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:
[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 am trying to set up an insert command in vb for sql server (not mysql). the following works fine as long as I manually enter a new ASSalesId and don't have this field auto increment. this field is set up a a primary key. I would like to just use auto increment on this field. but every time I set the field to auto increment the insert fails. if I just remove the reference to this field from the statement the insert fails.

I got a table PartsMedia where I can insert all the images related to a product. The table has the columns :
PartsMediaID , auto-increment
PartsNo
MediaLink
MediaDescription
CatalogCode
SortCode
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')

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

I'm trying to get an IDENTITY column to auto-increment with each new row inserted, so that the field (userid in this case) can be used as a unique identifier.
However, I'm getting this error:
[Code]....
My code looks like this:
[Code]....
I don't understand - if I have to explicitly insert something into my auto-increment column, how do I know what to insert? Isn't the point of an auto-increment column that it's... auto?

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.

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.

So 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:
[Code]....
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.
