Raghavan writes "Hi,

I have a database scripts which will create the tables in a database. For inserting the default values of the application which uses the database i have a xml data file.

On executing the scripts the database will have the default initial values. After inserting the data i want to make the columns of the tables to be identity, without losing any data.

How can this be done?

I use sql server 2000 and windows 2000 sp5
Thanx in advance"

You need to create another table with the structure that you want. Then move the data from your table into this table. Then drop your table. Then rename the new table to the old one's name. Then add the constraints and everything else that you need.
