Create subquery in NOT IN - php

Question

I am using Laravel Framework 6.16.0.
I have the following sql query:
SELECT DISTINCT
`companies`.*
FROM
`companies`
LEFT JOIN `trx` ON `trx`.`companies_id` = `companies`.`id`
WHERE
`trx`.`transaction_date` >= 2020-11-12 AND companies.symbol NOT IN (SELECT DISTINCT
companies.symbol
FROM
`companies`
LEFT JOIN articles a ON a.companies_id = companies.id
WHERE
a.created_at >= 2020-11-12
ORDER BY
created_at
DESC)
ORDER BY
transaction_date
DESC
I have created the following eloquent query:
DB::connection('mysql_prod')->table('companies')->select('companies.symbol')
->leftJoin('trx', 'trx.companies_id', '=', 'companies.id')
->where('trx.transaction_date', '>=', Carbon::today()->subDays(1)->startOfDay())
->orderBy('transaction_date', 'desc')
->distinct()
->get('symbol');
However, I am not sure how to pack the in my eloquent query to get all the symbol back that should be excluded.
I highly appreciate your replies!

You should try something like this:
$date = Carbon::today()->subDays(1)->startOfDay();
DB::connection('mysql_prod')->table('companies')->select('companies.symbol')
->leftJoin('trx', 'trx.companies_id', '=', 'companies.id')
->where('trx.transaction_date', '>=', $date)
->whereNotIn('companies.symbol', function ($q) use ($date) => {
$q->select('companies.symbol')
->from('companies')
->leftJoin('articles', 'articles.companies_id', 'companies.id')
->where('articles.created_at', '>', $date)
->distinct()
->get()
})
->orderBy('transaction_date', 'desc')
->distinct()
->get();
It will provide a similar query as you mentioned.
Reference from here.
Also, you can read how to write sub Query from Laravel docs.
