How to order by auto_increment in MySQL?
Let us first create a table −
mysql> create table DemoTable(Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,FirstName varchar(100));
Query OK, 0 rows affected (0.70 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(FirstName) values('Chris');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable(FirstName) values('Robert');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable(FirstName) values('David');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable(FirstName) values('Mike');
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable(FirstName) values('Adam');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable(FirstName) values('Carol');
Query OK, 1 row affected (0.12 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----+-----------+
| Id | FirstName |
+----+-----------+
| 1 | Chris |
| 2 | Robert |
| 3 | David |
| 4 | Mike |
| 5 | Adam |
| 6 Carol |
+----+-----------+
6 rows in set (0.00 sec)
Following is the query to order by auto_increment −
mysql> select *from DemoTable order by Id DESC;
This will produce the following output −
+----+-----------+
| Id | FirstName |
+----+-----------+
| 6 | Carol |
| 5 | Adam |
| 4 | Mike |
| 3 | David |
| 2 | Robert |
| 1 | Chris |
+----+-----------+
6 rows in set (0.00 sec)
