I understand distinction. In my case the column is Primary key. But I want to make it an Identity (in code) (if not yet identity).
Thank you.

>One thing you need to keep in mind. Identity is not PrimaryKey and can have duplicates. If you want the column to be a PK, you need to set that after making it Identity.

>>On the last point, I do want to preserve the current value in the column before making it an identity. From this point, the column value will be incremented then. So I do not want to recreate the table.

>>Thank you for your help.
