Question

所以我正在尝试为作业创建一个商务系统。我使用QSEE创建了ERD here is a screen shot of it。我尝试将每个单独的语句复制并粘贴到SQL功能中，但它会抛出有关不存在的字段的错误消息，导入整个文档不起作用：

ALTER TABLE _customerorder ADD CONSTRAINT fk1__customerorder_to__payment FOREIGN KEY(fk1_PaymentID) REFERENCES _payment(PaymentID) ON DELETE RESTRICT ON UPDATE RESTRICT;

ALTER TABLE _orderedproduct ADD CONSTRAINT fk1__orderedproduct_to__customerorder FOREIGN KEY(fk1_OrderID,fk1_fk1_CustomerID) REFERENCES _customerorder(OrderID,fk1_CustomerID) ON DELETE RESTRICT ON UPDATE RESTRICT;

ALTER TABLE _orderedproduct ADD CONSTRAINT fk2__orderedproduct_to__product FOREIGN KEY(fk2_ProductID) REFERENCES _product(ProductID) ON DELETE RESTRICT ON UPDATE RESTRICT;

ALTER TABLE _product ADD CONSTRAINT fk1__product_to__supplier FOREIGN KEY(fk1_SupplierID) REFERENCES _supplier(SupplierID) ON DELETE RESTRICT ON UPDATE RESTRICT;

ALTER TABLE _customerorder ADD CONSTRAINT fk2__customerorder_to__customer FOREIGN KEY(fk2_CustomerID) REFERENCES _customer(CustomerID) ON DELETE RESTRICT ON UPDATE RESTRICT

PHPmyAdmin抛出错误，无法成功导入sql;
