oracle中的between使用

oracle between

測試環境：

Oracle Database 10g Enterprise Edition/SQL*Plus 10.2.0.4.

遇到一個要使用between的小case，專門又看了下，結果發現了小宇宙

先建個表吧：

create table test_s
(
id number,
col2 date,
col3 varchar(10)
);

本人渣渣，怎麼簡單怎麼來哦

這裏只談了下 number類型和date類型

插點數據

insert into test_s values(1,'20160920 23:00:00','2015-03-01');
insert into test_s values(2,'20160920 23:00:01','2015-03-02');
insert into test_s values(3,'20160920 23:00:02','2015-03-04');
insert into test_s values(4,'20160920 22:00:00','2015-03-04');
insert into test_s values(5,'20160920 22:02:00','2015-03-05');
insert into test_s values(11,'20160921 23:00:00','2015-04-02');
insert into test_s values(12,'20160921 23:00:01','2015-04-04');
insert into test_s values(13,'20160921 23:00:02','2015-04-05');
insert into test_s values(15,'20160921 22:02:00','2015-04-06');
insert into test_s values(14,'20160921 22:00:00','2015-04-07');

select * from  test_s;

看看between的效果

select * from test_s where id between 2 and 12 order by 1;

1）.也就是說，number類型左右區間都是閉區間。

select * from 
test_s where col2 between '20160920 23:00:00' and '20160921 23:00:00' order by 2;

select * from 
test_s where col2 between '20160920 23:00:00' and '20160921 23:00:01' order by 2;

看來是我眼花了，這個也是全閉區間。

select * from test_s where col3 between '2015-03-01' and '2015-04-02' order by 3;

。。。。。。。。。。。

搞了半天，between 就是左右全閉區間
