Column not found: 1054 Unknown column '2' in 'on clause' - InnerJoin query not working properly - sql

Question

I am trying to execute the following code, the error applies to the $waitingToBeShipped... section of the code. As you can see I am using an innerJoin. I want to retrieve all of the rows that have orders containing products that are still waiting to be shipped.
public function destroyMany($ids) {
$status = false;
$ids = explode(",", $ids);
foreach ($ids as $id) {
$innerJoin = OrderDetails::where('product_id', $id)->pluck('order_id');
if ($innerJoin->count()) {
$innerJoin = preg_replace("/[^A-Za-z0-9\-]/", '', $innerJoin);
Log::info($innerJoin);
}
$waitingToBeShipped = Order::where('is_delivered', 0)
->join('order_details', 'orders.id', '=', $innerJoin)
->get();
}
}
But it returns:
local.ERROR: SQLSTATE[42S22]: Column not found: 1054 Unknown column '2' in 'on clause' (SQL: select * from `orders` inner join `order_details` on `orders`.`id` = `2` where `is_delivered` = 0 and `orders`.`deleted_at` is null)
I've tried to run this query manually in PHPMyAdmin, which also gives an error with the literal query that I just copied, BUT, when I remove the backticks around the number 2, it does actually give me a result.
I am not sure how I can do the same for my code? Any help would be appreciated, thanks!

The fix to this is to change the query to:
public function destroyMany($ids) {
$status = false;
$ids = explode(",", $ids);
foreach ($ids as $id) {
$innerJoin = OrderDetails::where('product_id', $id)->pluck('order_id');
if ($innerJoin->count()) {
$innerJoin = preg_replace("/[^A-Za-z0-9\-]/", '', $innerJoin);
Log::info($innerJoin);
}
$waitingToBeShipped = Order::where('is_delivered', 0)
->join('order_details', 'orders.id', '=', 'order_details.order_id')
->where('order_details.order_id', $innerJoin)
->get();
}
}
