php - 只获取您关注的用户的帖子 mysql 查询

Question

这个问题取决于我之前的问题: MySql get all rows where id = xxx and where the newest column in other table in row with same id is greater than one

我目前正在使用以下查询来获取所有公开用户的所有帖子:

select p.*
    from (select p.*,
                 (select pp.public_type
                  from tbl_post_public pp
                  where pp.post_id = p.post_id
                  order by date desc
                  limit 1
                 ) as latest_public
          from tbl_post p
          order by p.date desc
         ) p
    where latest_public < 80
    limit 10;

但不是，我只想获取我在 Instagram 上关注的用户的帖子我有下表来保存谁正在关注谁:

tbl_user_follow:

id |  user     | follower_user | 
--------------------------------
 0 |  xxxxx4   | xxxxx1 (<-me) |
 1 |  xxxxx8   | xxxxx1 (<-me) |
 2 |  xxxxx3   | xxxxx6        |

所以让我们认为我是用户“xxxxx1”，现在我希望查询查看“xxxxx4”和“xxxxx8”的所有帖子，因为考虑到我之前的问题，我正在关注他们。

非常感谢你，并对我的英语不好感到抱歉:)

您没有指定问题中的表名称或其他表中的字段名称，因此请调整以下内容以匹配这些名称。还将 $user_id 替换为要匹配的 id。

select p1.*
    from (select p.*,
                (select pp.public_type
                from tbl_post_public pp
                where pp.post_id = p.post_id
                order by date desc
                limit 1
                ) as latest_public
        from tbl_post p
        order by p.date desc
        ) p1
    JOIN `tbl_user_follow` f
    ON f.`user` = p1.`user`
    where latest_public < 80
    AND (f.`follower_user` = $userID OR f.`user` = $userID)
    GROUP BY f.`follower_user`, f.`user`
    limit 10;
