sql – 获取上一小时的记录

我有这个问题：

SELECT Field1,OrderFor,Writeback,Actshipdate,Orderstatus,receivedate,receivetime
FROM orderinfo,shippinginfo
WHERE orderinfo.orderid = shippinginfo.orderid
AND shippinginfo.custid = '37782'
AND receivedate =  DATE(NOW())
AND receivetime = ???????

我在任何地方使用Sybase自适应服务器并尝试获取最后一小时的记录.

解决方法

SELECT Field1,receivetime
    FROM orderinfo,shippinginfo
    WHERE orderinfo.orderid = shippinginfo.orderid
    AND shippinginfo.custid = '37782'
    AND receivedate =  DATE(NOW())
     AND receivetime > DATEADD(HOUR,-1,GETDATE())
