Question

If possible I would like to increment a number on the application side and save to the database using c# and Linq.

So for example I have a table like so:

|id|text|version|
-----------------
 1  hello   1
 2  hello   1

When inserting a new record into this table I want to get the current version number and increment by 1 then insert a new row

|id|text|version|
-----------------
 1  hello   1
 2  hello   1
 1  hello   2

I can do a standard insert using linq but obviously stuck with what to do with the version

DataContext db = new DataContext

using (db)
{
    table t = new table
      {
         text = TextBox1.Text
         version = ??
      };

db.table.InsertOnSubmit(t);
db.SubmitChanges();
}

Can I somehow select the row and get the current version number and then just increment by 1? Or should I just re-think my approach?

Thanks

I had the liberty to change the database structure so I just used IDENTITY col.
