MySQL查询显示按数字顺序排序的记录？
使用ORDERBY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 yourTableName order 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)
