Question

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。

Answer 1

试试这个!!

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 > DATEADD(HOUR, -1, GETDATE())

Answer 2

尝试以下查询：

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);

Answer 3

类似于TeamDataViz的答案。 IMO更具可读性。

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)

如果您只希望在过去的一天之前关注记录，WHERE子句将变得更加简单

WHERE receivedate > GETDATE() - 12

获取上一小时的记录
