MySQL এর সাথে একটি পরিসরে নির্দিষ্ট সারি নির্বাচন করবেন?

আসুন প্রথমে একটি টেবিল তৈরি করি -

mysql> create table DemoTable
   (
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentName varchar(20)
   );
Query OK, 0 rows affected (1.23 sec)

সন্নিবেশ কমান্ড −

mysql> insert into DemoTable(StudentName) values('John');
Query OK, 1 row affected (0.08 sec)
mysql> insert into DemoTable(StudentName) values('Carol');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable(StudentName) values('David');
Query OK, 1 row affected (0.07 sec)
mysql> insert into DemoTable(StudentName) values('Bob');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(StudentName) values('Chris');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(StudentName) values('Robert');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable(StudentName) values('Adam');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable(StudentName) values('Mike');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable(StudentName) values('Sam');
Query OK, 1 row affected (0.16 sec)

সিলেক্ট স্টেটমেন্ট -

mysql> select *from DemoTable;

| 9  | Sam         |
+----+-------------+
9 rows in set (0.00 sec)

এখানে নির্দিষ্ট সারি MySQL −

mysql> select *from DemoTable ORDER BY Id DESC LIMIT 4 OFFSET 2;

আউটপুট
