Get all rows apart from first and last in MySQL

To get all rows apart from first and last, use subquery along with MIN() and MAX(). Let us first create a table −

mysql> create table DemoTable1917
   (
   StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentCode int,
   StudentMarks int
   );
Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,95);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,96);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,97);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,98);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1917(StudentCode,StudentMarks) values(78,99);
Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1917;

This will produce the following output −

+-----------+-------------+--------------+
| 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)

Here is the query to get all rows apart from first and last:

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;

This will produce the following output −

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