Using MySQL how do I select data between two dates if the dates are in separate columns -


in database, have column check-in date , column check-out date. need select every row has check-in date <= 7/30/2017 , check-out date >= 7/30/2017.

this code have now:

select *  `v_reservation_records`  cast(checkin date) <= '7/30/2017'  , cast(checkout date) >= '7/30/2017'

here example date db:

2018-09-18

when run query, not results, know have check-in date equal 7/30/2017. missing? or there easier way accomplish goal?

assuming casting valid values date
should convert literal date 

select *  `v_reservation_records`  cast(checkin date) <= str_to_date('7/30/2017' , '%d/%m/%y') , cast(checkout date) >= str_to_date('7/30/2017' , '%d/%m/%y')

and can use between 

select *  `v_reservation_records`  str_to_date('7/30/2017','%d/%m/%y')          between cast(checkin date) , cast(checkout date)
