To find the longest string in a column in SQL Server, you can use the LEN function to get the length of each string and then use ORDER BY in combination with TOP 1 to retrieve the longest string. 

Here's how you can write the query:

Example 1

-- Technique 1
SELECT TOP 1 [Description]
FROM
    Article
ORDER BY
    LEN([Description]) DESC;

Example 2

-- Technique 2
SELECT TOP 1 [Description], LEN([Description]) AS length_of_string
FROM
    Article
ORDER BY
    length_of_string DESC;

Example 3

-- Technique 3
select top 1 * 
from (
	select [Description], LEN([Description]) AS [S_Length] from Article
) AS Article
order by [S_Length] desc

Example 4

-- Technique 4
select top 1 * 
from (
	select 
	[Description], 
	LEN([Description]) AS [S_Length],
	ROW_NUMBER() OVER( ORDER BY LEN([Description]) DESC) AS ROWNO
	from Article
) AS Article
