Answer 1

您可以在查询中使用BETWEEN

select * from inventory left join product on product.productid=inventory.productid where inventory_date BETWEEN CAST('$startdate' AS DATE) AND CAST('$enddate' AS DATE) order by inventory_date desc

Answer 2

Check your inventory_date field datatype is date or not and also it contain date or not.

Check $startdate and $enddate is contain date with yyyy-mm-dd format.

$sql = "select * from inventory
            left join product on product.productid=inventory.productid
            where
            date(inventory_date) BETWEEN ".$startdate." AND ".$enddate." order by inventory_date desc";
