SQL多部分标识符错误

这是我简单的sql代码。当在执行它的抛出和错误。SQL多部分标识符错误

无法绑定多部分标识符“product_hscodes.hscode”。

select DISTINCT mi.*,csq.contract_code 
    from master_items mi 
    join contract_shipment_qty csq on csq.item_code = mi.code 
    join contract c on c.code = csq.contract_code 
    join master_item_products mp on mp.master_item = mi.id 
    join hscode h on h.code = product_hscodes.hscode 
where csq.shipment_id = 6 
    and csq.contract_code = '046V-12-A04-05' 
    and mi.code = 'M165' 
    and h.code = '12345'

我想你忘了加入'product_hscodes'表。 –

不，我试过了。如果我添加到“从”其抛出“mi.code”，也没有发现 – Mifas

，那么你为什么加入这个'h.code = product_hscodes.hscode'加入hscode h？ –

你还没有加入product_hscodes表。

from master_items mi 
join contract_shipment_qty csq on csq.item_code = mi.code 
join contract c on c.code = csq.contract_code 
join master_item_products mp on mp.master_item = mi.id 

join product_hscodes 
    on product_hscodes.fk = <primary table>.pk //<<Have you joined this table? 

join hscode h on h.code = product_hscodes.hscode
