php - 如何对内部联接进行联接？

Question

我有这个数据库:

表格

id  fname       dphone      count_pic   dup_id  

6055903 Karla       5126xxx798  1       57  
6173767 Aaliyah     4082xxx534  4       39  
5611411 Aaliyah     4082xxx534  15      39  
5611211 Aaliyah     4082xxx534  18      39  
4234798 Abby        3057xxx974  31      16  
6166691 Walter      6178xxx280  1       74  
3375576 Walter      6178xxx280  17      74

我发现了如何像这样对其进行内部连接:

SELECT *
  FROM table t1
INNER JOIN (SELECT MIN(count_pic) AS minpic,
               MAX(count_pic) AS maxpic,
               dup_id
          FROM table
      GROUP BY dup_id) t2 ON t1.dup_id = t2.dup_id
                         AND (t1.count_pic = minpic
                           OR t1.count_pic = maxpic)

但是，如果我想根据 id 将此表与另一个表连接起来，并从第二个表中返回一些值，例如 date，，该怎么办:

表2

    id  date

6055903 111111111
6173767 111111111
5611411 111111111

对此有什么想法吗？

编辑:

内部连接就这样很好，我需要在该查询之上添加 table2

Answer 1

只需在末尾添加另一个JOIN:

SELECT *
  FROM table t1
INNER JOIN (SELECT MIN(count_pic) AS minpic,
               MAX(count_pic) AS maxpic,
               dup_id
          FROM table
      GROUP BY dup_id) t2 ON t1.dup_id = t2.dup_id
                         AND (t1.count_pic = minpic
                           OR t1.count_pic = maxpic)

INNER JOIN table2 ON t1.id = table2.id -- add this
