Php mysql查询-仅从另一个表中选择其中id=id，并且该表中的字段=值

我的标题可能无法解释我要找的是什么，这是我目前对某商店推出产品的查询：

mysql_query("SELECT * FROM Items 
             WHERE ((Items.menu_id='$menu_id' AND Items.status='1') 
                   $colour_sql) 
             $order_sql 
             LIMIT $lim_from,$limit_per_page");

上面写着$COLOR\u sql的那部分我想说：

AND (Items.id=colour.product_id AND colour.colour='pink')

所以它只显示粉红色的产品，颜色在单独的表格中。我一直在寻找答案，但我似乎找不到一个能解释我的情况的答案，可能是因为我不知道自己在寻找什么，谢谢你的帮助。

也许是内心的加入

[...]
FROM Items
INNER JOIN colour
ON colour.id = Items.colour_id
WHERE [blablabla]
AND colour.colour = 'pink'

也许是内部连接

[...]
FROM Items
INNER JOIN colour
ON colour.id = Items.colour_id
WHERE [blablabla]
AND colour.colour = 'pink'

如果要使用table

color

进行连接，则需要执行连接或子选择

加入

$menu_id = mysql_real_escape_string($menu_id);
mysql_query = "SELECT i.* 
  FROM items i
  INNER JOIN colour c ON (c.product_id = i.id)
  WHERE i.menu_id = '$menu_id' 
    AND i.status = '1'
    AND c.colour = 'pink'
  ORDER BY .....
  LIMIT {intval($limit_per_page)} OFFSET {intval($lim_from)} ";

$menu_id = mysql_real_escape_string($menu_id);
mysql_query = "SELECT i.* 
  FROM items i
  WHERE i.menu_id = '$menu_id' 
    AND i.status = '1'
    AND i.id IN (SELECT c.product_id FROM colour c WHERE c.colour = 'pink')
  ORDER BY .....
  LIMIT {intval($limit_per_page)} OFFSET {intval($lim_from)} ";

您需要将颜色表添加到查询中：

FROM Items,colour

或

---

但我注意到您的颜色表中有产品标识。为什么不在添加颜色id的项目表中执行相反的操作。

产品可以有多种颜色，所以我不能这样做，如果我理解正确，这只是一个观察：）产品可以有多种颜色，所以我不能这样做，如果我理解正确，这只是一个观察：）
