具有多个条件的 Laravel Eloquent 内连接

问题描述

我有一个关于具有多个值的内部连接的问题.我确实在 Laravel 中构建了这样的代码.

I have a question about inner joins with multiple on values. I did build my code like this in laravel.

public function scopeShops($query) {
    return $query->join('kg_shops', function($join)
    {
        $join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
        // $join->on('kg_shops.active', '=', "1"); // WRONG
        // EDITED ON 28-04-2014
        $join->on('kg_shops.active', '=', DB::raw("1"));

    });
}

唯一的问题是，它给出了这个结果:

Only problem is, it gives this outcome:

Column not found: 1054 Unknown column '1' in 'on clause' (SQL: select `kg_feeds`.* from `kg_feeds` inner join `kg_shops` on `kg_shops`.`id` = `kg_  
  feeds`.`shop_id` and `kg_shops`.`active` = `1`) (Bindings: array (                                                                                        )) 

如您所见，join 中的多个条件没有问题，但它认为 1 是一列而不是字符串.这是否可能，或者我必须在何处修复它.

As you can see, the multiple conditions in the join go fine, but it thinks the 1 is a column instead of a string. Is this even possible, or do I have to fix it in the where.

提前致谢！

推荐答案

return $query->join('kg_shops', function($join)
 {
   $join->on('kg_shops.id', '=', 'kg_feeds.shop_id');

 })
 ->select('required column names') 
 ->where('kg_shops.active', 1)
 ->get();
