我创建了 2 个临时表#ClientsCountForDoctor和#DeathCount：

CREATE TABLE #ClientsCountForDoctor (DoctorCode int, Clients int)   

SELECT 
   Personal.[DoctorCode], Count(Clients.[ClientCode]) AS [Count-Код клиента]
FROM 
   Personal 
INNER JOIN 
   (Clients INNER JOIN MedicalCard ON Clients.[ClientCode] = MedicalCard.[ClientCode]) ON Personal.[DoctorCode] = MedicalCard.[DoctorCode]
GROUP BY 
   Personal.[DoctorCode];

INSERT INTO #ClientsCountForDoctor
EXEC nothing

CREATE TABLE #DeathCount (DoctorCode int, Deaths int)   

SELECT 
    Personal.[DoctorCode], Count(Clients.[ClientCode]) AS [Count-Код клиента]
FROM 
    Personal 
INNER JOIN 
    (Clients INNER JOIN MedicalCard ON Clients.[ClientCode] = MedicalCard.[ClientCode]) ON Personal.[DoctorCode] = MedicalCard.[DoctorCode]
GROUP BY 
    Personal.[DoctorCode], MedicalCard.[TreatmentResult]
HAVING 
    (((MedicalCard.[TreatmentResult])='Смерть'));

INSERT INTO #DeathCount
EXEC nothing

然后我想使用结果。我应该执行什么？

SELECT 
   Personal.[DoctorName], 
   #DeathCount.Deaths/#ClientsCountForDoctor.Clients AS [DeathPercent]
FROM 
   (#ClientsCountForDoctor INNER JOIN Personal ON #ClientsCountForDoctor.[DoctorCode] = Personal.[DoctorCode]) 
INNER JOIN 
   #DeathCount ON Personal.[DoctorCode] = #DeathCount.[DoctorCode];

我认为你需要的是Select Into语法。It will create the table for you with the selected data inserted at the same time. 然后从最后一个查询中使用创建的表进行正常选择

前任：

SELECT col1,col2,..
INTO #temp          --Note: this temporary table will be created in the db
FROM yourTable

您的疑问：

SELECT Personal.[DoctorCode], 
       Count(Clients.[ClientCode]) AS [Count-Код клиента]
INTO #ClientsCountForDoctor --NOTE

FROM Personal INNER JOIN 
 (Clients INNER JOIN MedicalCard ON Clients.[ClientCode] = MedicalCard.[ClientCode]) 
           ON  Personal.[DoctorCode] = MedicalCard.[DoctorCode]
GROUP BY Personal.[DoctorCode];


SELECT Personal.[DoctorCode], 
       Count(Clients.[ClientCode]) AS [Count-Код клиента]
#DeathCount  --NOTE

FROM Personal INNER JOIN 
  (Clients INNER JOIN MedicalCard ON Clients.[ClientCode] = MedicalCard.[ClientCode]) 
          ON Personal.[DoctorCode] = MedicalCard.[DoctorCode]
GROUP BY Personal.[DoctorCode], MedicalCard.[TreatmentResult]
HAVING (((MedicalCard.[TreatmentResult])='Смерть'));


SELECT p.[DoctorName], d.Deaths/c.Clients AS [DeathPercent]
FROM #ClientsCountForDoctor c INNER JOIN Personal p
     ON c.[DoctorCode] = p.[DoctorCode]
           INNER JOIN #DeathCount d 
     ON p.[DoctorCode] = d.[DoctorCode];
