Question

I have some minor problem with an SQL query. I have to select data from multiple tables like:

offers:

| id | offer      | info  
| 1  | City break | information

pictures:

| id | id_offer | picture_name  | title  
| 1  | 1        | bucharest.jpg | Bucharest  
| 2  | 1        | london.jpg    | London

sql query:

SELECT offers.* as t1, pictures.* as t2
FROM offers  
JOIN t2 ON t1.id=t2.id_offer  
WHERE t1.id = '1'

The code is much larger but I don’t understand how to wrap results from t2 into an array. Because the length of the array returned is made by t2 which is the pictures table. This will return an array with 2 objects.

It is possible to return one object in the array with both pictures in it?

Answer 1

MySQL does not support array datatypes.

You can return a comma separated list of values instead:

SELECT  o.*, GROUP_CONCAT(picture_name ORDER BY p.id)
FROM    offers o
JOIN    pictures p
ON      p.id_offer = o.id
GROUP BY
        o.id
