从mysql中的多个表中检索值

Question

I am using php and I have to get the data from multiple tables with common id, but the problem is that in few tables that common id contains multiple records,using inner join gives me separate rows of data eg

{"dish_id":"52","quantity":"1","STATUS":"pending","franchise_id":"5","order_type":"PickUp","extraId":"2"}
    {"dish_id":"52","quantity":"1","STATUS":"pending","franchise_id":"5","order_type":"PickUp","extraId":"3"}

extraId is the multiple record for the dish_id:52. I need result like this.

{"dish_id":"52","quantity":"1","STATUS":"pending","franchise_id":"5","order_type":"PickUp","extraId"[{"id":"2"},{"id":"3"]}}

My query is:

 $orders =  "Select DISTINCT order_detail.dish_id,order_detail.quantity,order_detail.STATUS,
order_main.franchise_id,order_main.order_type,
order_extras.extra_id,order_extras.extra_title,
order_addons.addon_id,order_addons.addon_size 
from order_main 
INNER JOIN order_detail ON order_main.id=order_detail.order_id 
INNER JOIN order_extras ON order_main.id=order_extras.order_id 
INNER JOIN order_addons ON order_main.id=order_addons.order_id 
WHERE order_main.franchise_id='$storeId' 
and 
order_detail.STATUS!='$order_status'";

please help.

Answer 1

Use group by and group_concat . Something like this:

Select d.dish_id, d.quantity, d.STATUS, m.franchise_id, m.order_type,
       group_concat(e.extra_id) as extraids
from order_main m INNER JOIN
     order_detail d
     ON m.id = d.order_id INNER JOIN
     order_extras e
     ON m.id = e.order_id INNER JOIN
     order_addons a
     ON m.id = a.order_id 
where m.franchise_id = '$storeId' and d.STATUS <> '$order_status'
group by d.dish_id, d.quantity, d.STATUS, m.franchise_id, m.order_type;

Your desired results do not include these columns:

• e.extra_title
• a.addon_id
• a.addon_size

I would also suggest that you remove the join to order_addons .

Notice that table aliases make the query easier to write and to read.

You can use group by with dish_id

$orders =  "Select DISTINCT order_detail.dish_id,order_detail.quantity,order_detail.STATUS,
order_main.franchise_id,order_main.order_type,
order_extras.extra_id,order_extras.extra_title,
order_addons.addon_id,order_addons.addon_size 
from order_main 
INNER JOIN order_detail ON order_main.id=order_detail.order_id 
INNER JOIN order_extras ON order_main.id=order_extras.order_id 
INNER JOIN order_addons ON order_main.id=order_addons.order_id 
WHERE order_main.franchise_id='$storeId' 
 and 
order_detail.STATUS!='$order_status' group by order_detail.dish_id";
