echarts圖表統計----時間

最近想用Echart做數據統計的圖形顯示，數據來源是MySQL數據庫，自然需要根據不同的搜索條件篩選出表中的數據，用比較多的就是時間的參數吧！

常用的mysql時間的條件進行檢索的SQL語句：

數據表名:tableName 字段名:myDate 

最近7天的,
SELECT * FROM tableName where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(myDate);

最近一個月的
SELECT * FROM tableName where DATE_SUB(CURDATE(), INTERVAL 1 MONTH) <= date(myDate);

最近1年的
SELECT * FROM tableName where DATE_SUB(CURDATE(), INTERVAL 1 YEAR) <= date(myDate);

本周的 (是從周日開始)
SELECT * FROM tableName where YEARWEEK(DATE_FORMAT(myDate,'%Y-%m-%d')) = YEARWEEK(now());

上周的
SELECT * FROM tableName where YEARWEEK(DATE_FORMAT(myDate,'%Y-%m-%d')) = YEARWEEK(now())-1;

本月的
SELECT * FROM tableName where date_format(myDate,'%Y-%m')=date_format(now(),'%Y-%m')

上個月的
SELECT * FROM tableName where date_format(myDate,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m');

距離現在6個月的數據
SELECT * FROM tableName where myDate between date_sub(now(),interval 6 month) and now();

今年的數據，按月分組
SELECT month(fly_timeStart) as month,count(*) FROM flightinfo.tab_flight_info where year(fly_timeStart)=2019 group by month(fly_timeStart);

獲取當月第一天
select DATE_ADD(CURDATE(),INTERVAL-DAY(CURDATE())+1 day);

獲取上月最后一天
select DATE_SUB(CURDATE(),INTERVAL DAY(CURDATE())+0 day);
我想做的是統計最近一年，不包括當月的數據，按月統計；以及當月的數據，按天統計。

開始的語句是這樣的，但是這是按當前日期往前推，我想要從當月第一天往前推，即不包括當月的數據。

最近1年的數據，按月分組
SELECT plane_type, year(fly_timeStart) as year,month(fly_timeStart) as month,count(*) as count 
FROM tab_flight_info where DATE_SUB(curdate(), INTERVAL 1 YEAR) <= date(fly_timeStart) AND plane_type='機型1' 
group by year(fly_timeStart),month(fly_timeStart);
於是改成如下語句，curdate() 改成 DATE_SUB(CURDATE(),INTERVAL DAY(CURDATE())+0 day：

最近1年的數據，按月分組
SELECT plane_type, year(fly_timeStart) as year,month(fly_timeStart) as month,count(*) as count FROM tab_flight_info where
 DATE_SUB(DATE_SUB(CURDATE(),INTERVAL DAY(CURDATE())+0 day), INTERVAL 1 YEAR) <= date(fly_timeStart) AND plane_type='機型1' 
group by year(fly_timeStart),month(fly_timeStart);
然后是按月統計：

最近一個月的數據，按天分組
SELECT month(fly_timeStart),day(fly_timeStart),count(*) FROM flightinfo.tab_flight_info where DATE_SUB(CURDATE(), INTERVAL 1 MONTH) <= date(fly_timeStart) 
group by month(fly_timeStart),day(fly_timeStart);

獲取當月數據
SELECT * from tab_flight_info where DATE_FORMAT(fly_timeStart,'%Y%m')=DATE_FORMAT(CURDATE(),'%Y%m');
獲取當月數據
SELECT month(fly_timeStart) as month,day(fly_timeStart) as day,count(*) as count from tab_flight_info 
where DATE_FORMAT(fly_timeStart,'%Y%m')=DATE_FORMAT(CURDATE(),'%Y%m') AND plane_type='機型1' group by day(fly_timeStart);
