二、日期查询

2.1 MySql

统计今年每一个月数据

select res.day,ifnull(warn.count+warn.pcount,0) as count,ifnull(warn.pcount,0)as pcount,ifnull(warn.fcount,0)as fcount,ifnull(warn.handled,0)as handledfrom (SELECT concat(year(curdate()),'-12') as dayunion allSELECT concat(year(curdate()),'-11') as dayunion allSELECT concat(year(curdate()),'-10') as dayunion allSELECT concat(year(curdate()),'-09') as dayunion allSELECT concat(year(curdate()),'-08') as dayunion allSELECT concat(year(curdate()),'-07') as dayunion allSELECT concat(year(curdate()),'-06') as dayunion allSELECT concat(year(curdate()),'-05') as dayunion allSELECT concat(year(curdate()),'-04') as dayunion allSELECT concat(year(curdate()),'-03') as dayunion allSELECT concat(year(curdate()),'-02') as dayunion allSELECT concat(year(curdate()),'-01') as day) resleft join (select DATE_FORMAT(create_time, '%Y-%m') as datetime, count(event_level=1 or null) as pcount,count(event_level=2 or null) as count, count(event_level=3 or null) as fcount,count(event_state='1' or null) as handledfrom t_run_equ_eventwhere  dept_id='101'   and YEAR(create_time)=YEAR(NOW())group by datetime) warn on res.day = warn.datetimeorder by res.day asc

其中create_time格式为：yyyy-mm-dd hh:mm:ss。

1.2 最近7天

 select res.day,ifnull(warn.count+warn.pcount,0) as count,ifnull(warn.pcount,0)as pcount,ifnull(warn.fcount,0)as fcount,ifnull(warn.handled,0)as handledfrom (SELECT curdate() as dayunion allSELECT date_sub(curdate(), interval 1 day) as dayunion allSELECT date_sub(curdate(), interval 2 day) as dayunion allSELECT date_sub(curdate(), interval 3 day) as dayunion allSELECT date_sub(curdate(), interval 4 day) as dayunion allSELECT date_sub(curdate(), interval 5 day) as dayunion allSELECT date_sub(curdate(), interval 6 day) as day) resleft join (select date(event_time) as datetime, count(event_level=1 or null) as pcount,count(event_level=2 or null) as count,count(event_level=3 or null) as fcount, count(event_state='1' or null) as handledfrom t_run_equ_eventwhere  dept_id='101'   and DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= DATE(event_time)group by date(event_time)) warn on res.day = warn.datetimeorder by res.day asc

1.3 最近30天告警数和整改数+去年同期数

1.4 今年告警数和整改数+去年同期数

select curYear.warns,curYear.handled,lYear.lwarns,lYear.lhandledfrom(select ifnull(warn.warns,0)warns,ifnull(handle.handled,0)handled from (select count(*) warns,dept_idfrom t_run_equ_event ewhere e.dept_id=#{deptId} and e.event_level='2' and   YEAR(create_time)=YEAR(NOW()))warnLEFT JOIN(SELECT count(*)handled,dept_id from t_run_work_orderwhere dept_id=#{deptId}  and work_state='1' and  YEAR(create_time)=YEAR(NOW()))handle on warn.dept_id=handle.dept_id) curYearLEFT JOIN (select ifnull(warn.warns,0)lwarns,ifnull(handle.handled,0)lhandled from (select count(*) warns,dept_idfrom t_run_equ_event ewhere e.dept_id=#{deptId} and  YEAR(create_time)=YEAR(date_sub(now(),interval 1 year)))warnLEFT JOIN(SELECT count(*)handled,dept_id from t_run_work_orderwhere dept_id=#{deptId}  and work_state='1' and  YEAR(create_time)=YEAR(date_sub(now(),interval 1 year)))handle on warn.dept_id=handle.dept_id)lYear on 1=1

2.2 SqlServer

2.1 本月每一天

   select res.day as cal_date, isnull(warn.total_num,0)total_num, isnull(warn.fire_alarm_num, 0)fire_alarm_num,isnull(warn.error_num,0)error_num, isnull(warn.leave_post_count,0)leave_post_count, isnull(warn.other_num,0)other_numfrom (

2.2 最近一年每个月统计

 select res.month as sta_month, isnull(warn.total_num,0)total_num, isnull(warn.fire_alarm_num, 0)fire_alarm_num,isnull(warn.error_num,0)error_num, isnull(warn.leave_post_count,0)leave_post_count, isnull(warn.other_num,0)other_numfrom (SELECT 1 as monthunion all SELECT 2  as monthunion all SELECT 3  as monthunion all  SELECT 4  as monthunion all  SELECT 5  as monthunion all SELECT 6  as monthunion all SELECT 7  as monthunion all SELECT 8  as monthunion all SELECT 9  as monthunion all SELECT 10  as monthunion all SELECT 11  as monthunion all SELECT 12  as month) resleft join (select sta_month,sum(total_num) total_num,sum(t.fire_alarm_num) fire_alarm_num, sum(t.error_num) error_num,sum(t.leave_post_count) leave_post_count,sum(t.total_num-t.fire_alarm_num-t.error_num-t.leave_post_count) other_num from T_RMCF_MONTH_STATISTICS t inner join T_RMCF_SYS_DWXX dw on dw.dwid=t.dwid and dw.del_flag='0' where t.sta_year='2022' group by sta_month) warn on res.month = warn.sta_monthorder by res.month asc

2.3 最近7天数据统计

 select res.day as cal_date, warn.total_num, warn.fire_alarm_num, warn.error_num, warn.leave_post_count, warn.other_numfrom (SELECT convert(varchar(10), getdate(), 112) as dayunion allSELECT convert(varchar(10), dateadd(dd,-1,getdate()), 112)  as dayunion allSELECT convert(varchar(10), dateadd(dd,-2,getdate()), 112)  as dayunion allSELECT convert(varchar(10), dateadd(dd,-3,getdate()), 112)  as dayunion allSELECT convert(varchar(10), dateadd(dd,-4,getdate()), 112)  as dayunion allSELECT convert(varchar(10), dateadd(dd,-5,getdate()), 112)  as dayunion allSELECT convert(varchar(10), dateadd(dd,-6,getdate()), 112)  as day) resleft join (select cal_date, sum(total_num) total_num,sum(t.fire_alarm_num) fire_alarm_num, sum(t.error_num) error_num,sum(t.leave_post_count) leave_post_count, sum(t.total_num-t.fire_alarm_num-t.error_num-t.leave_post_count) other_numfrom T_RMCF_DAY_STATISTICS t inner join T_RMCF_SYS_DWXX dw on dw.dwid=t.dwid and dw.del_flag='0' where t.cal_date>='2022-05-06'  group by cal_date) warn on res.day = warn.cal_dateorder by res.day asc

三、两者区别

方法类型，实现稍有区别，主要上数据库自带日期函数不同。
