如何从不同 tables SQL 的日期范围输出 table 字段的结果

Question

我有 table 个带有 table 个标题

员工

staffID   staffName   staffAge

产品

productID   productDescription   productCost

订单

orderID   customerID   orderDate   orderLocation

orderServedby

orderID   staffID   servedBy

订单汇总

orderID   customerID   productID   summaryOfOrder

我想根据日期（orderDate)

到目前为止我有这个...

SELECT 
    staff.staffID,
    order.orderLocation, orderSummary.productID
FROM 
    staff
INNER JOIN 
    orderServedby ON staff.staffID = orderServedby.staffID
INNER JOIN 
    ordersummary ON product.ProductID = orderSummary.productID
WHERE 
    OrderDate BETWEEN #07/04/1996# AND #07/09/1996#;

我不确定如何将它们 link 在一起，因为它们都依赖 orderID 来获得正确的列？抱歉，我是 SQL 的新手。谢谢

Answer 1

这应该让你开始：

SELECT 
    staff.staffID,
    order.orderLocation, 
    orderSummary.productID
 from Order
    inner join orderServedBy on orderServedBy.OrderId = Order.OrderId
    inner join orderSummary on orderSummary.OrderId = Order.OrderId
where OrderDate BETWEEN #07/04/1996# AND #07/09/1996#
  and ServedBy = '<some value here>'
