Distinct Query On One Column

Posted on By David Kittell

While this query has more than what may be needed this will help you to get data based on one unique column.

SELECT [File Name]
	,[Division]
	,[Version]
FROM (
	SELECT [File Name]
		,[Division]
		,[Version]
		,row_number() OVER (
			PARTITION BY [Division] ORDER BY [Version] DESC
			) AS RowNumber
	FROM <DatabaseTableName>
	) AS A
WHERE a.RowNumber = 1
	AND (
		[Version] LIKE '%2014%'
		OR [Version] LIKE '%2013%'
		)
