[quote]Eugene Elutin (3/19/2013)
Are you sure that OP wants one column with all subjects concatenated?
If not, then he might want dynamic cross-tab:


SELECT  dow.[DAY],  s.[Subject], ROW_NUMBER() OVER (PARTITION BY dow.[DAY] ORDER BY s.[Subject]) SN
INTO #ds
FROM [DAYOFWEEK] AS dow
JOIN SubjectToStudy AS s
ON s.WeekId = dow.WeekId

DECLARE @sql NVARCHAR(2000) = '';
SELECT @sql = @sql + '
,MAX(CASE WHEN SN = ' + CAST(SN AS VARCHAR) + ' THEN [Subject] ELSE '''' END) AS Subject_' + CAST(SN AS VARCHAR)
FROM (SELECT DISTINCT SN FROM #ds) q ORDER BY SN
SET @SQL = 'SELECT [Day] ' + @SQL + ' FROM #ds GROUP BY [Day] ORDER BY [Day] '

EXEC (@sql)



Brilliant stuff.. well doneCool
