I am doing a MariaDB tutorial at the moment. I access MariaDB by using HeidiSQL. I write the following function and its call into the query window of MariaDB:

`DELIMITER $$  
CREATE FUNCTION example\_function(id INT)  
returns INT  
return id;  
;

CALL example\_function(3);`

When I run the query, I get an error (FUNCTION example\_function already exists).

Is it possible to call functions from HeidiSQL’s query window? If so, how to do it?
