SQL Row_Number() function in Where Clause without ORDER BY?

Question

I found a bunch of questions on this topic with nice solutions but none of them actually deal with what to do if the data is not to be ordered in one specific way. For insta

Answer 1

The real problem with the approach that you are proposing is that order in the db is not guaranteed. It may coincidentally be returning to your application in the same order all of the time, but the SQL Standard guarantees no such order and may change depending on version or edition changes. The order of data from a SQL Server is not guaranteed without an order by clause. This design would be one that simply relies on 'luck.' If this possible variation in order has an impact on your implementation, you may want to change it now before you get too far into the implementation.
