Hi again If you have an unknown number of columnnames that you want to transpose then you can use dynamic SQL using PIVOT. Checkout this query DECLARE @cols AS NVARCHAR(MAX) @query AS NVARCHAR(MAX) select @cols = STUFF((SELECT '' + QUOTENAME( ColumnName ) from yourtable group by ColumnName  id order by id FOR XML PATH( '' ) TYPE ).value( '.'  'NVARCHAR(MAX)' )  1  1  '' ) set @query = 'SELECT ' + @cols + ' from ( select value ColumnName from yourtable ) x pivot ( max(value) for ColumnName in (' + @cols + ') ) p ' execute( @query ) See SQL Fiddle with Demo . for detail check the link http://stackoverflow.com/questions/15745042/efficiently-convert-rows-to-columns-in-sql-server
