Make SELECT subquery COUNT the total subscribers of a subscriber - sql

Question

I trying to create a query that counts the total subscribers of a subscriber. It currently looks like this:
await this.queryInstance.query(
'SELECT all_users_subbed_to.* , (SELECT COUNT(??????)) AS subscribers_sub_count
FROM
(SELECT publisher_id, subscriber_id, u2.username
AS username, u2.user_photo AS user_photo
FROM subscribers s
INNER JOIN users u
ON (u.id = s.subscriber_id)
INNER JOIN users u2 ON (u2.id = s.publisher_id)
WHERE subscriber_id = ($1)
LIMIT 20
OFFSET ($2))
AS all_users_subbed_to;'
,
[currentUserId = 80, offset]
);
The FROM CLAUSE AKA all_users_subbed_to is WORKING correctly and displays a ALL the subscribers the current user has. The data comes back as this:
"subscribedToCurrentUser": [
{
"publisher_id": 84,
"subscriber_id": 80,
"username": "supercoookie",
"user_photo": "profile-pic-for-supercoookie.jpeg"
},
{
"publisher_id": 88,
"subscriber_id": 80,
"username": "GERPAL1",
"user_photo": "profile-pic-for-GERPAL1.jpeg"
}
]
The issue I am having is getting the total subscriber counts for the list of those subscribers. I need to use the subscribers publisher_id ie all_users_subbed_to.publisher_id and get their total subs (using COUNT) from the subscribers table. I would like to create a new column called have subscribers_sub_count that contains that total.
Any ideas?
It should look like this:
"subscribedToCurrentUser": [
{
"publisher_id": 84,
"subscriber_id": 80,
"username": "supercoookie",
"user_photo": "profile-pic-for-supercoookie.jpeg",
"subscribers_sub_count": 3
},
{
"publisher_id": 88,
"subscriber_id": 80,
"username": "GERPAL1",
"user_photo": "profile-pic-for-GERPAL1.jpeg",
"subscribers_sub_count": 70
}
]
The subscribers table looks like this:

Answer 1

await this.queryInstance.query(
'SELECT all_users_subbed_to.*, COUNT(all_users_subbed_to.id) AS subscribers_sub_count
FROM
(SELECT publisher_id, subscriber_id, u2.username
AS username, u2.user_photo AS user_photo
FROM subscribers s
INNER JOIN users u
ON (u.id = s.subscriber_id)
INNER JOIN users u2 ON (u2.id = s.publisher_id)
WHERE subscriber_id = ($1)
LIMIT 20
OFFSET ($2))
AS all_users_subbed_to;'
,
[currentUserId = 80, offset]
);

Answer 2

Fixed it. It just needed a WHERE clause that used data from all_users_subbed_to
await this.queryInstance.query(
'SELECT all_users_subbed_to.* ,
(SELECT COUNT(*) FROM subscribers s2 WHERE s2.publisher_id = all_users_subbed_to.publisher_id) AS subscribers_sub_count AS subscribers_sub_count
FROM
(SELECT publisher_id, subscriber_id, u2.username
AS username, u2.user_photo AS user_photo
FROM subscribers s
INNER JOIN users u
ON (u.id = s.subscriber_id)
INNER JOIN users u2 ON (u2.id = s.publisher_id)
WHERE subscriber_id = ($1)
LIMIT 20
OFFSET ($2))
AS all_users_subbed_to;'
,
[currentUserId = 80, offset]
);
