参数问题

Question

感谢您的支持，了解以下代码的错误：

SELECT [Name] As Milestone, [Start], [Outgoing tasks] As OTask 
FROM [Sheet1$] 
WHERE [Main project] = 'Company A' AND [Main link] = 'Project 1' 
AND [Task class] = 'Company' 
AND [Start] > (SELECT [Start] 
               FROM [Sheet1$] 
               WHERE [Main project] = 'Company A' 
               AND [Main link] = 'Project 1' 
               AND [Name] = OTask 
               AND [Incoming tasks] = Milestone)

我实际上要做的是获取在其后继（Name）之后发生的注册表（Outgoing tasks）。

我的参数（Milestone和OTask）是否存在问题？

ERROR: NO VALUE GIVEN FOR ONE OR MORE REQUIRED PARAMETERS

感谢!!!

问题是你在where where条件下使用你的别名。

它应该是这样的

SELECT [Name] As Milestone, [Start], [Outgoing tasks] As OTask 
FROM [Sheet1$] 
WHERE [Main project] = 'Company A' AND [Main link] = 'Project 1' 
AND [Task class] = 'Company' 
AND [Start] > (SELECT [Start] 
               FROM [Sheet1$] 
               WHERE [Main project] = 'Company A' 
               AND [Main link] = 'Project 1' 
               AND [Name] = [Outgoing tasks]
               AND [Incoming tasks] = [Name])

您必须将OTask替换为[Outgoing tasks]而将Milestone替换为[Name]
