你需要指出你得到的錯誤是什麼。什麼信息？另外，你想要做什麼？您是否試圖簡化SQL以調試更簡單的版本？你是否搜索了錯誤信息？你發現了什麼？ – EdC

什麼是錯誤？ – hims056

我認爲你要使用TblProjectResources.UserId IN瞬間與OR嘗試這樣的：

AND (TblProjectResources.UserId IN 
     (SELECT UserId 
     FROM TblProjectResources 
     WHERE IsRemoved=0 
     AND ProjectApproval=1 
     AND [email protected]) 
    OR 
    TblProjectResources.UserId IN 
     (SELECT TblAssignments.AssigneeId 
     FROM TblTasks,TblAssignments 
     WHERE TblTasks.TaskId=TblAssignments.AssignmentEntityId 
     AND TblAssignments.AssignmentEntity='Task' 
     AND [email protected]) 
    OR 
    TblProjectResources.UserId IN 
     (SELECT UserId FROM TblProjects WHERE [email protected]) 
)

它現在工作非常感謝 –

@ hims056答案應該適合你。就像替代品一樣，您可以嘗試用UNION/UNION ALL替換OR。這也應該起作用。

SELECT TblProjectResources.UserId 
FROM TblTasks,TblProjectResources 
WHERE TblTasks.ProjectId=TblProjectResources.ProjectId 
AND [email protected] AND TblProjectResources.IsRemoved=0 
AND TblProjectResources.UserId IN(
    (SELECT UserId 
     FROM TblProjectResources 
     WHERE IsRemoved=0 
     AND ProjectApproval=1 
     AND [email protected]) 
    UNION 
    (SELECT TblAssignments.AssigneeId 
     FROM TblTasks,TblAssignments 
     WHERE TblTasks.TaskId=TblAssignments.AssignmentEntityId 
     AND TblAssignments.AssignmentEntity='Task' 
     AND [email protected]) 
    UNION 
     (SELECT UserId FROM TblProjects WHERE [email protected]) 
)
