DataSource Controls :: Retrieve The Identity Value After Insert?
Jan 21, 2010
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.
Protected Sub SubmitApp_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitApp.Click
Dim appdatasource As New SqlDataSource
appdatasource.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString1").ToString
appdatasource.InsertCommandType = SqlDataSourceCommandType.Text
appdatasource.InsertCommand = "INSERT INTO APPLICATION (FirstName,MiddleName,LastName,AcceptTerms,IPv4Address,DateInserted) VALUES (@FirstName,@MiddleName,@LastName,@IPv4Address,@DateInserted);select @@SCOPE_IDENTITY"
appdatasource.InsertParameters.Add("FirstName", fname.Text)
appdatasource.InsertParameters.Add("MiddleName", minit.Text)
appdatasource.InsertParameters.Add("LastName", lname.Text)
appdatasource.InsertParameters.Add("DateInserted", DateTime.Now())
appdatasource.InsertParameters.Add("IPv4Address", Request.UserHostAddress.ToString)
Dim appid As Integer = appdatasource.ExecuteScalar()
End Sub
I 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.
The scenario is that I wanna insert a record to the database via INSERT query and I need to user the identity number of this record in the INSERT query.
But I don't know how to achieve this.
Here is my table structure and code for your better understanding.
There are three columns in the Table: categoryID, categoryName, categoryPath. I need the path based on the categoryID which is an identity int column.
How do I set my insert identity return value parameter in codebehind? I have working code now but i have all of my parameters set in codebehindexcept the following:
Iam inserting ,updating in one DBfunction .i want to retrieve identityvalue when in insert.for that am adding select SCOPE_IDENTITY() in insert statement.how i can i get this value??
public int funAddEdit_rtblIncidentTypesDB(clsCM_Inc_IncidentTypesData objData, int actiontype) { string qry = ""; if (actiontype == 1) qry = "INSERT INTO _rtblIncidentType (cDescription,iEscGroupID,bAllowOverride,bRequireContract,iIncidentTypeGroupID,iWorkflowID,bAllowOverrideIncidentType,bPOIncidentType,cDefaultOutline) VALUES ('" + objData.cDescription + "'," + objData.iEscGroupID + ",'" + objData.bAllowOverride + "','" + objData.bRequireContract + "'," + objData.iIncidentTypeGroupID + "," + objData.iWorkflowID + ",'" + objData.bAllowOverrideIncidentType + "','" + objData.bPOIncidentType + "','" + objData.cDefaultOutline + "'); select SCOPE_IDENTITY() "; else if (actiontype == 2) qry = "UPDATE _rtblIncidentType SET cDescription='" + objData.cDescription + "' WHERE idIncidentType=" + objData.idIncidentType; int result = SqlHelper.ExecuteNonQuery(clsHelper.ConnectionString.ToString(), CommandType.Text, qry); return result; }
if i exceute the above query individually,it returns iddentity value,,bt unable to retireve the value in codebehind.
Basically i deal with two tables.i have a table T1 of the following format:id company_name i need to read this data and create a table T2 as followsi wrote the following code. it worked fine for retrieving data and modification but fails to insert the modified data into the 2nd table.the error is, it does not recognise the value for @token
ArrayList dynarr=new ArrayList(); // global variable protected void Button2_Click(object sender, EventArgs e) { int row = 1; int i; string strcmd = null; string Connection = "Data Source=...."; SqlConnection conn = new SqlConnection(Connection); string str = "select company_name from T1 where ID=@ID"; [code]...
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.
Cannot insert explicit value for identity column in table 'UserDetails' when IDENTITY_INSERT is set to OFF.
I'm trying to insert a record through a BLL (Business Logic Layer) class with an 'Insert' button attached to the FooterTemplate of a GridView2. My code:
[Code]....
[Code]....
BLL layer code:
[Code]....
The field 'idUser' is autoincremented. When I use SqlDataSource with a DetailsView, add option it adds a record and autoincrements the 'isUser'.
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 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'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.
I've been self teaching SQL and asp.net and i'm a little stuck. I have a stored proc for the insert and then in my Insert inside my class it's not returning the ID after the insert as I am receiving an error message that NULL value has cannot be inserted. I want to add default values to a seperate table after the insert. I will provide my code below, if anyone can help me why the value is not going across?
Resetting IDENTITY column to a new valueDuring application development we always entry some test data also our tester test with test data and as a result if the table contains IDENTITY columns( specially ID column) which incremented to the number of data already entered.
However, when the application goes running with real data to the client and the client want his ID values from starting 1, then we need to RESEED the value of the IDENTITY column of the table after clearing all data. This can be done as bellows:
DBCC CHECKIDENT (TableName, RESEED, 0)
However, can be reseed with any values instead of zero(0) in the above statement.
I have an identity column that increment by 1 on every insert. I have deleted all the rows using delete query but the identity coulumn is still not reseting to zero, how do i reset it, as it was when the table was first created.
I have created small database prods. I have created one table Products. I have given columns like productid, productname, price. after creating table. I got an idea to add identity to productid ie., auto increment. how to add identity to existing column.
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 was wondering how I could use user.identity in a where statement in sqldatasource to return results for a user profile. I already have a table that stores the username. Just need to return it's results.
I tried all that was suggested in the above link..but I just cannot see the Identity data type option in the drop down. How can I set one field as a Identity data type if I dont see it?
