经典ASP - 我可以丢失嵌套循环以换取连接吗？

Question

我正在尝试优化其中一个脚本。这是一个照片网站，使用WHILE WEND循环显示一个大网格图像，循环浏览我的DB（MySQL）照片表。

在这个循环中，我有另一个WHILE END循环，它从我的人员表中获取每张照片中人物的名字。

我的问题是，我可以通过在主查询中添加JOIN来丢失第二个WHILE WEND循环吗？

我的困惑来自于回来不止一个人。我无法弄清楚如何用逗号分隔一个或多个名字，我只是不知道。也许我的脚本很好，但是我确信没有嵌套循环可以更快，因为在某些时候，我正在考虑添加另一个查询，它返回每张照片的前5个关键字，并且不要我想添加另一个循环！

Set rsPhotos = Conn.Execute(" " _
& "SELECT photoID, setID, caption, dateCreated, dateUploaded " _
& "FROM photos ORDER BY dateCreated DESC;)"

While NOT rsPhotos.EOF
    Response.Write "<div>"
        Response.Write "<img src=""photo.jpg"">"
        Response.Write "<p>"
            people_str = ""
            Set rsPeople = Conn.Execute("SELECT p.person FROM photoPeople AS pp " _
            & "LEFT JOIN people AS p USING (personID) " _
            & "WHERE pp.photoID = "&rsPhotos.Fields("photoID")&" " _
            & "ORDER BY p.person ASC;")
            While NOT rsPeople.EOF
                people_str = people_str & ", " & rsPeople.Fields("person")
            rsPeople.MoveNext
            Wend

Answer 1

这应该这样做 -

SELECT photos.photoID, photos.setID, photos.caption, photos.dateCreated, photos.dateUploaded, GROUP_CONCAT(p.person ORDER BY p.person ASC SEPARATOR ', ')
FROM photos
LEFT JOIN photoPeople AS pp
    ON photos.photoID = pp.photoID
LEFT JOIN people AS p
    ON pp.personID = p.personID
GROUP BY photos.photoID
ORDER BY dateCreated DESC

GROUP_CONCAT()
