamp now comes back as null??? why??
how can i ensure that i always get the timestamp of the record it has just inserted
any help greatly appreciated,
Cheers,
Craig

There are loads of postings on the net about this problem but none I have found explain the cause.
Whenever returning a value from a TableAdapter.Insert method followed by a SELECT SCOPE_IDENTITY() , the value returned is always 1. I have run the same select in SQL management studion and the correct value is returned but with a 1 showing in the column selector (just to the left of the first column. The column selector column is not data column. This must be the reason that issuing a SELECT after an INSERT does not work when using a TableAdapter isert method.
Has anyone come across the solution for this issue?
Thanks

This isn't so much purely a SQL Server question as a question on ASP.NET VB technique. In particular, I have a situation where I am either inserting a NEW row for a "profile table" (name, email, etc.) or Updating an existing one. In both cases, I need to create a new row in a related table which has the identity/serial column of the parent table as the primary key for the data to be inserted into this subsidiary table (for which there may be many rows inserted, all tying back to the parent).
At the time I do the update, of course, I have the identity/serial of the "parent" so it's easy to update/insert. However, if the profile is NEW, I need to capture the identity/serial which was inserted so as to use it for the child table insert. (I remember a call to an obscure function which was -- essentially -- "give me the identity/serial of that which was just INSERTed" but I am unable to locate equivalent functionality. (I have searched various online help files for "Insert serial", "Insert identity" and the like with no results.
Hints? Mahalos in advance ... :) KevInKauai

I am using VS.net (2003) SQLcommand TEXT. with input params.
SQL server 2000
Can anyone tell me how to get the Identity value (field value, Idenity col) when you do an insert? I want to get the Identity value, then redirect the user to another page and use this identity value so they can update more (other) fields that are on that page.
My code so far that works... but Where do I put @@IDENTITY ?
How do I call or assign the @@IDENTITY value to a value in my aspx.vb code page?
Question: how do I get the Identity value from the ID column.
Question: How do I assign that value to some variable in code, say, assign it to (Session("App_ID")) = IdentityValueOrSomething?Help...
---------------------
INSERT INTO App
(AppName, Acronym, Description,bla bla bla bla........)
VALUES (@AppName, @Acronym, @Description, bla bla bla bla........)
-----------------------------
Private Sub btnAddApp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddApp.Click
With cmdAddApp
'.Parameters("@app_id").Value = Session("App_ID")
.Parameters("@AppName").Value = txtAppName.Text
.Parameters( bla bla bla.............
.Parameters( bla bla bla.............
.Parameters( bla bla bla.............
End With
Try
cnAppKBdata.Open()
cmdAddApp.ExecuteNonQuery()
cnAppKBdata.Close()
''''''''''''''Session("App_ID") = whatever the @@IDENTITY is....'''''''''''''''''''''''''''??
Response.Redirect("AppUpdate.asp")
Catch ex As Exception
End Try
End Sub
Anyone have the lines of code that does this?
Any advise or examples :) thanks you.

Ok I've been researching this for a day now and I'm not coming up with much. I want to store the auto-incrementing ID of the last inserted record in a session variable, so that I may put it in a foreign key column in another table, if the user wishes to fill out a form on another page. I think my stored procedure is correct. But don't know what code to add to my aspx page. Any help will be greatly appreciated.

Best way to retrieve the identity key of the record just inserted?This question is for discussion purposes; the business process that spurred the question is currently working.Using SQL Server 2008 R2, a record is inserted from a stored procedure. Let's say the sp has something like this:
Code:
BEGIN
BEGIN TRANSACTION
INSERT INTO tblTools
([Desc],CreateDate,Model,CreatedBy,Notes)
[code]....
In Access, when you add a new record to the recordset, the identity field comes "pre-populated" making it east to get the actual, correct identity value assigned to the record you are inserting. In SQL Server, I know options include:
Code:
IDENT_CURRENT('tblX')
SCOPE_IDENTITY
@@IDENTITY
among other methods.
Each has pros and cons, such as user privileges (IDENT_CURRENT requires the user to have Select privileges on the table, and catches records created by other things, such as users and triggers), and the other two give you the last key inserted and don't allow specifying the object (which is a problem if the insert added records to multiple tables, or you have multiple inserts).

