Laravel 查询生成器连接错误。 SQLSTATE[42000] 错误

Question

我正在使用 Laravel 查询构建器来编写一个连接语句，我发现我遇到了一个奇怪的错误。当我从 phpmyadmin 运行下面的查询时，它可以工作，但是当我尝试访问 Laravel 中的页面时出现错误。

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; 
check the manual that corresponds to your MySQL server version for the right syntax to use near 
'? where `entities`.`deleted_at` is null' at line 1 (SQL: select * from `entities` inner join 
`entity_contact_info` on `entity_contact_info`.`entity_id` = `entities`.`id` and `entities`.`sector_id`
= 2 and `entity_contact_info`.`country_id` IN (select `id` from countries WHERE `region_id` = 9)
where `entities`.`deleted_at` is null)

我在 Laravel 中构建的查询如下。同样，当我从上面的错误中复制查询并运行它时，它可以工作。这似乎没有理由不起作用。

$query = Entity::Join("entity_contact_info", function ($join){
                $join->on("entity_contact_info.entity_id", "=", "entities.id")
                    ->where("entities.sector_id", "=", "2")
                    ->where("entity_contact_info.country_id", "IN", "(select `id` from countries WHERE `region_id` = 9)");
                })->get();

有什么建议吗？

Answer 1

我会说问题在于您的第二个where() 声明。

试试下面的。

->where("entity_contact_info.country_id", "IN", DB::raw("(select `id` from countries WHERE `region_id` = 9)"))

Answer 2

试试这个，

$query = Entity::Join("entity_contact_info", function ($join){
                $join->on("entity_contact_info.entity_id", "=", "entities.id")
                    ->where("entities.sector_id", "=", "2")
                    ->whereIn("entity_contact_info.country_id", DB::raw("(select `id` from countries WHERE `region_id` = 9)"));
                })->get();

另一种方式，

$query = Entity::Join("entity_contact_info", function ($join) {
                $join->on("entity_contact_info.entity_id", "=", "entities.id")
                ->where("entities.sector_id", "=", "2")
            ->whereIn('entity_contact_info.country_id', function($query) {
                $query->select('id')
                    ->from('countries')
                    ->where('countries.region_id = 9');
            })
        })->get();

Use of where IN laravel
