Only display row with highest ID in MySQL
To order, use the ORDER BY DESC clause. With that, since we want a single ID, which should be the highest, use LIMIT 1. This will fetch the row with highest ID. Let us first create a table −
mysql> create table DemoTable ( Id int, FirstName varchar(50) ); Query OK, 0 rows affected (0.83 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(100,'Chris'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable values(110,'Robert'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable values(120,'Mike'); Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable values(115,'Bob'); Query OK, 1 row affected (0.14 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+------+-----------+ | Id | FirstName | +------+-----------+ | 100 | Chris | | 110 | Robert | | 120 | Mike | | 115 | Bob | +------+-----------+ 4 rows in set (0.00 sec)
Following is the query to display row with highest ID −
mysql> select *from DemoTable order by Id DESC LIMIT 1;
This will produce the following output −
+------+-----------+ | Id | FirstName | +------+-----------+ | 120 | Mike | +------+-----------+ 1 row in set (0.00 sec)