I have a table with the following specifications:
[FutureArticleId] [bigint] IDENTITY(1,1) NOT NULL,
[cFutureArticleTitle] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[cDescription] [ntext] COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[gCategoryId] [bigint] NOT NULL,
[cKeyword] [ntext] COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[bIsDeleted] [bit] NOT NULL CONSTRAINT [DF_tbl_FutureArticle_bIsDeleted] DEFAULT ((0)),
[tOnCreated] [datetime] NOT NULL,
[tOnUpdated] [datetime] NULL,
[gCreatedBy] [bigint] NOT NULL,
[gUpdatedBy] [bigint] NULL,
After some insertions and deletion from the UI, obviously there are gaps in the FutureArticleId column which is an identity column.
However, sometimes while inserting the records the records are being inserted into the gap and not in the next available Identity value.
Is there any table setting which I need to do, to stop this.
Please let me know
Thanks

hey everyone, I have the following SQL:
CREATE PROCEDURE [dbo].[sp_InsertItem]
@item_channel_id INT, @item_title VARCHAR(75), @item_link VARCHAR(75),
@item_description VARCHAR(150), @item_long_description VARCHAR(1000),
@item_date DATETIME, @item_type VARCHAR(20)
AS
IF (@item_type = 'article')
BEGIN
INSERT INTO items (
item_channel_id, item_title, item_link, item_description, item_long_description,
item_date, item_type
) VALUES (
@item_channel_id, @item_title, @item_link, @item_description, @item_long_description,
@item_date, @item_type
)
END
IF (@item_type = 'mediaItem')
BEGIN
DECLARE @new_identity INT
DECLARE @new_link VARCHAR(100)
INSERT INTO items (
item_channel_id, item_title, item_link, item_description, item_long_description,
item_date, item_type
) VALUES (
@item_channel_id, @item_title, @item_link, @item_description, @item_long_description,
@item_date, @item_type
)
SET @new_identity = @@IDENTITY
SET @new_link = @item_link + @new_identity
UPDATE items
SET item_link = @new_link
WHERE item_id = @new_identity
END
GO
Basically, what I am trying to do is this...
IF the item type is article, insert normally... which works fine...
however, if the item time is mediaItem, insert part of the item_link... (everything minus id.. eg: site.com/items.aspx?item_id=)... then once the row has been inserted, update that row, to make the link site.com/items.aspx?item_id=<new id>
however, when the sql runs the mediaItem code, it leaves the item_link field blank.
Why is this doing this?
Thanks all!

Hello!I use a procedure to insert a new row into a table with an identitycolumn. The procedure has an output parameter which gives me theinserted identity value. This worked well for a long time. Now theidentity value is over 700.000 and I get errors whiles retrieving theinserted identitiy value. If I delete rows and reset the identityeverything works well again. So I think it is a data type problem.My Procedure:create procedure InsertProduct@NEWID int outputasbeginset nocount oninsert into PRODUCT(D_CREATED)values(getdate()+'')set nocount offselect @NEWID = @@IDENTITYendMy C# code:SqlCommand comm = new SqlCommand("InsertProduct", sqlCon);comm.CommandType = CommandType.StoredProcedure;comm.Parameters.Add(new SqlParameter("@NEWID",System.Data.SqlDbType.Int)).Direction =System.Data.ParameterDirection.Output;try{SqlDataReader sqlRead = comm.ExecuteReader();object o = comm.Parameters["@NEWID"].Value;//...}catch ( Exception ex ){throw ex;}The object o is alwaya System.DbNull. I also tried to use bigint.Any hints are welcomeCiaoSusanne

Hello,
Using VS 2008 Beta 2, SQL CE 3.5, on desktop, and Typed Datasets: The INSERT command of dataset table adapter does not return the updated identity of inserted row. Why?
also every time I want to modify the insert command to return the updated identity of inserted row, i get the error: "Unable to parse query text."
(Should I post this in Orcas forum?!)

