从2015-01-01开始到2015-01-31,提取每天22点到第二天9点的数据，注意有开始时间（START_TIME）和结束时间（END_TIME）
我的sql：
select A.BILLING,sum(out + in) from inf.EVEN_TGAS A
where A.START_TIME between '2015-01-01 22:00:00' and '2015-01-31 09:00:00'
and A.end_TIME between '2015-01-01 22:00:00' and '2015-01-31 09:00:00'
GROUP BY A.BILLING
limit 10;
怎么才能不提取比如像2015-01-02 14:23:50那个时间点的数据呢？？？
麻烦各位大神了
你试下这样是否满足你的要求，按照你所写的内容，因为有开始时间和结束时间，所以会有很多数据时间上是处于交叉的，
如开始时间满足时间要求，但是结束时间不在咱们的时间段内，这些我都给算成是不统计的数据了。
微信扫一扫 select A.BILLING,sum(out + in) from inf.EVEN_TGAS A
where (SUBSTRING(A.START_TIME,1,11) >= '2015-01-01' and SUBSTRING(A.START_TIME,1,11)<= '2015-01-31')--判断开始日期是否符合时间段
and (SUBSTRING(A.end_TIME,1,11) >= '2015-01-01' and SUBSTRING(A.end_TIME,1,11)<= '2015-01-31')--判断结束日期是否符合时间段
and (
(SUBSTRING(A.START_TIME,12,8) >= '22:00:00' and SUBSTRING(A.START_TIME,12,8)<= '23:59:59')
or
(SUBSTRING(A.START_TIME,12,8) >= '00:00:00' and SUBSTRING(A.START_TIME,12,8)<= '09:00:00')
)and (
(SUBSTRING(A.end_TIME,12,8) >= '22:00:00' and SUBSTRING(A.end_TIME,12,8)<= '23:59:59')
or
(SUBSTRING(A.end_TIME,12,8) >= '00:00:00' and SUBSTRING(A.end_TIME,12,8)<= '09:00:00')
)and (
datediff(second,A.START_TIME,A.end_TIME) <= 39600 -- 保证时间不是跨度好多天的数据
)
GROUP BY A.BILLING
limit 10;
语句比较繁杂，你可以试着优化优化
那就别用between 了，用 > 和 <
ERROR: column "second" does not exist 这个怎么解决啊
