Concatenate strings from different rows

Hello.

I have a table like:

Id Name Description OrderId
1 Microsoft This is a 0
1 Microsoft huge company. 1

I need to create a select query that will concatenate description for both entries and output it like

Microsoft - This is a huge company.

Try using the USE XML PATH () as part of the select statement; maybe something like:

Code Snippet

declare @.testData table
( id integer,
[Name] varchar(10),
Description varchar(15),
orderId integer
)
insert into @.testData
select 1, 'Microsoft', 'This is a', 0 union all
select 1, 'Microsoft', 'huge company.', 1

select distinct
[Name] + ' - ' +
( select description + ' ' as [text()]
from @.testData b
where a.id = b.id
order by orderId
for xml path ('')
) as outputString
from @.testData a

/*
outputString
--
Microsoft - This is a huge company.
