T-SQL Nested Subquery - tsql

Question

I want to place this working code within a SQL Statement, OR do I need to perform a UDF.
The result set is a one line concatenation, and I want it to be place in every one of the overall result set lines.

Not really sure what you are asking for but you can doing something along the lines of
Select col1 + ', ' + col2 + ', ' + col3 etc....
