Get MAX and MIN values along with their row id in MySQL?

You can use aggregate function MAX() and MIN() for this.

Let us first create a table −

mysql> create table DemoTable    (    Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,    Number1 int,    Number2 int    ); Query OK, 0 rows affected (0.89 sec)

Insert records in the table using insert command −

mysql> insert into DemoTable(Number1,Number2) values(67,45); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable(Number1,Number2) values(90,40); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable(Number1,Number2) values(80,43); Query OK, 1 row affected (0.48 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable ;

This will produce the following output −

+----+---------+---------+ | Id | Number1 | Number2 | +----+---------+---------+ | 1 | 67 | 45 | | 2 | 90 | 40 | | 3 | 80 | 43 | +----+---------+---------+ 3 rows in set (0.00 sec)

Following is the query to get MAX and MIN values along with their row id −

mysql> select * from DemoTable where Number1 = (select max(Number1) from DemoTable) or Number2 = (select min(Number2) from DemoTable);

This will produce the following output −

+----+---------+---------+ | Id | Number1 | Number2 | +----+---------+---------+ | 2 | 90 | 40 | +----+---------+---------+ 1 row in set (0.00 sec)
