I have query

SELECT
    availability.shop_id,
    shops.name

FROM availability

LEFT JOIN shops
ON availability.shop_id=shops.id 

WHERE
fruit_id = 2

As a result I get name list of shops where fruit with id 2 (apple) is available.

What should I do so that I can include shop_activity table in query to get user's status if users.id = 1 beside proper shop. Something like this...

Shop1, NULL
Shop2, status: 1

You could try something like this:

SELECT
    availability.shop_id,
    shops.name,
     shop_activity.status
FROM availability
LEFT JOIN shops
ON availability.shop_id=shops.id 
LEFT JOIN shop_activity
ON shop_activity.shop_id = availability.shop_id
   and shop_activity.user_id = 1
WHERE
fruit_id = 2

SELECT
    availability.shop_id,
    shops.name

FROM shops 
LEFT JOIN availability ON availability.shop_id=shops.id 
LEFT JOIN shop_activity ON shop_activity .shop_id=shops.id
WHERE
fruit_id = 2
and users.id=1

try making shops as the first table in left join

Try the following:

SELECT shops.name, shop_activity.status
FROM shops
    INNER JOIN availability ON availability.shop_id = shops.id
        AND availability.fruit_id = 2
    LEFT JOIN shop_activity ON shops.shop_id = shop_activity.shop_id
        AND shop_activity.user_id = 1

This should give you a row for every shop with apples, but the status will show as null for shops where the user has no activity, otherwise shows the status of that user.
