Error Number: 1055
Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'v10.haberler.tarih' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
SELECT Year(`tarih`) as yil, Month(`tarih`) as ay, Count(*) As habersayisi FROM haberler WHERE onay=1 GROUP BY Year(`tarih`), Month(`tarih`) order by tarih desc
