-- time_str '2016-11-20 04:31:11'
-- date_str 20161120

select concat(left(date_format(time_str, '%y-%m-%d %h:%i'),15),'0') as time_flag, count(*) as count from `security`.`cmd_info` where `date_str`=20161120 
group by time_flag order by time_flag; -- 127 rows

select round(unix_timestamp(time_str)/(10 * 60)) as timekey, count(*) from `security`.`cmd_info` where `date_str`=20161120 group by timekey 
order by timekey; -- 126 rows

-- 以上2個SQL語句的思路類似——使用「group by」進行區分，但是方法有所不同，前者只能針對10分鐘(或1小時)級別，后者可以動態調整間隔大小，兩者效率差不多，
可以根據實際情況選用

select concat(date(time_str),' ',hour(time_str),':',round(minute(time_str)/10,0)*10), count(*) from `security`.`cmd_info` where `date_str`=20161120 
group by date(time_str), hour(time_str), round(minute(time_str)/10,0)*10; -- 145 rows

select concat(date(time_str),' ',hour(time_str),':',floor(minute(time_str)/10)*10), count(*) from `security`.`cmd_info` where `date_str`=20161120 
group by date(time_str), hour(time_str), floor(minute(time_str)/10)*10; -- 127 rows (和 date_format 那個等價)

select concat(date(time_str),' ',hour(time_str),':',ceil(minute(time_str)/10)*10), count(*) from `security`.`cmd_info` where `date_str`=20161120 
group by date(time_str), hour(time_str), ceil(minute(time_str)/10)*10; -- 151 rows
