使用内部联接更新mysqli查询

Question

如何执行查询并设置完成值= 1如果0反之亦然，我尝试了这段代码但是没有工作：

UPDATE orders set orders.done=1 inner 
JOIN mydate on orders.order_no=mydate.order_no and orders.date=mydate.order_date 
where done.orders=0

Answer 1

试试这个：

UPDATE orders 
join mydate on orders.order_no=mydate.order_no and orders.date=mydate.order_date 
set orders.done=1
where order.orders=0
