[dba-SQLServer] Strange happening

If order by is ignored in a view without a TOP, why is a TOP considered bad
form?  It sounds like a REQUIREMENT.

Order by is ignored in a view unless is has a top. The Top 100 percent trick
works in some versions but not all versions (sp versions) of SQL Server.
Using the top 100 percent trick to force an order by in a view is considered
a bad practice.

I think that you could modify the index to include the NewID() column as
Stuart suggested, and get the results you want. Alternatively, SELECT TOP n
* FROM yourView ORDER BY NewID().
