SQL Server convert select a column and convert it to a string

Question

Is it possible to write a statement that selects a column from a table and converts the results to a string?

Ideally I would want to have comma separated values.

Answer 1

select  stuff(list,1,1,'')
from    (
        select  ',' + cast(col1 as varchar(16)) as [text()]
        from    YourTable
        for     xml path('')
        ) as Sub(list)