I have a problem described as follows: I have a table with one instead of insert trigger:
create table TMessage (ID int identity(1,1), dscp varchar(50))
GO
Alter trigger tr_tmessage on tmessage
instead of insert
as
--Set NoCount On
insert into tmessage
[code]....
When I execute P1 it returns 0 for Id field of @T1.
How can I get the Identity in this case?
PS: I can not use Ident_Current or @@identity as the table insertion hit is very high and can be done concurrently.Also there are some more insertion into different tables in the trigger code, so can not use @@identity either.

I have a stored procedure that inserts a record. I call the @@Identity variable and assign that to a variable in my SQL statement in my asp.net page.
That all worked fine when i did it just like that. Now I'm using a new stored procedure that inserts records into 3 tables successively, and the value of the @@Identity field is no longer being returned.
As you can see below, since I don't want the identity field value of the 2 latter records, I call for that value immediately after the first insert. I then use the value to populate the other 2 tables. I just can't figure out why the value is not being returned to my asp.net application. Think there's something wrong with the SP or no?
When I pass the value of the TicketID variable to a text field after the insert, it gives me "@TicketID".
Anyone have any ideas?

Hi All: I have what I'm sure is a common scenario...I have a table to track pageviews of a form, and which also tracks when a person viewing the form submits it.
The table has three fields: an INT identity/PK field, a DATETIME (default getdate()) field, and a BIT field with default "false".
When the page is viewed, I insert a record into the dB:
Protected Sub Page_load(ByVal src As Object, ByVal e As EventArgs)
conn = New SqlConnection("Server=myserver;Database=mydb;User ID=user;Password=password;Trusted_Connection=false;")
If Not IsPostBack Then
AddTrack()
End If
End Sub
Sub AddTrack()
Dim myCommand As SqlCommand
Dim insertTrack As String
insertTrack = "Insert PageTracker (submitted) Values (0)"myCommand = New SqlCommand(insertTrack, conn)
myCommand.Connection.Open()
Try
myCommand.ExecuteNonQuery()tempTxt.Text = "<br>Ticked</b><br>" & insertTrack
Catch ex As SqlException
tempTxt.Text = ex.Number.ToString()
End Try
myCommand.Connection.Close()
End Sub
And if I view the page, the record is inserted into the table. But now I need to know the value of the identity field, so when the form is submitted, I can update the field "submitted" from "0" to "1".
The way I would do it in ASP is to add a "SELECT @@identity" to the query, and get the value using RS.nextrecordset. How would I do this in .NET? or is there a better way for me to do this?

Hi,
I have upgraded database from sql6.5 to sql 7.o
I have a table tblnetwork on which identity property
is defined on column networkid.
When I issue the following command new record is getting inserted into
tblnetwork and identity column is getting incremented properly.
But, I am not able to get the @@identity value
It is returned as NULL.
insert tblnetwork(formalname,networktype)
values ("name2",11897)
select @@identity
I need this value to insert into some other table.
Pls suggest me why @@identity is returning NULL
thanks,

This group has been really helpful on a couple of recent qwuestions I have posted - thanks to all!
Now, I have another question. I have a table set up to automatically generate a uniquie number when a record is added(INT NOT NULL IDENTITY).
Now, when this number is generated, I need it returned back to my perl script (thorough DBD::ODBC). Any ideas how to do that?
Thnaks....

Hi All,
I have a createStudent SProc. When this is called it calls a createContact SProc. This in turn calls a Create Address Stored procedure. Now when I create the address, an Identity column automatically creates a new Identity for me. I need to return this value back to the calling stored procedure. I know how to return a value and all, however, how to I get the identity just entered (the corresponding identity) reliably? I know that select MAX <Identity> could suffice in this case, but is flawed as if someone was to add another object near the same time we could get the wrong identity returned...
Thanks heaps
Chris

I am storing product information in a SQL Server database table; the product information has no unique fields so I have created an Identity field called ‘uid’. Is there a way of querying the table to find out what value will be given to the next ‘uid’ field before the next record is written to the table? I need to use this as a FK in other tables.

