MySQL查询显示按数字顺序排序的记录?
使用ORDER BY并设置差异以显示按数字差异排序的记录。以下是语法-
select *from yourTableNameorder by (yourIntegerColumnName1 - yourIntegerColumnName2);
让我们首先创建一个表-
mysql> create table DemoTable1313-> (
-> Name varchar(20),
-> Score1 int,
-> Score2 int
-> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1313 values('Chris',40,60);mysql> insert into DemoTable1313 values('David',70,50);
mysql> insert into DemoTable1313 values('Adam',35,30);
使用select语句显示表中的所有记录-
mysql> select *from DemoTable1313;
输出结果
+-------+--------+--------+| Name | Score1 | Score2 |
+-------+--------+--------+
| Chris | 40 | 60 |
| David | 70 | 50 |
| Adam | 35 | 30 |
+-------+--------+--------+
3 rows in set (0.00 sec)
以下是按数字差异排序的查询-
mysql> select *from DemoTable1313-> order by (Score1-Score2);
输出结果
+-------+--------+--------+| Name | Score1 | Score2 |
+-------+--------+--------+
| Chris | 40 | 60 |
| Adam | 35 | 30 |
| David | 70 | 50 |
+-------+--------+--------+
3 rows in set (0.00 sec)
