if statements different in queries. please use following query:

set @cnt=(select count(date) data id = 1111         , data_date >= '2016-01-24 00:00:00'         , data_date < '2016-01-25 00:00:00');  select if(@cnt = 24, min(parameter1), '')  parameter1,        if(@cnt = 24, max(parameter2), '')  parameter2         station_data station_id = 6216         , data_date >= '2016-01-24 00:00:00'         , data_date <  '2016-01-25 00:00:00';
