如何在同一天内获取数据？

Question

我正在进行查询以在同一天内计算已验证的订单。关于如何计算，我可以做但是为了限制时间，你能帮助我吗？

例如：TIMESTAMPDIFF(HOUR, enddate, startdate) <= '24'，时间将在1天内，但可以是从一天到第二天。那么如何在同一天内获取数据呢？我的原始查询是：

SELECT COUNT(*),
1.0 * count(CASE WHEN TIMESTAMPDIFF(HOUR, `Created Datetime`, `Order Verification Date`) <= '2' THEN `BOB Sales Order Item` ELSE NULL END) / COUNT(`BOB Sales Order Item`) AS within_2hours_rate,
1.0 * count(CASE WHEN TIMESTAMPDIFF(DAY, `Created Datetime`, `Order Verification Date`) <= '24' THEN `BOB Sales Order Item` ELSE NULL END) / COUNT(`BOB Sales Order Item`) AS within_the_sameday_rate
FROM data.oms
WHERE `Created Datetime` BETWEEN '2017-10-29 00:00:00' AND '2017-11-04 23:59:59' AND `Order Verification Status` = 'finance_verified'

提前致谢！

如果你想检查两次是在同一个日历日那么你可以做DATE(`Created Datetime`) = DATE(`Order Verification Date`)。
