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)
