As others have mentioned, it's not a good idea to depend on the physical order of the database table. Relational tables are conceptually more like unordered sets than ordered lists. Assuming a certain physical order may lead to unpredictable results.

Sounds like what you need is a separate column that stores the user's preferred sort order. But you'll still need to do something in your query to display the results in that order.

It is possible to specify the physical order of records in a database by creating a clustered index, but that is not something you'd want to do on an arbitrary user-specified basis. And it may still lead to unexpected results.
