Laravel Eloquent with two “WHERE NOT IN” in subquery - mysql

Question

I have this query that I am having trouble to write query in laravel eloquent ORM.
Appreciate if someone can help.
Here is SQL Expression:
SELECT DISTINCT cust, cust_no FROM delivery_sap
WHERE cust NOT IN ( SELECT cust_name FROM customer)
AND cust_no NOT IN ( SELECT cust_code FROM customer)

Answer 1

Instead of executing 3 different queries you can use like shown below,
DB::table('delivery_sap')
->whereNotIn('cust', function ($query) {
$query->select('cust_name')->from('customer');
})
->whereNotIn('cust_no', function ($query) {
$query->select('cust_code')->from('customer');
})
->select('cust', 'cust_no')
->distinct('cust')
->get();
This code will give the exact same query which is asked in the question,
to check the query, use following code
DB::table('delivery_sap')
->whereNotIn('cust', function ($query) {
$query->select('cust_name')->from('customer');
})
->whereNotIn('cust_no', function ($query) {
$query->select('cust_code')->from('customer');
})
->select('cust', 'cust_no')
->distinct('cust')
->toSql();
Output will be,
select distinct `cust`, `cust_no` from `delivery_sap`
where `cust` not in (select `cust_name` from `customer`)
and `cust_no` not in (select `cust_code` from `customer`)

Answer 2

Try Something like this:
DB::table('delivery_sap')
->whereNotIn('cust', DB::table('customer')->pluck('cust'))
->whereNotIn('cust_no', DB::table('customer')->pluck('cust_no'))
->select('cust', 'cust_no')
->groupBy('cust', 'cust_no')
->get();

Answer 3

I corrected the code below pluck('cust') to pluck('cust_name') and
pluck('cust_no') to pluck('cust_code') and it works
DB::table('delivery_sap')
->whereNotIn('cust', DB::table('customer')->pluck('cust_name'))
->whereNotIn('cust_no', DB::table('customer')->pluck('cust_code'))
->select('cust', 'cust_no')
->groupBy('cust', 'cust_no')
->get();

You could use exists or left join for better performance instead of sub queries on same table like in existing solution, there is no need for these 2 extra sub queries
SELECT DISTINCT cust, cust_no
FROM delivery_sap d
WHERE EXISTS (
SELECT 1
FROM delivery_sap
WHERE cust_name = d.cust OR cust_code = d.cust
)
OR
SELECT DISTINCT d.cust, d.cust_no
FROM delivery_sap d
LEFT JOIN delivery_sap d1 ON d.cust = d1.cust_name OR d.cust = d1.cust_code
WHERE d1.cust IS NULL
DB::table('delivery_sap as d')
->leftJoin('delivery_sap as d1', function ($join) {
$join->on('d.cust','=','d1.cust_name')
->orWhere('d.cust', '=', 'd1.cust_code');
})
->whereNull('d1.cust')
->select('cust', 'cust_no')
->distinct()
->get();
