Select the next row after skipping every 2 rows in MySQL
To skip rows, you can use OFFSET. Let us first create a table −
mysql> create table DemoTable617(Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,FirstName varchar(100)); Query OK, 0 rows affected (1.70 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable617(FirstName) values('John');
Query OK, 1 row affected (0.39 sec)
mysql> insert into DemoTable617(FirstName) values('Sam');
Query OK, 1 row affected (0.39 sec)
mysql> insert into DemoTable617(FirstName) values('Carol');
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable617(FirstName) values('Mike');
Query OK, 1 row affected (0.34 sec)
mysql> insert into DemoTable617(FirstName) values('David');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable617(FirstName) values('Bob');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable617(FirstName) values('Robert');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable617(FirstName) values('Chris');
Query OK, 1 row affected (0.27 sec)
mysql> insert into DemoTable617(FirstName) values('Mike');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable617(FirstName) values('Adam');
Query OK, 1 row affected (0.49 sec)Display all records from the table using select statement −
mysql> select *from DemoTable617;
This will produce the following output −
+----+-----------+ | Id | FirstName | +----+-----------+ | 1 | John | | 2 | Sam | | 3 | Carol | | 4 | Mike | | 5 | David | | 6 | Bob | | 7 | Robert | | 8 | Chris | | 9 | Mike | | 10| Adam | +----+-----------+ 10 rows in set (0.00 sec)
Following is the query to select rows. At first order by DESC. After that, it will skip two rows and display 5 rows using LIMIT 5 −
mysql> select tbl.* from (select *from DemoTable617 order by FirstName DESC LIMIT 5 OFFSET 2) AS tbl ORDER BY tbl.Id ;
This will produce the following output −
+----+-----------+ | Id | FirstName | +----+-----------+ | 1 | John | | 4 | Mike | | 5 | David | | 8 | Chris | | 9 | Mike | +----+-----------+ 5 rows in set (0.00 sec)
