Question

当我尝试使用此代码在我的表salesfacts中插入数据时，它表示0行会受到影响，但是当我删除插入时，只执行select，它会显示我的salesfacts表。任何人都可以帮我解决这个问题。

truncate table SalesFacts

INSERT INTO Assignment1SS..SalesFacts
(ProductCode, CustomerNumber, EmployeeNumber, officeCode, buyPrice, MSRP, quantityOrdered) 

SELECT 

p.ProductCode, 
c.CustomerNumber, 
e.EmployeeNumber, 
y.officeCode, 
p.buyPrice, 
p.MSRP, 
od.quantityOrdered

FROM
Assignemnt1..[OrderDetails] od INNER JOIN Assignemnt1..[Orders] o
ON od.orderNumber = o.orderNumber

INNER JOIN Assignment1SS..[ProductSS] p 
ON od.productCode = p.productCode

INNER JOIN Assignment1SS..[CustomersSS] c
ON od.OrderNumber = c.CustomerNumber

INNER JOIN Assignment1SS..[EmployeeSS] e
ON c.SalesRepEmployeeNumber = e.EmployeeNumber

INNER JOIN

(select e.[EmployeeNumber], y.[officeCode]
from Assignemnt1..[Employees] e
inner join Assignemnt1..[Offices] y
on e.officeCode = y.officeCode
group by e.[EmployeeNumber],y.[officeCode]) y

on c.salesRepEmployeeNumber = y.EmployeeNumber

CustomersSS表

    Create Table CustomersSS (
CustomerNumber int NOT NULL,
CustomerName varchar (50) NOT NULL,
ContactLastName varchar (50) NOT NULL,
ContactFirstName varchar (50) NOT NULL,
Phone varchar (50) NOT NULL,
AddressLine1 varchar (50) NOT NULL,
