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:

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 want to query '2' using LINQ C# to the table in MS SQL and show the record which i have done easily BUT now i want to get the next auto incremented value to make Next button on the sane web form, which is in this case is '4' and i also want the previous imageId as well.
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

View 12 RepliesI 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
