Question

这是我的代码......

//Database:: find matching results in feeds table
$users_size = $this->holders($this->followed_users_id);
$slugs_size = $this->holders($this->followed_slugs_id);

$match_query = "select * from feeds " .
    "WHERE (user_id IN ($users_size)) " .
    "OR (target_id IN ($slugs_size) AND feedable_type = 'review') " .
    "ORDER BY created_at DESC;";

    $result = DB::select($match_query, $this->followed_users_id, $this->followed_slugs_id);

并且不要担心（？）占位符，因为它们是根据要求动态生成的，$ this->followed_users_id和$this->followed_slugs_id是数组

结果就是这个

Connection.php第655行中的QueryException： SQLSTATE [HY093]：参数号无效（SQL：select * from feeds WHERE（user_id IN（1,17））OR（target_id IN（？，？）AND feedable_type ='review'）ORDER BY created_at DESC;）

Answer 1

我认为绑定必须在数组中，并作为select方法中的第二个参数

$bindings = array_merge($this->followed_users_id, $this->followed_slugs_id);

$result = DB::select($match_query, $bindings);

如何在闭包中使用原始Laravel查询中的多个占位符（？）
