C# - Inserting Row Into Table With Auto Increment Value?

Mar 23, 2011

I got a table PartsMedia where I can insert all the images related to a product. The table has the columns :

PartsMediaID , auto-increment

I want to insert a complete row with automatic increment and the PartsNo should be the same as the PartsNo from the PartsMaster table.

The medialink should be the PartsNo + '-2.jpg'
The mediadescription is for example 'image2'
The CatalogCode should be 'catalog'
and the sorting code should be '0'

From The partsMaster table I Just need the PartNo So I can add this to the PartMedia Table. The PartNo is the foreign key in the PartMedia table.

The following I got so far but no luck

insert into dbo.PartsMedia (PartNo,MediaLink,MediaDescription,CatalogCode, SortCode)
values (dbo.PartsMaster.PartNo, PartsMaster.PartNo+'-2.jpg','image2', 'catalog','0')

DataSource Controls :: Obtain Inserted Table Row Identity With An Auto Increment Key

Feb 18, 2010

I 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:

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.

Auto Increment Feature In Database?

Nov 2, 2010

I use SQL Server and when I create a new table I make a specific field an auto increment
primary key. The problem is some people told me making the field an auto increment for the primary key means when deleting any record (they don't care about the auto increment field number) the field increases so at some point - if the type of my field is integer for example - the range of integer will be consumed totally and i will be in trouble.

So they tell me not to use this feature any more.The best solution is making this through the code by getting the max of my primary key then if the value does not exist the max will be 1 other wise max + 1.Any suggestions about this problem? Can I use the auto increment feature?I want also to know the cases which are not preferable to use auto increment ..and the alternatives...note :: this question is general not specific to any DBMS , i wanna to know is this true also for DBMSs like

How Do Auto Increment Build/version Number

Jul 24, 2009

I have read that you can simply change the assembly version number to 1.0.* and it will auto increment.

Then I read that doing so will cause all kinds of registry issues...

Here http://www.codeproject.com/KB/macros/Increment_Build_Number.aspx

He says to download a file to do this for you...

If anyone is currently doing this with no issues I would like your advice.

If you have had issues doing this I would like your warnings.

DataSource Controls :: How To Add A Column For Auto-increment

Dec 10, 2009

i am a beginner in using ASP.NET. I have this problem. Whenever i select the advanced options in configuring the sqldatasource, the Advanced SQL Generation Options are all greyed out/disabled. Now, i found out that the cause of this is because the table that i am trying to access doesnt have a primary key. the scenario is that the table already has data.

My question is, how do i put a column in asp.net, that can serve as the primary key for the table? I want to do this only in asp.net and not through using SSMS.

DataSource Controls :: How To Auto-increment Primary Key When Adding A New Row Using Update Method

Jul 26, 2007

I followed the ASP.net official tutorial to create a DAL & Business Logic Layer [URL]. I have a table with a int ID field. I wish to write a function to add a new entry into this table but have the ID field auto-increment.

The ID field is set as the Identity Column and has a Identity Increment & Seed of "1". If I manually go to the table and insert a new record leaving the ID value null it automatically increments. But if I create a C# function to add a new entry I get an error saying that the ID field can't be Null. Is there any way to use the Update method as shown on line 14 below to add a new entry but with it automatically incrementing?

I did create a function called InsertDevice that simply inserts the other fields using a SQL INSERT and it auto-increments fine, just wondering if there is a way to do it using the DataTable and the Update method?

Web Forms :: How To Auto Delete And Auto Create Table Data

Jun 6, 2010

I have a simple online web system where it possible for the visitors to "play around" with the system. They can like create categories and products and so forth. Everything they create are stored into a database.

What I want is to be able to reset this database with my default values (table data) every n hours.

So for example if we have a bunch of users that have played with the system and created new things. Then I want to be able to make some kode that deletes all data in the tables in this database and fill it with default data. The default data can come from a backup file, or another database with same tables structure or whatever.

I want this task to be done every day at 12 pm or every n hour.

Is this possible (by forexample scheduled webservice tasks or just something as long as it is simple).

DataSource Controls :: Get The Identity After Inserting A Record Into A Table Using The Table Adapater?

May 14, 2006

I cannot for the life of me get the Identity after inserting a record into a table using the Table Adapater.
I am using Text SQL Commands. I have configured the table adapter to "Refresh the Data Table" and the Insert SQL Command:

INSERT INTO [Item] ([name], [description]) VALUES (@name, @description);
SELECT itemId, name, description FROM Item WHERE (itemId = SCOPE_IDENTITY())

The Visual Studio generated Insert Method used the following to execute the InsertCommand

int returnValue = this.Adapter.InsertCommand.ExecuteNonQuery();
return returnValue;

This returns the number of rows affected.

I've tried changing it to: int returnValue = (int)this.Adapter.InsertCommand.ExecuteScalar();
however it returns null;

I've tried playing with the InsertCommand Parameters and creating a new parameter and setting it as a ReturnValue however this doesnt work either.

Forms Data Controls :: Error When Inserting Into Table - Cannot Insert Explicit Value For Identity Column In Table

Aug 11, 2010

I am working on a web app for an online photo album. It is the last project in Scott Mitchell's book: "ASP.Net 2.0 in 24 hours".

I am creating a page where users can enter new photo images. The functionality for uploading an image will come later. I am working on just inserting a new row into the Pictures table with an optional category, a required title and a required description.

I am getting an error when I try to insert a new row.

Here is a screenshot of the page with a shot of the dropdown list.

The Categories are user-specific. I am getting the correct values retrieved.


There are two pretty simple database tables involved here.

NOTE: The CategoryID and PIctureID are both autoincrement integer columns.


The page uses a DetailsView that uses a SqlDataSource that uses the Pictures table. (The DetailsView's Default Mode property is set to "Insert". The "Enable Inserting" checkbox is also checked.)

The dropdown list uses a dropdown control that uses a SqlDataSource that uses the Categories table.

When the "Insert" button is clicked the CategoryID value associated with selected (Category) Name on the dropdown list will be used along with the Title and Description values to insert a row in to the Pictures table. (If no Category value is selected, then a null value will be used for the CategoryID. This is OK because the CategoryID column in the Pictures table allows nulls.)

My problem is that I am getting this error:

Cannot insert explicit value for identity column in table 'Pictures' when IDENTITY_INSERT is set to OFF.

(FYI: I have the full version of both Visual Studio and SQL Server.)

Here is my source code for the page:

SQL Server :: Inserting Whole Data Table Into Another

Oct 22, 2010

If I create a data tabe in C# like so:

datatable t = new DataTable;
DataColum C1 = new DataColum;//ID column
//the same with column C2

Then I fill up the table with some data. Then the goal is to either insert this data or update data in an SQLtable in SQL. If the data is inserted, the ID column in t would be empty, if updated, it would not be. So in the insertion case, the sql query needs to make sure that unique IDs are assigned during insertion, in the update case, it just has to look for the right IDs.How to go about this? Asking because I am only familiar with updating and inserting single lines into a table. One could loop in C# over the datatable t of course and insert or update line by line, but this would probably be slow. Is there a way to write an SQL query like this somehow:

Insert Into SQLTable Values (@t)
And Update like this:
Update SQLTable SET ... Where C1 = @t.C1
Or something like that.
I know that SQL server can create automatic update and insert queries and that you can then type things in C# like


But, this has proven to be super slow on our server, for unknown reasons. I have asked on this forum and got some answers from experts, but was not able to srot out the problem. How can we write a custom SQL query that allow updating and inserting a whole table, instead of just one line at a time?
