sql - Multiple Counts Over Multiple Dates -


i doing following query (edited):

select count(orders) orders_table order_open_date<=##/##/#### , order_close_date>=##/##/####

where ##/##/##### same date. in essence number of 'open' orders given day. wanting same count every single day year , don't want write separate query each day whole year. i'm sorry simple new sql , guess don't know how search answer question since searches have come nothing. can offer.

why not

select order_date, count(orders) orders_table group order_date

and last year

select order_date, count(orders) orders_table order_date > date_sub(curdate(), interval 1 year) group order_date;
