  Rename 'mytable' as appropriate:

  SELECT DateDay,

  STUFF((SELECT ',' + CAST(SP2.ID AS VARCHAR(10)) FROM dbo.mytable SP2

  WHERE SP2.DateDay = SP1.DateDay FOR XML Path('')), 1, 1, '') ID

  FROM dbo.mytable SP1

  GROUP BY SP1.DateDay

  You could alternatively create a function to handle it if this is part of a larger query.
