Question

我正在尝试搜索数据库，查看它们已经打开14天但尚未调用的情况。我检查单词调用的步骤，并可以返回步骤（没有单词调用）。

如果工作调用存在，我想不返回案例（而不是返回单词调用不存在的各个步骤）。

SELECT
    Support_Incident.Support_Incident_Code,
    Support_Incident.Company_Name,
    Support_Incident.Support_Incident_Name,
    Support_Incident.Severity,
    Support_Incident.MF_Status_Display,
    Support_Incident.MF_Action_Owner_Display,
    Support_Step.Description,
    DATEDIFF(hh, Last_Updated, GETDATE()) AS 'Main'
FROM 
    Support_Incident
INNER JOIN Support_Step
    ON Support_Incident.Support_Incident_Id = Support_Step.Support_Incident_Id
    AND (Support_Step.Description NOT LIKE '%phone%'
    AND Support_Step.Description NOT LIKE '%call%')
INNER JOIN Employee
    ON Employee.Employee_Id = Support_Incident.Owner_Id
WHERE 
    (DATEDIFF(hh, Support_Incident.Display_Create_Date, GETDATE()) BETWEEN 336 AND 359
AND Support_Incident.MF_Action_Owner_Display <> 'Update'
AND Support_Incident.MF_Status_Display <> 'Closed'
AND Support_Incident.MF_Status_Display <> 'Defect'
AND Support_Incident.MF_Status_Display <> 'Enhancement'
AND Employee.Rn_Descriptor = '::sName');

Answer 1

你有没有理由

（Support_Step.Description NOT LIKE'％phone％'AND Support_Step.Description NOT LIKE'％call％'）

在join语句中而不在where子句中？

试试这个：

SELECT  
    Inc.Support_Incident_Code,  
    Inc.Company_Name,  
    Inc.Support_Incident_Name,  
    Inc.Severity,  
    Inc.MF_Status_Display,  
    Inc.MF_Action_Owner_Display,  
    Step.[Description],  
    DATEDIFF(hh, Last_Updated, GetDate()) AS 'Main' 
FROM  
    Support_Incident AS Inc 
    INNER JOIN Support_Step AS Step ON Inc.Support_Incident_Id = Step.Support_Incident_Id 
    INNER JOIN Employee AS Emp ON Emp.Employee_Id = Inc.Owner_Id  
WHERE 
    (DATEDIFF(hh, Inc.Display_Create_Date, GetDate()) BETWEEN 336 AND 359  
    AND Inc.MF_Action_Owner_Display <> 'Update'  
    AND Inc.MF_Status_Display <> 'Closed'  
    AND Inc.MF_Status_Display <> 'Defect'  
    AND Inc.MF_Status_Display <> 'Enhancement'               
    AND Emp.Rn_Descriptor = '::sName'  
    AND step.[description] Not Like '%call%');

如果满足条件，如何不返回任何行
