让我们首先创建一个表，其中一列为ID-

mysql> create table DemoTable
   (
   ID int,
   StudentName varchar(10),
   CountryName varchar(20)
   );

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable values(0,'David','AUS');
mysql> insert into DemoTable values(3,'Chris','UK');
mysql> insert into DemoTable values(8,'Carol','US');
mysql> insert into DemoTable values(9,'Sam','US');
mysql> insert into DemoTable values(12,'Robert','UK');
mysql> insert into DemoTable values(10,'Mike','AUS');

使用select语句显示表中的所有记录-

mysql> select *from DemoTable;

输出结果

+------+-------------+-------------+
| ID   | StudentName | CountryName |
+------+-------------+-------------+
| 0    | David       | AUS         |
| 3    | Chris       | UK          |
| 8    | Carol       | US          |
| 9    | Sam         | US          |
| 12   | Robert      | UK          |
| 10   | Mike        | AUS         |
+------+-------------+-------------+
6 rows in set (0.00 sec)

以下是查找ID可被4整除的所有行的查询-

mysql> select *from DemoTable where (ID%4)=0;

输出结果

+------+-------------+-------------+
| ID   | StudentName | CountryName |
+------+-------------+-------------+
| 0    | David       | AUS         |
| 8    | Carol       | US          |
| 12   | Robert      | UK          |
+------+-------------+-------------+
3 rows in set (0.30 sec)
