Fetch the maximum value from a MySQL column?

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Value int
   -> );
Query OK, 0 rows affected (0.63 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values(78);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values(89);
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values(98);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values(58);
Query OK, 1 row affected (0.25 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-------+
| Value |
+-------+
| 78    |
| 89    |
| 98    |
| 58    |
+-------+
4 rows in set (0.00 sec)

Following is the query to get the maximum value from a column −

mysql> select Value from DemoTable order by Value DESC limit 1;

This will produce the following output −

+-------+
| Value |
+-------+
| 98    |
+-------+
1 row in set (0.00 sec)
