mysql - SQL 更新查询错误

Question

这以前有效，但现在不起作用，我很困惑。我回顾了整个事情，一切看起来都很好，但也许更高级的人可以发现一些东西？

这是脚本：

UPDATE Orders SET Orders.OrderStatus = 'Shipped',Orders.SalesRep_CustomerID = null
WHERE Orders.OrderStatus in ('Pending','Processing') 
AND Orders.PaymentAmount = Orders.Total_Payment_Received
AND Orders.ShipDate < dateadd(day, -60, convert(char(10), getdate(), 101))
AND Orders.Shipped = Y

我得到的只是一个错误，没有解释。有人能发现错误吗，我敢肯定，我对 SQL 太陌生了，无法识别它。谢谢

Answer 1

不确定您遇到的错误是什么，但您需要在引号中加上 Y。

UPDATE Orders SET Orders.OrderStatus = 'Shipped',Orders.SalesRep_CustomerID = null
WHERE Orders.OrderStatus in ('Pending','Processing') 
AND Orders.PaymentAmount = Orders.Total_Payment_Received
AND Orders.ShipDate < dateadd(day, -60, convert(char(10), getdate(), 101))
AND Orders.Shipped = 'Y'

Answer 2

最后一行的 Y 必须在 ''

UPDATE Orders SET Orders.OrderStatus = 'Shipped',Orders.SalesRep_CustomerID = null
WHERE Orders.OrderStatus in ('Pending','Processing') 
AND Orders.PaymentAmount = Orders.Total_Payment_Received
AND Orders.ShipDate < dateadd(day, -60, convert(char(10), getdate(), 101))
AND Orders.Shipped = 'Y'

或者如果您也发布错误会很好

Answer 3

UPDATE Orders SET Orders.OrderStatus = 'Shipped',Orders.SalesRep_CustomerID = null WHERE Orders.OrderStatus in ('Pending','Processing') AND Orders.PaymentAmount = Orders.Total_Payment_Received AND Orders.ShipDate < dateadd(day, -60,转换（char（10），getdate（），101））和 Orders.Shipped = 'Y'
