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

MySQLMySQLi Database

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)
