Question

I have 2 tables users, and products_users.

I want to get all users where their FBID as in a predetermined list…HOWEVER i also want to get the total count of how many times they appear in the products_users table… (this essentially shows how many different products a user “liked” on my site)

In the end I would want:

user1, 4
user2, 7
user3, 28
etc.

The issue is getting the count to work.

I have this currently:

select users.*
    , products_users.fbid
    , products_users.`graph_id` as objects_liked 
    from users 
        inner join products_users 
            on (products_users.`fbid` = users.fbid) 
            and products_users.`fbid` in ('0_fbid','1_fbid')

which results in the following:

However, instead I want each row to be a unique user and the objects_liked column to represent to TOTAL count.

Is there a way to do this? Please help!

FYI – I have already tried to change

products_users.`graph_id` as objects_liked

to

count(products_users.`graph_id`) as objects_liked

but that only results to:

Please help!

Answer 1

I find it a bit confusing how you are expecting to get user1, 4 user2, 7 user3, 28 etc. as a result and you’re selecting by users.*, products_users.fbid, products_users.graph_id. I assume the first result is the one you’re expecting to get.

The following query will show you the users and the amount of times they appear in the products_users table (I understand that is what you’re looking for). I’m guessing the users columns because you didn’t provide them.

select users.name, count(*) as count_of_rows_in_products_users_table from users
inner join products_users on (products_users.fbid = users.fbid)
where products_users.fbid in ('0_fbid', '1_fbid')
group by users.name

Hope that helps.
