我有一个经典的 ASP 页面，其中有我的所有客户（大约 4,000 个），无论是否处于活动状态，我需要在 4 个不同的表中获取有关它们的信息。我目前的做法是，我的页面需要 3、4、5 分钟，具体取决于服务器的繁忙程度。有时我什至会在 asp 中收到一条消息，上面写着“超出了脚本执行的最长时间”。我的查询如下，
1. 我得到了我的客户的个人信息
2. 我得到了我的客户的销售额
3. 在有了这些信息之后，我对我的客户数组进行了一个 for 循环以获取其他信息。在那个循环中，我做了 5 个不同的查询。

我获得的所有信息在我的页面中都是必需的。
做这一切的最好方法是什么？

（我正在研究视图、触发器、功能/程序）

查询（法语）：1。

我将您的所有查询合二为一。我做了一些假设，比如每个客户只需要一条记录。需要添加的变量在花括号中。 

SELECT NoClient, Gamme, Vente, Annee, Mois, Dateouverture, NomClient, CodeClient,
    NoClientFront, NoVendeur, VilleClient, DateOuverture, Telemarketing, Autre1,
    MAX(DatePlanification) AS DatePlanification, MAX(DateVisite ) AS DateVisite, Email
FROM Client
    JOIN AchatClient USING (NoClient)
    JOIN planification USING (NoClient)
    JOIN visite_kterm USING (NoClient)
    JOIN DateFacture USING (NoClient)
    LEFT JOIN SDS ON (NoClient = NoCompte)
WHERE (CodeClient LIKE 'C%' OR CodeClient LIKE 'N%')
    AND Annee BETWEEN {AnneeRanking} AND {AnneeRanking - 1}
    AND DatePlanification <= {todayDate}
    AND Etat=0
    AND Email like '%@%' AND Email like '%.%'
GROUP BY NoClient
ORDER BY NoClient

该查询将受益于如下所列的索引：

SDS - single index on `NoCompte`
planification - make the `NoClient` index composite like (`NoClient`, `DatePlanification`)
achatclient - single index on `Annee`

此外，将所有NoClient列设为其中一种INT类型。

使用这样的单个查询应该比大量的串行查询快得多。您可能需要根据数据将一些JOINs 切换为LEFT JOINs。
