I 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 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 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 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 am having a table named Invoices.From that table I want everything the newly inserted and updated rows from that table.

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

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.
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.
I have a FileSystem based asp.net 2.0 app that uses Sql Server 2005 Express database.
I have only one dataset for this app with only 4 tables. After i have completed it to a part, a co-worker have added some Classes to it, which are not in same namespace of myBLL classes.
Then i tried added a new table to the dataset. It like all other tables in that dataset uses SQL Statements to access and manage data.
The problem started after i added that new table. I cannot access it from code. I can access all previous TableAdapters but not this new one.
I've editing a create user wizard to add a 2nd step, this step will collect the users address. i can't get the second step to save into a table. I'm completely new to visual web developer, so if you reply please make it as jargon free as possible, see source code and vb code, i think i'm missing code for the "finish Button click"

I am using SqlCommand to insert new value to a table. My table has 2 fileds1. IDDT (Auto increment) (numaric)2. Name (VARCHAR)i am runing below code to insert new value
[Code]....
Acording to the table the IDDT value will be inserted automatically. I need to get that value using above code.
I've been searching on the internet about this issue but all studies returns a ID value that is integer. However, in my system primary key field is a GUID, I mean uniqueidentifier. How can I get this value? Should I use SELECT SCOPE_IDENTITY() which is integer ?
View 2 RepliesI 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 am trying to insert some string values into database.
The problem here is that, the string is truncated without warning..
Here is my vb.net code
[Code]....
And here is how I declared the varible in stored procedure
[Code]....
And If I insert "myCode01234567890" then it's truncated without warning at all.
How can I let it throw an exception rather then truncate the string without any warnings ?
Im using Objectivation as a DAL with GridView !
I would like to link item when i create it with the InsertMethode :
I have this 2 table :
Item ( id, name )
ItemRelation( idrelation, idParentItem, idSonItem)
I have a page with a gridview with the liste of item in relation with another item (Same table) : Select * From Item where id IN ( Select idSonItem where idParentItem = @TheItem )
When i add an item from this grid i would like to link it with the current Item : So I insert the Item with the GridView InsertMethod then I do another Query an the ItemRelation with idParentItem as the courant Item and the Inserted Item as the idSonsItem !
so the question is : How to get the id of an inserted Item after i get executed the InsertMethod ?
I have this image upload code...that works....but I need a code to get the Id of the image that i just uploaded..

I've done a lot of searching on this here but I can't seem to find anyone who has done this. I'm sure it's a common problem but I can't figure out the right keywords to search for the solution so I'm sorry if this is a duplicate.I have a dataset where I've used the Generate Insert, Update, and Delete statements as well as the Refresh the Data Table options so that I can retrieve the last inserted ID when I'm using an ObjectDatasource.however, when I'm handling the ObjectDataSource-Inserted method, I'm getting a 1 as a return value, which I assume is the affected rows. I don't want that, I want the ID so that I can use it in my code.I looked at the generated code for the insert method and it is doing a SELECT after inserting, but it returns the whole row not the ID, so how can I get at this row to retrieve the value?
View 6 RepliesI 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 would like the ObjectDatasource insert and update data methods to return the inserted or updated object like LinqDataSource do.
View 2 RepliesI 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 made one window base application in VS2008 (VB.net). i made one simple code where i can insert data.and after inserting i can see that data on grid.when i am inserting data insert query runs perfect.after that for debugging purpose i fire select query and get result in dataset and its show data too.but when go
into database my inserted data not showing there.
