Error Number: 1055
Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'lpa_impresa.ediciones.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
SELECT * FROM (`ediciones`) WHERE year(fecha) = '2015' AND month(fecha) = '03' AND `paginas` > 30 GROUP BY `edicion`
