between 的范圍是包含兩邊的邊界值

eg： id between 3 and 7 等價(jià)與 id >=3 and id<=7

not between 的范圍是不包含邊界值

eg：id not between 3 and 7 等價(jià)與 id < 3 or id>7

SELECT * FROM `test` where id BETWEEN 3 and 7;等價(jià)于 SELECT * FROM `test` where id>=3 and id<=7;-----------------------------------------------------------SELECT * FROM `test` where id NOT BETWEEN 3 and 7;等價(jià)于 SELECT * FROM `test` where id<3 or id>7;mysql between日期邊界的問(wèn)題留意邊界問(wèn)題：

mysql， between 開(kāi)始日期 AND 結(jié)束日期 包含開(kāi)始日期，不包含結(jié)束日期

BETWEEN ’2018-01-22’ AND ’2018-01-30’

開(kāi)始日期從2018-01-22 00:00:00.0 開(kāi)始， 到2018-01-29 23:59:59.59結(jié)束

表中的CREATE_DATE 是varchar(21) DEFAULT NULL COMMENT ’時(shí)間’,

CREATE_DATE中保存值是： 年-月-日 時(shí)：分：秒：0 例如： 2018-01-29 23:45:35.0

SELECT * FROM Test a WHERE a.CREATE_DATE BETWEEN ’2018-01-22’ AND ’2018-01-30’ ORDER BY a.CREATE_DATE desc

SELECT * FROM TABEL a WHERE a.CREATE_DATE BETWEEN ’2018-01-22’ AND ’2018-01-30’ ORDER BY a.CREATE_DATE desc 2018-01-29 23:45:35.0 20180129 2018-01-29 23:45:33.0 20180129 2018-01-29 00:10:58.0 20180129 2018-01-29 00:10:45.0 20180129 2018-01-28 23:42:23.0 20180128 2018-01-28 23:39:39.0 20180128SELECT * FROM TABEL a WHERE a.CREATE_DATE BETWEEN ’2018-01-22’ AND ’2018-01-29’ ORDER BY a.CREATE_DATE desc 2018-01-28 23:42:23.0 20180128 2018-01-28 23:39:39.0 20180128 2018-01-28 00:13:22.0 20180128 2018-01-28 00:13:19.0 20180128 2018-01-27 23:23:02.0 20180127 2018-01-22 00:09:59.0 20180122 2018-01-22 00:09:56.0 20180122 2018-01-22 00:01:53.0 20180122

遇到的其他問(wèn)題：

遇到另外一張表 test2 有保存時(shí)間的字段： `REPORTTIME` varchar(45) DEFAULT NULL,

這個(gè)字段保存的值是：

select * from bips_hpd_helpdesk a WHERE str_to_date(from_unixtime(a.REPORTTIME,’%Y-%m-%d’),’%Y-%m-%d’) BETWEEN ’2018-01-16’ AND ’2018-01-27’ ORDER BY from_unixtime(a.REPORTTIME,’%Y-%m-%d’) DESC ;

結(jié)果1：

從結(jié)果中，可以看到取到了27號(hào)的數(shù)據(jù)，可能是處理的時(shí)間沒(méi)有 小時(shí)，分鐘，秒。

select * from bips_hpd_helpdesk a WHERE str_to_date(from_unixtime(a.REPORTTIME,’%Y-%m-%d’),’%Y-%m-%d’) BETWEEN str_to_date(’2018-01-16’,’%Y-%m-%d’) AND str_to_date(’2018-01-27’,’%Y-%m-%d’)

結(jié)果2：

找到問(wèn)題： 毫秒值轉(zhuǎn)換為時(shí)間，發(fā)現(xiàn)這里保存的毫秒值，沒(méi)有保存時(shí)分秒：

from_unixtime(a.REPORTTIME,’%Y-%m-%d’) AS reportTime,a.REPORTTIME, str_to_date(from_unixtime(a.REPORTTIME,’%Y-%m-%d’),’%Y-%m-%d %h:%i:%s’) AS reportTime22FROM test a WHERE str_to_date(from_unixtime(a.REPORTTIME,’%Y-%m-%d’),’%Y-%m-%d %h:%i:%s’) BETWEEN str_to_date(’2018-01-16’,’%Y-%m-%d %h:%i:%s’) AND str_to_date(’2018-01-27 %h:%i:%s’,’%Y-%m-%d’) #subdate(curdate(),date_format(curdate(),’%w’)-1) AND subdate(curdate(),date_format(curdate(),’%w’)-8)ORDER BY from_unixtime(a.REPORTTIME,’%Y-%m-%d’) DESC ;

查看到的時(shí)間值：

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
