在MySQL中获取除第一行和最后一行之外的所有行

要使所有行与第一行和最后一行分开，请与MIN()和一起使用子查询MAX()。让我们首先创建一个表-

mysql> create table DemoTable1917
   (
   StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentCode int,
   StudentMarks int
   );

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,95);
mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,96);
mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,97);
mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,98);
mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,99);

使用select语句显示表中的所有记录-

mysql> select * from DemoTable1917;

这将产生以下输出-

+-----------+-------------+--------------+
| StudentId | StudentCode | StudentMarks |
+-----------+-------------+--------------+
|         1 |          78 |           95 |
|         2 |          78 |           96 |
|         3 |          78 |           97 |
|         4 |          78 |           98 |
|         5 |          78 |           99 |
+-----------+-------------+--------------+
5 rows in set (0.00 sec)

这是获取除第一行和最后一行之外的所有行的查询：

mysql> select * from DemoTable1917
   where StudentId NOT IN
   (
   (
   select min(StudentId) from DemoTable1917 where StudentCode=78),
   (select max(StudentId) from DemoTable1917 where StudentCode=78)
   ) and StudentCode=78;

这将产生以下输出-

+-----------+-------------+--------------+
| StudentId | StudentCode | StudentMarks |
+-----------+-------------+--------------+
|         2 |          78 |           96 |
|         3 |          78 |           97 |
|         4 |          78 |           98 |
+-----------+-------------+--------------+
3 rows in set (0.00 sec)
