Calculate average of column values and display the result with no decimals in MySQL

MySQLMySQLi Database

For this, you can use round() along with avg(). Let us first create a table −

mysql> create table DemoTable
(
   Score int
);
Query OK, 0 rows affected (0.68 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values(98);
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable values(97);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values(91);
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values(86);
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable values(45);
Query OK, 1 row affected (0.12 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+-------+
| Score |
+-------+
|    98 |
|    97 |
|    91 |
|    86 |
|    45 |
+-------+
5 rows in set (0.00 sec)

Following is the query to calculate the average of column values and display the result with no decimals −

mysql> select round(avg(Score),0) AS Average from DemoTable;

This will produce the following output −

+---------+
| Average |
+---------+
|      83 |
+---------+
1 row in set (0.00 sec)
