Hi everybody,I am new to sql, so please bear with me on what might be a simple thing!I've got a huge database (6 mil records)and I would need to add an autonumber column, having the data sorted by a specific column. As it seems, when adding an autonumber, with Identity function, I cannot actually sort the data by the column I need, but the numbering is allocated by an implicit order. I am working with SQL Server Management Studio.Thanks in advance |

First off, any sorting happens when you query the data and include an ORDER BY clause. Adding a new column to capture some ordering as a an integer is a waste of space. And, what would you do if a new role was inserted in the future.Also, 5 million rows is not really so very big. |
