SQL 服务器查询速度慢 - 怎么优化呢？
SQL Server query slow - how do optimize it?
我需要一些帮助来优化此查询以使其更快。
此查询生成一个视图，后者将显示在网站的 table 中。
这个查询很慢，我正在努力让它更快。
到目前为止，我唯一尝试过的就是减少为 table.
检索的列数
这是查询：

这是一个非常片面的回答，但您问过如何在多个子查询中引用一次 table 而不是多次。
这是一个示例，说明如何将所有这些子查询替换为 Patients & Treatments table 以及城市 table。您真的需要了解联接。
FROM dbo.Clients AS C
join dbo.Cities on Cities.ID=c.CityID
left join (
SELECT ClientId,
COUNT(*) AS TotalPatientCount,
sum(case when IsDeleted = 0 AND IsDisabled = 0 then 1 else 0 end) AS ActivePatientCount,
MAX(CreatedWhen) AS LastPatientAddition
FROM dbo.Patients
GROUP BY ClientId
) Patients on Patients.ClientId = C.Id
left join (
SELECT ClientId,
COUNT(*) AS TotalTreatmentCount,
MAX(CreatedWhen) AS LastTreatmentAddition
FROM dbo.Treatments
GROUP BY ClientId
) Treatments on Treatments.ClientID = C.Id
然后您的列列表将子查询替换为 Patients 和 City，如下所示：
Cities.Name AS City,
Patients.TotalPatientCount,
Patients.ActivePatientCount,
Patients.LastPatientAddition,
Treatments.TotalTreatmentCount,
Treatments.LastTreatmentAddition,
这至少应该给你一个想法。
我将添加第二个答案，这是完整的 sql。这当然没有经过测试，因为我们无法访问您的数据，但我认为您应该能够自己调试它。这段代码中有很多指示应该告诉你如何去。
最基本的是取出所有相关查询并将它们作为子查询。这样做的唯一原因是您使用的所有 Max/Min - 根据您的数据，我会认为它们不是必需的，然后您应该将它们取出并直接加入表格。所有子查询都是左连接 - 如果可以，请根据您的数据再次将它们设为正常连接。
也把外面的组按Id去掉了，99%肯定没这个必要，Top 100%位也是。
