MySQL 如何从MySQL表获取交替的奇数记录？

为了理解这个概念，我们使用表“ Information ”中的数据如下：

mysql> Select * from Information;
+----+---------+
| id | Name    |
+----+---------+
| 1  | Gaurav  |
| 2  | Ram     |
| 3  | Rahul   |
| 4  | Aarav   |
| 5  | Aryan   |
| 6  | Krishan |
+----+---------+
6 rows in set (0.00 sec)

现在，下面的查询将从上述表“Information”中提取替代的奇数编号记录 –

mysql> Select id,Name from information group by id having mod(id,2) = 1;
+----+-------+
| id | Name  |
+----+-------+
| 1  | Gaurav |
| 3  | Rahul  |
| 5  | Aryan  |
+----+-------+
3 rows in set (0.09 sec)
