MySQL查询，查找订单为0/无订单的客户

我想找到那些还没有下订单的客户

我找到了一些查询，以查找按客户分类的订单总数，但无法找到/获取任何查询，该查询将返回未进入订单表的客户ID

还想排序的结果按日期，如在上个月，去年等

如有任何帮助/想法，将不胜感激

谢谢

怎么样

SELECT c.*
FROM Customers c LEFT JOIN
Orders o ON c.CustomerID = o.CustomerID
WHERE o.CustomerID IS NULL

它有助于上传表的结构，你没有查询的样本…绝对不存在的方式去。

SELECT c.*
FROM Customers c
WHERE NOT EXISTS (SELECT 1 FROM Orders o WHERE o.CustomerID = c.CustomerID)

select c.* from Customers c
where c.CustomerID NOT IN (select o.CustomerID from Orders o)

select customer_name from customer               
where customer_id not in (select customer_id from orders);
