I have a table similar to below :

id | column1 | column2 | column3
1  | values  | values  | values
2  | values  | values  | values
5  | values  | values  | values
6  | values  | values  | values
7  | values  | values  | values
9  | values  | values  | values

I want to copy this table into excel and modify the table and paste back into sql server.

However, when I do that the id values changes to 10, 11, 12 etc. as below :

id  | column1 | column2 | column3
10  | values  | values  | values
11   | values  | values  | values
12   | values  | values  | values
13   | values  | values  | values
14   | values  | values  | values
15   | values  | values  | values

Is it possible that id remains the same when I paste it from excel?

Likely this is happening because the id column has the identity property. When you paste back are you replacing the existing data, or adding new rows? If you are adding new rows, assuming that my assumption about identity column is correct, the identity values will increase.

Look at the DDL for the table (and post it if you like), which will tell us more. You can see how to get the DDL here: http://weblogs.sqlteam.com/brettk/archive/2005/05/25/5276.aspx

if you want to preserve the identity values, you can use IDENTITY_INSERT ON. But for that the original records should not exist anymore. Otherwise it will break the uniqueness of the column.
