Execution Plan and Results of Aggregate Concatenation Queries Depend Upon Expression Location
The best practice is to avoid the usage of function in ORDER BY clause when string concatenation operations are executed.
The reason for this behavior is that the use of function in ORDER BY clause will change the order of query execution and create an unexpected output.

COUNT(*) Not Allowed but COUNT_BIG(*) Allowed – Limitation of the View 5
One of the most prominent limitations of the View it is that it does not support COUNT(*); however, it can support COUNT_BIG(*) operator. In the following case, you see that if View has COUNT (*) in it already, it cannot have a clustered index on it. On the other hand, a similar index would be created if we change the COUNT (*) to COUNT_BIG (*).For an easier understanding of this topic, let us see the example in blog.
I have put up a quick guide here where I am writing all the 14 new functions linking them to my blog post as well Book On-Line for a quick reference.

SSMS Automatically Generates TOP (100) PERCENT in Query Designer
Question: I am trying to create a view in Query Designer (not in the New Query Window). Every time I am trying to create a view it always adds TOP (100) PERCENT automatically on the T-SQL script. No matter what I do, it always automatically adds the TOP (100) PERCENT to the script. I have attempted to copy paste from notepad, build a query and a few other things – there is no success. I am really not sure what I am doing wrong with Query Designer.
Why following code when executed in SSMS displays result as a * (Star)?
