Subqueries in Laravel/Eloquent not working - php

Question

I am currently working on a Lumen based application and I am stuck on an Eloquent/Laravel query. What I am currently working on is this:
$min = $filter['min_spending']*100;
$query = User::isCustomer()
->with("interests")
->leftJoin("points_history", "points_history.user_id", "=", "users.id")
->leftJoin("collections", "collections.user_id", "=", "users.id")
->select("users.*",
DB::raw("(SELECT SUM(amount) FROM points_history
WHERE points_history.user_id = users.id
AND points_history.confirmed = true ) as total_points"),
DB::raw("(SELECT SUM(price) FROM collections
WHERE paid_at IS NOT NULL
AND refunded_at IS NULL
AND collections.user_id = users.id) as total_purchase"),
DB::raw("(SELECT SUM(collections.price)) as current_purchase"))
->where("total_purchase", ">=", $min);
// other relevant code here
$query->groupBy('users.id')->orderBy('users.created_at', 'desc');
However, when I try to get the result, I get this error:
{"error":"SQLSTATE[42S22]: Column not found: 1054 Unknown column 'total_purchase >=' in 'where clause' (SQL: select count(*) as aggregate from `users` left join `points_history` on `points_history`.`user_id` = `users`.`id` left join `collections` on `collections`.`user_id` = `users`.`id` where `users`.`deleted_at` is null and `role` = 2 and `total_purchase >=` = 200000 group by `users`.`id`)"}
The subqueries did not seem to register which is causing the problem (?) My desired SQL Statement is this:
SELECT users . *,
(SELECT
SUM(amount)
FROM
points_history
WHERE
points_history.user_id = users.id
AND points_history.confirmed = true) AS total_points, (SELECT
SUM(price)
FROM
collections
WHERE
paid_at IS NOT NULL
AND refunded_at IS NULL
AND collections.user_id = users.id) AS total_purchase, SUM(collections.price) AS current_purchase
from
users
left join
points_history ON points_history.user_id = users.id
left join
collections ON collections.user_id = users.id
where
users.deleted_at is null AND (SELECT
SUM(price)
FROM
collections
WHERE
paid_at IS NOT NULL
AND refunded_at IS NULL
AND collections.user_id = users.id) >= 200000
GROUP BY users.id
where 200000 is $min. Could anyone help me pinpoint what the problem is in my query so I can figure out how to fix it?

Answer 1

You should try this:
$min = $filter['min_spending']*100;
$query = User::isCustomer()
->with("interests")
->leftJoin("points_history", "points_history.user_id", "=", "users.id")
->leftJoin("collections", "collections.user_id", "=", "users.id")
->select("users.*",
DB::raw("(SELECT SUM(amount) FROM points_history
WHERE points_history.user_id = users.id
AND points_history.confirmed = true ) as total_points"),
DB::raw("(SELECT SUM(price) FROM collections
WHERE paid_at IS NOT NULL
AND refunded_at IS NULL
AND collections.user_id = users.id) as total_purchase"),
DB::raw("(SELECT SUM(collections.price)) as current_purchase"))
->where("total_purchase", '>=', $min);
// other relevant code here
$query->groupBy('users.id')->orderBy('users.created_at', 'desc');

Answer 2

->where("total_purchase",">=", $min);
In the quick view, you did not put "," in the last line

Answer 3

FIXED:
Apparently, SELECT does not take multiple args but it accepts an array
->select(["users.*",
DB::raw("(SELECT SUM(amount) FROM points_history
WHERE points_history.user_id = users.id
AND points_history.confirmed = true ) as total_points"),
DB::raw("(SELECT SUM(price) FROM collections
WHERE paid_at IS NOT NULL
AND refunded_at IS NULL
AND collections.user_id = users.id) as total_purchase"),
DB::raw("(SELECT SUM(collections.price)) as current_purchase")]
Also ended up changing the WHERE clause to
$query->whereRaw(DB::raw("(SELECT SUM(amount) FROM points_history
WHERE points_history.user_id = users.id
AND points_history.confirmed = true ) <= " . $max));
with a dot instead of a comma to concatenate to the query
