I'm trying to create a table that uses some sort of timestamp as the ID column with PK. The goal is to create a table that can be sorted using the ID column which can be used to order the table using a numbering format searching according to the date and time the data was inserted. I know I can set the ID column using identity but I would like the column to be more useful. I'm hoping there is an efficient way of doing this which provides a performance gain. E.G. I know in excel you can put a date/time into a cell and it displays as a number depending on the format used.
Hope this is clear, I'm finding it hard to explain. Thanks,
