mysql - 具有 DATE mysql 函数的 Laravel 查询生成器

Question

您好，我在我的 laravel 项目中有一个查询，它应该检索范围之间的日期。我的查询是:

 $dateFrom = date("Y-m-d", strtotime($request->dateFrom));
      $dateTo = date("Y-m-d", strtotime($request->dateTo));
      $posts = DB::table('posts')->join('categories','posts.category_id','=','categories.id')->
                join('users','posts.user_id','=','users.id')
                ->select('posts.id','posts.topic','categories.category_name','posts.created_at','users.name')
                ->whereBetween('posts.created_at',[$dateFrom,$dateTo])
                ->get();

我想在 posts.created_at 列上使用 DATE mysql_function，但我不知道该怎么做。以下查询不起作用:

$dateFrom = date("Y-m-d", strtotime($request->dateFrom));
      $dateTo = date("Y-m-d", strtotime($request->dateTo));
       $posts = DB::table('posts')->join('categories','posts.category_id','=','categories.id')->
                join('users','posts.user_id','=','users.id')
                ->select('posts.id','posts.topic','categories.category_name','posts.created_at','users.name')
                ->whereBetween('DATE(posts.created_at)',[$dateFrom,$dateTo])
                ->get();

我很乐意提供帮助。最好的问候 ;)

Answer 1

更改 ->whereBetween('DATE(posts.created_at)'

到 ->whereBetween(DB::raw('DATE(posts.created_at)'))

如果您想在查询中添加一些原始表达式，您可以使用 DB::row 方法，如 laravel documentation 中所述
