Question: Is it possible to add an auto incremental identity column to any table in SQL Server after creating a table.

Answer: There are two answers – No and Yes. Let us see them one by one.

Answer No – If you have an integer column in your table and you want to convert that column to identity table. It is not possible with the help of SQL Server. You will just have to add a new column.

Answer Yes – If you want to add new column to the table, it is totally possible to do so with the help of following a script.

  • This will provide you with the columns that have Identity insert on, but not the Key columns

  • Another method that works in all versions is

    select table_schema, table_name,column_name from information_schema.columns
    where columnproperty(object_id(table_name),column_name,’IsIdentity’)=1
    order by table_schema, table_name
