mysql查询获取两个给定日期之间的结果

Question

我正在尝试从MySQL服务器获取数据，该数据目前在两个给定的日期之间，我正在执行这些查询以获取所需的结果，并取得了很多成果：

SELECT mdn,recharge_status_code, recharge_status_code_desc, date_time
FROM impressions_log 
WHERE recharge_status_code in ('515') 
AND date(date_time) IN ('2014-05-18','2014-05-19','2014-05-20','2014-05-21','2014-05-22') 

我还能够找到一个查询解决方案，但是它既没有给出任何错误，也没有任何结果：

SELECT mdn,recharge_status_code, recharge_status_code_desc, date_time, retry_status
FROM impressions_log 
WHERE recharge_status_code IN ('515') AND date(date_time) = DATEDIFF('2014-05-18','2014-05-24')

Answer 1

尝试这个：

SELECT 
    mdn,
    recharge_status_code,
    recharge_status_code_desc,
    date_time,
    retry_status 
FROM impressions_log 
WHERE recharge_status_code in ('515') 
    AND DATE(date_time) BETWEEN '2014-05-18' AND '2014-05-24';

Answer 2

假设您的日期是连续的，则可以将查询更改为使用BETWEEN或相应地使用>和< 。

SELECT mdn,recharge_status_code, recharge_status_code_desc, date_time
FROM impressions_log 
WHERE recharge_status_code in ('515') 
    AND date(date_time) BETWEEN '2014-05-18' AND '2014-05-22'

要么：

SELECT mdn,recharge_status_code, recharge_status_code_desc, date_time
FROM impressions_log 
WHERE recharge_status_code in ('515') 
    AND date_time >= '2014-05-18' AND date_time < '2014-05-23'

我更喜欢后面的版本，因为您不必进行任何转换。
