如何在laravel中执行此查询？

Question

我想从laravel中的多个表中选择数据。如何在laravel中进行这样的查询？ 这是我想在laravel中使用分页

的查询

$blog = DB::select("select blog_post.*,(select img_name from blog_image WHERE blog_image.bid=blog_post.bid limit 0,1) as img_name, 
    (SELECT count(*) FROM likes WHERE likes.bid =blog_post.bid) AS likes,
    (SELECT count(*) FROM comment WHERE comment.bid =blog_post.bid ) as comments ,
    (SELECT count(*) FROM blog_share WHERE blog_share.bid =blog_post.bid ) as  share 
    from blog_post WHERE status=1 AND is_draft=0 AND is_publish=1 AND is_delete=0")->paginate(2);

这是一个非常标准的查询。首先，您需要为每个表创建一个模型，并在BlogPost模型中创建define relationships。

要计算关系，请使用withCount()方法。
