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