Execute MySQL query from the terminal without printing results?

Let us first create a table −

mysql> create table DemoTable709 (Amount int);
Query OK, 0 rows affected (0.62 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable709 values(100);
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable709 values(560);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable709 values(7800);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable709 values(1020);
Query OK, 1 row affected (0.15 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable709;

This will produce the following output -

+--------+
| Amount |
+--------+
| 100    |
| 560    |
| 7800   |
| 1020   |
+--------+
4 rows in set (0.00 sec)

Following is the query to execute MySQL query from the terminal without printing results −

mysql> set @TotalAmount=(select sum(Amount) from DemoTable709);
Query OK, 0 rows affected (0.00 sec)

If you want to see the result, you can use below query −

mysql> select @TotalAmount;

This will produce the following output -

+--------------+
| @TotalAmount |
+--------------+
| 9480         |
+--------------+
1 row in set (0.05 sec)
