Select the topmost record from a table ordered by desc on the basis of ID?
For this, use ORDER BY DESC with LIMIT 1. Let us first create table −
mysql> create table DemoTable
-> (
-> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
-> UserName varchar(100),
-> UserMessage text
-> );
Query OK, 0 rows affected (1.17 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(UserName,UserMessage) values('Adam','Hi');
Query OK, 1 row affected (0.92 sec)
mysql> insert into DemoTable(UserName,UserMessage) values('Chris','Awesome');
Query OK, 1 row affected (0.52 sec)
mysql> insert into DemoTable(UserName,UserMessage) values('Robert','Nice');
Query OK, 1 row affected (0.65 sec)
mysql> insert into DemoTable(UserName,UserMessage) values('David','Good Morning!!!');
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 | UserName | UserMessage |
+----+----------+-----------------+
| 1 | Adam | Hi |
| 2 | Chris | Awesome |
| 3 | Robert | Nice |
| 4 | David | Good Morning!!! |
+----+----------+-----------------+
4 rows in set (0.00 sec)
Following is the query to select the topmost record from a table −
mysql> select *from DemoTable order by Id DESC limit 1;
This will produce the following output −
+----+----------+-----------------+
| Id | UserName | UserMessage |
+----+----------+-----------------+
| 4 | David | Good Morning!!! |
+----+----------+-----------------+
1 row in set (0.00 sec)