I am trying to get the identity of an inserted record using this SP:
<code>
ALTER PROCEDURE acereal_Admin.AuctionInsertCommand
(
@AuctionID Int OUTPUT,
@StartDate char(255),
@StartTime char(255),
@Location char(255),
@Title char(255),
@Description char(255),
@Images char(255)
)
AS
INSERT INTO Auctions
(
StartDate,
StartTime,
Location,
Title,
Description,
Images
)
VALUES
(
@StartDate,
@StartTime,
@Location,
@Title,
@Description,
@Images
)
SELECT AuctionID AS ID
FROM Auctions
WHERE (AuctionID = @@IDENTITY)
</code>
Then, I am using this class for a file called dataaccess.cs to return the ID:
<code>
public string SaveImageName(string ImageName, string AuctionID)
{
SqlConnection
sqlConnection = new
SqlConnection(ConfigurationSettings.AppSettings["ConnectionString"]);
this.newSqlCommand = new
System.Data.SqlClient.SqlCommand("[AuctionImageSave]", sqlConnection);
this.newSqlCommand.CommandType =
System.Data.CommandType.StoredProcedure;
SqlParameter
paramImagePath = new System.Data.SqlClient.SqlParameter("@ImagePath",
System.Data.SqlDbType.Char, 255);
paramImagePath.Value = ImageName;
this.newSqlCommand.Parameters.Add(paramImagePath);
SqlParameter
paramAuctionID = new System.Data.SqlClient.SqlParameter("@AuctionID",
System.Data.SqlDbType.Int, 4);
paramAuctionID.Value = AuctionID;
this.newSqlCommand.Parameters.Add(paramAuctionID);
SqlParameter
paramImageID = new System.Data.SqlClient.SqlParameter("@ImageID",
System.Data.SqlDbType.Int, 4);
paramImageID.Direction = ParameterDirection.Output;
this.newSqlCommand.Parameters.Add(paramImageID);
//Return SqlDataReader Struct
this.newSqlCommand.Connection.Open();
this.newSqlCommand.ExecuteNonQuery();
this.newSqlCommand.Connection.Close();
int returnID = (int)paramImageID.Value;
return returnID.ToString();
}
</code>
The above code returns null.
Can anyone tell me what I am doing wrong?
THanks, Justin.

Hello, I have a C# application that adds records to a SQL Server database using a query something like this one:
INSERT INTO table_name
(first_name, last_name, date_added) ('john', 'smith', '1/1/2005 12:00:00pm') ;
SELECT SCOPE_IDENTITY() AS [Scope_Identity]
This works fine unless there's already a John Smith in the database. When that happens, Scope_Identity is null even though the date_added is different. About half the time the record is added even though Scope_Identity is null. I've added code to notify me when this happens, but it's a pain in the neck to re-run my import utility for individual records.
(The table I'm adding to does have a autonumbered key field)
Thanks in advance!

Is there a nice solution to this problem?Any help appriciated

I am opening a simple command against a view which joins 2 tables, so that I can return a column which is defined as a tinyint in one of the tables. The SELECT looks like this:
SELECT TreatmentStatus FROM vwReferralWithAdmissionDischarge WHERE ClientNumber = 138238 AND CaseNumber = 1 AND ProviderNumber = 89
The TreatmentStatus column is a tinyint. When I execute that above SQL SELECT statement in SQL Server Management Studio (I am using SQL Server 2005) I get a value of 2. But when I execute the same SQL SELECT statement as a part of a SqlDataReader and SqlCommand, I get a return data type of integer and a value of 1.
Why?

I hvae a stored procedure that has this at the end of it:
BEGIN
EXEC @ActionID = ActionInsert '', @PackageID, @AnotherID, 0, ''
END
SET NOCOUNT OFF
SELECT Something
FROM Something
Joins…..
Where Something = Something
now, ActionInsert returns a Value, and has a SELECT @ActionID at the end of the stored procedure.
What's happening, if that 2nd line that I pasted gets called, 2 result sets are being returned. How can I modify this SToredProcedure to stop returning the result set from ActionINsert?

While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,
Barkingdog
