How to run direct DML (insert or update)

Rails
1

I want when the user clicks on a button on the browser
“Perform monthly billing run” the controller to lanch a sql DML
statment to be called (in the model?) than runs something like

“insert into billing (item, qnt, total_cost, billing_run_timestamp
select item, qnt, item*cost as total_cost, timestamp
from services
where service_end_date is null”

How can I run a DML (insert, update, delete) direct sql statement ?

Item.connection.execute(“select count(*) from items”)

or generally:

.connection.execute()
