Try this:

SQL

DECLARE @cols NVARCHAR(200)
DECLARE @dt NVARCHAR(1000)
DECLARE @pt NVARCHAR(2000)

SET @cols = STUFF((SELECT DISTINCT '],[' + F
					FROM YourDataBase 
					ORDER BY '],[' + F
			FOR XML PATH('')),1,2,'') + ']'

SET @dt = 'SELECT * ' +
        'FROM YourTable'

SET @pt = 'SELECT ID, ' + @cols + ' ' +
        'FROM (' + @dt + ') AS DT ' +
        'PIVOT(MAX(F) FOR(ID) IN (' + @cols + ')) AS PT ' +
        'ORDER BY ID'
EXEC (@pt)
