You're Query is just wrong. 'Except' doesn't exist in MS ACCESS. You can easily avoid the usage of Except with the following structure:
你的查询是错误的。MS ACCESS 中不存在“除外”。您可以通过以下结构轻松避免使用Except：
Select *
from tableA
where NOT EXISTS
...
Or
或者
Select *
from tableA
where NOT IN
...
In your Case (if M_Ids is the same type as Member_ID):
在您的案例中（如果 M_Ids 与 Member_ID 的类型相同）：
Select [Member_Id] From Member_Details md
WHERE NOT EXISTS
(select [M_Ids] from Books_Issue WHERE [M_Ids] = md.[Member_ID])
