MySQL的选择statment

Question

我有以下MySQL表

OrderId OrderItemId IsReceived 
    1   21   0 
    1   22   1 
    2   31   1 
    2   11   0 
    2   21   0 
    3   31   1 
    3   12   1 

• 如果IsReceived == 1，表示这个项目被接收。

• 如果IsReceived == 0，表示此项目尚未收到。

我想知道哪些订单已被完全接收（所有orderItems接收），什么是MySQL查询？

在这种情况下，它会返回一个OrderId：3（因为在orderId 3，收到的所有订单项）

Answer 1

这里有一个解决方案：

SELECT OrderId 
FROM `IHaveFollowingMySQLTable` 
GROUP BY OrderID 
HAVING MIN(IsReceived) = 1 

Answer 2

而另一

SELECT OrderId 
    FROM OrderItems 
GROUP BY OrderID 
HAVING SUM(IsReceived) = COUNT(IsReceived) 

但@Bill Karwin的答案是最优雅的。

Answer 3

select distinct(tbl.OrderId) from your_table_name tbl where tbl.OrderId not in 
(select distinct(tbl2.OrderId) from your_table_name tbl2 where tbl2.IsReceived=0)
