 4 CREATE TABLE emp
 5 (
 6     empno INT PRIMARY KEY,
 7     ename VARCHAR(10),
 8     sal INT

15 INSERT INTO emp VALUES (5,'martin',1600);
16 INSERT INTO emp VALUES (6,'blake',3000);

2.BETWEEN…AND…

Comparing whether the data in a specified interval within the closed range

. 1  - Query sal data between 1500 and 3000 (including 1500 and 3000) 
2  the SELECT  *  the FROM EMP the WHERE sal > =  1500  the AND sal <=  3000 ;
 . 3  - equivalent 
. 4  the SELECT  *  the FROM EMP the WHERE sal the BETWEEN  1500  the AND  3000 ;

3.NOT BETWEEN…AND…

A comparison whether the data is not within the range specified closed interval

. 1  - Query sal less than 1500 or more than 3000 data (not including 1500 and 3000) 
2  the SELECT  *  the FROM EMP the WHERE sal <  1500  OR sal >  3000 ;
 . 3  - equivalent 
. 4  the SELECT  *  the FROM EMP the WHERE sal the NOT  the BETWEEN  1500  the AND  3000 ;
