MySQL的未知列

Question

我有這個疑問：

select orders.* 
     ,customers.name as customername 
     ,customers.city as customercity 
     ,managers.name as managername 
     ,godowns.name as godownname 
from orders 
inner join customers 
inner join managers 
inner join godowns on orders.customerid=customers.customerid 
        and orders.managerid=managers.managerid 
        and orders.godownid=godowns.godownid 
order by orderid desc; 

我收到以下錯誤：

未知列 '的條款' 在 'orders.customerid'

我一直在竊聽這一整天。它在一個系統中運行，而不在另一個系統中運行

Answer 1

select orders.*,customers.name as customername,customers.city as customercity,managers.name as managername,godowns.name as godownname 
from orders 
inner join customers on orders.customerid=customers.customerid 
inner join managers on orders.managerid=managers.managerid 
inner join godowns on orders.godownid=godowns.godownid 
order by orderid desc 

每個連接需要一個on條款
