Laravel Eloquent在子查询中带有两个“ WHERE NOT IN”

Question

我有这个查询，我很难在Laravel雄辩的ORM中编写查询。

感谢有人可以提供帮助。

这是SQL表达式：

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

无需执行3个不同的查询，您可以使用如下所示的方法，

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();

该代码将给出与问题完全相同的查询，以检查查询，使用以下代码

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();

输出将是

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

尝试这样的事情：

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

我将下面的代码更正为 pluck('cust') 为 pluck('cust_name') 和 pluck('cust_no') 为 pluck('cust_code') 并且它有效

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();
