i want filter items based on 2 different dates using mysql. in database store data 2017-03-28 10:55:10 . need date part, not time used date() function: select sum(cashamount) sumcashsalesamount, date(transactiondate) datepart master_transaction transactiondate between '2017-02-22%' , '2017-03-28%' order transactiondate desc above query have 2 dates 2017-02-22% , 2017-03-28% return no result. but when change 2017-03-28% date 2017-03-29% (tomorrow date) results. don't use between "dates". put in quotes, because values datetime values. the best way write condition is: where transactiondate >= '2017-02-22' , transactiondate < '2017-03-29' note inequality second condition. between inclusive, include midnight on 2017-03-28. why best? it allows query optimizer take advantage of indexes , partitions. it logic want. it works both date , datetime types.
