Fetching data from Two tables using Range

Question

I have Two tables, Tour table and Tour Dates table.

1. tours Table
   • Id
   • tour_title

Here's a link of table to view tour table!

2. tour_dates Table
   • id
   • tour_id
   • price

Here's a link of table to view tour_date table!

Now I am using filter of price range like

• From $10 to $50
• From $50 to $80
• From $80 to $100

I have tried lots of different queries of join and even tried for nested query like this one.

$qry = "SELECT * FROM `tours` WHERE status='1' ";
$qry1 = mysqli_query($con,$qry);
while($data = mysqli_fetch_array($qry1)){

$qfilter = "SELECT * FROM `tour_dates` WHERE tour_id='".$data['id']."' AND (`price` BETWEEN 10 AND 50) ORDER BY price DESC ";
    $qfilter1 = mysqli_query($con,$qfilter);
    $tour_ob = mysqli_fetch_object($qfilter1);
    $num = mysqli_num_rows($qfilter1);
    if($num>0){ 
     ------
      }
    }

Please provide any solution. thank you.

Answer 1

You can use joins to get data from both tables.

select t1.id,t1.tour_title,t2.price  
from tours t1 inner join tour_dates t2 on t1.id=t2.tour_id 
where t1.id=tour_id and (t2.price between 10 and 50) order by t2.price desc

You can write stored procedure which will handle your dynamic where conditions.

CREATE PROCEDURE `procedure_name` (in in_condition varchar(1000))
BEGIN
      set @query='select t1.id,t1.tour_title,t2.price  
                  from tours t1 inner join tour_dates t2 on t1.id=t2.tour_id 
                  where t1.id=tour_id ';

       set @query=concat(@query,' and ',in_condition,' order by t2.price desc');

        prepare stmt from @query;
        execute stmt;
        deallocate prepare stmt;
END
