Question

我们被要求创建一个SQL语句来显示Rattlesnake Canyon Grocery在1997-01-01中所下订单的总订单金额。但是，ORDERS表与CUSTOMERS表不同。

所以这就是我所做的：

SELECT Orders.OrderID, 
    Orders.CustomerID, 
    Orders.EmployeeID, 
    Orders.OrderDate, 
    Orders.ShipperID, 
    Customers.CustomerID, 
    Customers.CustomerName, 
    Customers.ContactName, 
    Customers.Address, 
    Customers.City, 
    Customers.PostalCode, 
    Customers.Country
FROM Customers
INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID;
WHERE DATE = 1997-01-01

但是它向我展示了一个'错误'标志。如何解决这个问题？错误说：“无法准备”。

Answer 1

您忘记在date添加引号并添加分号的错误位置。

 SELECT Orders.OrderID, 
        Orders.CustomerID, 
        Orders.EmployeeID, 
        Orders.OrderDate, 
        Orders.ShipperID, 
        Customers.CustomerID, 
        Customers.CustomerName, 
        Customers.ContactName, 
        Customers.Address, 
        Customers.City, 
        Customers.PostalCode, 
        Customers.Country
    FROM Customers
    INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID //u added semicolon here which is wrong
    WHERE DATE = '1997-01-01';

Answer 2

您没有任何DATE列，请将 DATE列替换为 Orders.OrderDate 以及半列在错误的地方

SELECT Orders.OrderID, 
    Orders.CustomerID, 
    Orders.EmployeeID, 
    Orders.OrderDate, 
    Orders.ShipperID, 
    Customers.CustomerID, 
    Customers.CustomerName, 
    Customers.ContactName, 
    Customers.Address, 
    Customers.City, 
    Customers.PostalCode, 
    Customers.Country
FROM Customers 
INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID
WHERE Orders.OrderDate= '1997-01-01';
