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)
