MySQL中 delete from 時提示 1064 錯誤。

select * from wms_inventory i WHERE not EXISTS (select 1 from wms_item t where t.id=i.SKU_ITEM_ID and t.company_id=i.COMPANY_ID);

select *  from wms_inventory i LEFT JOIN wms_item t on t.id=i.SKU_ITEM_ID and t.company_id=i.COMPANY_ID where t.id is null;

 

delete from wms_inventory i WHERE not EXISTS (select 1 from wms_item t where t.id=i.SKU_ITEM_ID and t.company_id=i.COMPANY_ID);

delete from wms_inventory i LEFT JOIN wms_item t on t.id=i.SKU_ITEM_ID and t.company_id=i.COMPANY_ID where t.id is null;

改為

delete i.* from wms_inventory i WHERE not EXISTS (select 1 from wms_item t where t.id=i.SKU_ITEM_ID and t.company_id=i.COMPANY_ID);

delete i.* from wms_inventory i LEFT JOIN wms_item t on t.id=i.SKU_ITEM_ID and t.company_id=i.COMPANY_ID where t.id is null;

 

原因：因為insert、update、delete都只能針對一個表操作！
