mysql没有提供unix时间戳的专门处理函数,所以,如果遇到时间分组,而你用的又是整型unix时间戳,则只有转化为mysql的其他日期类型! FROM_UNIXTIM()将unix时间戳转为datetime等日期型! 特殊情况:createtime为int时,写法如下 select * from paycord where month(FROM_UNIXTIME(createtime, '%y-%m-%d')) = month(curdate()) and year(FROM_UNIXTIME
统计常用的sql 统计常用的sql语句: 今天的所有数据:select * from 表名 where DateDiff(dd,datetime类型字段,getdate())=0 昨天的所有数据:select * from 表名 where DateDiff(dd,datetime类型字段,getdate())=1 7天内的所有数据:select * from 表名 where DateDiff(dd,datetime类型字段,getdate())<=7 30天内的所有数据:select *
现有数据如上图所示,要求统计出日期相同的Count总数,并且加一列统计前面日期Count的总和 1 SELECT SUM([Count]) AS DayTotal, SUM(SUM([Count])) over (order by [Datetime]) Total, [datetime] FROM Table_3 2 GROUP BY [DateTime] 3 ORDER BY [DateTime] DESC 结果如下: Total列是日期小于当前行的DayTotal列的总和:比如第三行 日期
-- 统计三月的每天的数据量 select count(*),substr(t.date,1,10) from table t where t.date like '2010-03%' group by substr(t.date,1,10) ; --统计从5月19到6月29的数据量 SELECT substr(a.feed_publish_time,1, 10) AS '日期', count(*) AS '医说数' FROM xm_feed a WHERE a.feed_publish_tim
sql代码如下: 统计重复的数据 select MingCheng from tabShouFeiGongShi group by MingCheng having count(MingCheng) >= 2 select * from (select *from tabShouFeiGongShiwhere MingCheng in (select MingCheng from tabShouFeiGongShi group by MingCheng having count(MingChe
