Question

I have got date field in my foos table. So now I need to select all foos from date interval but comparing only month and day.

For example, I need to select all foos 10 days before and after 7 Jan 2012 -> 28 Dec - 17 Jan. Or week around 10 Jul 2009 -> 3 Jul - 17 Jul. It should select depending only on month and day through all years.

My raw and naive solution

SELECT b_date FROM foos 
  WHERE DAYOFYEAR(b_date) BETWEEN 
    DAYOFYEAR('2011-01-07' - INTERVAL 10 DAY) AND (DAYOFYEAR('2011-01-07' - INTERVAL 10 DAY) + 20)
  OR DAYOFYEAR(b_date) BETWEEN 
    (DAYOFYEAR('2011-01-07' + INTERVAL 10 DAY) - 20) AND DAYOFYEAR('2011-01-07' + INTERVAL 10 DAY)
  GROUP BY foos.id;

Answer 1

SELECT b_date FROM foos 
  WHERE DAYOFYEAR(b_date) BETWEEN 
    DAYOFYEAR('2011-01-07' - INTERVAL 10 DAY) AND (DAYOFYEAR('2011-01-07' - INTERVAL 10 DAY) + 21)
  OR DAYOFYEAR(b_date) BETWEEN 
    (DAYOFYEAR('2011-01-07' + INTERVAL 10 DAY) - 21) AND DAYOFYEAR('2011-01-07' + INTERVAL 10 DAY)
  GROUP BY foos.id;
