A few minutes after you asked this question, Mark gave you a very good answer: group by day: GROUP BY CAST(m.messzeit AS DATE) or less efficient: GROUP BY EXTRACT(YEAR from m.messzeit), (EXTRACT(month FROM m.messzeit), EXTRACT(day from m.messzeit) or if you want to group by month in year: GROUP BY EXTRACT(YEAR from m.messzeit), (EXTRACT(month FROM m.messzeit) Mark ------------------------------------ ------------------------------------ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Visit http://www.firebirdsql.org and click the Documentation item on the main (top) menu.
