Answer 1

SELECT O.OrderID 
     ,E.EmployeeID 
     ,O.OrderDate 
FROM dbo.Orders O INNER JOIN dbo.Employees E 
ON O.EmployeeID = E.EmployeeID 
WHERE YEAR(O.OrderDate) = 1996 
AND MONTH(O.OrderDate)= 7 
AND E.FirstName IN ('Nancy','Janet', 'Steven') 

嚴格使用AND和OR操作

SELECT O.OrderID 
     ,E.EmployeeID 
     ,O.OrderDate 
FROM dbo.Orders O INNER JOIN dbo.Employees E 
ON O.EmployeeID = E.EmployeeID 
WHERE YEAR(O.OrderDate) = 1996 
AND MONTH(O.OrderDate)= 7 
AND 
    ( E.FirstName = 'Nancy' 
     OR E.FirstName = 'Janet' 
     OR E.FirstName = 'Steven' 
    )
