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.

You can use the following method:

select
STUFF(
        (
        select ', ' + CONVERT(varchar(10), ID) FROM @temp
        where ID<50
group by ID for xml path('')
        ), 1, 2, '') as IDs

Implementation:

Declare @temp Table(
ID int
)
insert into @temp
(ID)
values
(1)
insert into @temp
(ID)
values
(3)
insert into @temp
(ID)
values
(5)
insert into @temp
(ID)
values
(9)

 select
STUFF(
        (
        select ', ' + CONVERT(varchar(10), ID) FROM @temp
        where ID<50
group by ID for xml path('')
        ), 1, 2, '') as IDs

Result will be:
