【问题描述】：

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 = ???????

我在任何地方都在使用 Sybase 自适应服务器并尝试获取最近一小时的记录。

类似于 TeamDataViz 的回答。只是更具可读性 IMO。

SELECT Field1, OrderFor, Writeback, Actshipdate, Orderstatus, receivedate, receivetime
FROM orderinfo, shippinginfo
WHERE orderinfo.orderid = shippinginfo.orderid
AND shippinginfo.custid = '37782'
WHERE receivedate BETWEEN DATEADD(HOUR,-1,GETDATE()) AND CAST(GETDATE() AS DATE)

如果您只想关注过去一天的记录，那么 WHERE 子句会变得更加容易

WHERE receivedate > GETDATE() - 12

试试下面的查询：

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 >= (sysdate-1/24);

    WHERE orderinfo.orderid = shippinginfo.orderid
    AND shippinginfo.custid = '37782'
